All ElJay manufactured units (built before September, 1995) had a serialnumber that is designated in the following format: two numbers, a letter andfour numbers (12A3456) The first number indicates the type of equipment. 2indicates a crusher, 3 a screen and 4 a plant. The next number is used with thefirst number to determine the type of crusher, screen or plant.

21 - 36" crusher 32 - Incline screen 41 - Plant w/crusher only22 - 45" crusher 34 - Flat screen with gears 42 - Plant w/screen & crusher2A- 45" RCII crusher 35 - Heavy scalper 43 - Screening plant23 - 54" crusher 39 - Rebuilt screen 44 - Wet screen w/screw2B- 54" RCII crusher 45 - Plant with primary24 - 60" crusher 49 - Rebuilt plant25 - 66" crusher26 - 72" crusher27 - Sand cone28 - VSI29 - Rebuilt crusher

The letter in the serial number indicates the month that the unit was built. Theletters A-L are used with A being January and L being December. The next twonumbers following the letter indicates what number crusher, screen or plantmade that month (ie., 04 indicates the 4th unit built that month). The last twonumbers indicate the year the equipment was made.

Examples:23G0489 - A 54" crusher built in July, 1989. It was the fourth crusher builtthat month.

34I0977 - A flat screen with gears built in September, 1977. It was the ninthscreen made that month.

Screen Model Numbers ExplanationsFSG - Flat screen with gears

FS - Flat screen/chain

RH - Removable housing

The next digit in the serial number is the width of the screen. The next two digitsafter the screen width is the length of the screen. The last digit indicates thenumber of decks on the screen.

Following the serial number, there may be a two-digit number indicating thedrive assembly. Some of the more common numbers are 20, 22, 24, 26, 28 or32. The bearing size can be determined by multiplying this number by 5. Theresult is the bearing diameter, in millimeters. These numbers may be followedby the following notations: QS - Quarry scalper, CS - Chip screen, S - Scalper,HS - Heavy scalper, FP - Fines pan, SP - Special.

Examples:

FSG 5163-26 = A flat screen with gears, 5' x 16', triple deck with a 26 driveassembly.

FSG 4143-24SP = A flat screen with gears, 4' x 14', triple deck special witha 24 drive assembly

RH 5121-22 = Four bearing, 5' x 12' single deck incline screen

Crusher Selection GuideUse this guide to help you choose the crusher and configurationthat's right for your primary, secondary or tertiary crushingneeds. The following is a quick look at each crusher type andsome basic selection parameters.

Jaw Crushers

The overhead eccentric jaw crusher is the most universallyapplicable primary crusher. In sedimentary rock to the hardestgranites or basalts, this primary crusher operates effectively allover the world. The jaw crusher is a compression machine witha 6 to 1 reduction ratio. Generally in shot rock, material that is90% of the feed opening is acceptable. Normally in gravel,because of the tendency of the material to be more rounded,feed that is 80% of the opening is recommended. As a generalrule, discharge material is twice the crusher setting. Outputgradation is changed by closing or opening the dischargesetting.


15

Primary Impact Crushers

Recommend mainly for limestone and lower abrasiveapplications, single impeller impact breakers provide a cubicalproduct even in slabby material, improve aggregate quality andincrease plant capacity. The impact breaking action acts alongnatural cleavage lines to produce material with fewer thin sharpedges. Size of the impact breaker generally indicates the netfeed opening after VGF grizzly is placed into the chamberopening. With reduction ratios up to 20 to 1, secondary crushingrequirements are reduced when compared with a compressiontype primary. Impact breakers are normally used when materialis 10-15% abrasives or less. Output gradation is generallychanged by varying crusher speed and breaker bar setting.

Cone Crushers

Cone crusher have the same universal acceptance for secondaryand tertiary crushing as jaws do for primary work. Conecrushers can be the "all -purpose" machine in most sand andgravels where a feed size up to 13" requires no primary. In shotrock, cones perform as intermediate and/or finishing crushersfollowing a primary. For optimum performance, top feed sizeshould be limited to an average between A and B, where A isthe closed side feed opening and B is the open side feedopening. Cones, with a reduction ratio of 6 to 8:1 reducematerial to a minimum of 3⁄4" minus. Cones can reduce materialto a minimum of 1⁄4" minus with a reduction ratio of 4 to 6:1.Various liner configurations adapt each machine according tofeed size and product requirements. Discharge gradation ischanged by opening or closing the closed side setting.

Horizontal Shaft Impactor Crushers

Combining the benefits of impact crushing with the applicationof high chrome technology, the secondary impactor provides acubical product (necessary with today's tighter specifications)in material previously too abrasive for impacting. With areduction ratio of up to 12 to 1, secondary impactors can reduceor replace finish crushing. Top size feed is approximately 12"to 22" with minimum product being 3⁄4". Output gradation isvaried in two ways. The primary means is changing rotorspeed. The higher the speed, the finer the product. Increasingthe speed also increases wear. Secondly, adjusting the apronsalso affects output gradation.

Roll Crushers

When a special product size is required, a roll crusher may bean often-forgotten tool. This compression type crusher producesmore of a banded product range than any other crusher. A dualroll crusher is limited to a 2 to 2-1⁄2 to 1 reduction ratio. The tripleroll is a 4 or 5:1 reduction machine. It is vitally important thatfeed material is spread across the face of the rolls to maximizeproduction and provide even wear. Output gradation is changedby opening or closing the discharge setting. Also, rolls are notaffected by moisture or plasticity as are cone crushers.

Vertical Shaft Impact Crusher

Like the secondary impactor the vertical shaft impact crushercombines impacting benefits with high chrome metallurgy. It isa finish crusher producing a desirable cubical product.Depending on crusher configuration, material as abrasive as70-90% can be handled by the VSI. Feed size maximum islimited to 3⁄8" to 6" depending on crusher model and crushingchamber configuration. The VSI is an excellent machine forproducing concrete rock, chips and manufactured sand. Anvilsgive better control of reduction flexibility; higher impeller speedsgenerate a finer product; the enclosed rock rotor saves wearcost in high abrasion materials and offers highest speed.

Hammermills/Limemills

In a high quality limestone, an abrasive content of less than 5%allows utilization of a mill-type crusher, providing the marketexists for the considerable amount of fines generated. Thehammermill is usually in a secondary application accepting upto an 8" feed and providing a reduction ratio of 20 to 1. Limemillsare specifically designed for production of quality ag-lime andwill accept feed size up to 4". Selecting the proper grates,breaker plate position and crusher speed determine the crushergradation for both units.

Jaw Crusher SizesThe first two digits indicate the bite, or distance, in inchesbetween the stationary and movable jaw plates (dies) at the topof the crushing chamber. This dimension controls the feed size.The last two digits are the width, in inches, between the sidecheek plates. This dimension controls the capacity.

Note: Not all sizes are currently produced.Closed stroke is measured from crown to crown of jaw plateswhen jaws are as close together as possible at discharge end.

Closed stroke settings are determined with new jaw plates andstandard toggle plate. Jaw plate wear, toggle plate wear andtype of toggle plate, if other than standard, will affect settingcapability. Material factors such as friability, work index,compressive strength, high fines content, moisture content willalso affect setting capability.

Minimum setting for standard duty jaw crusher based on 35,000psi rock. For rock harder than 35,000 psi, consult factory.

Warning - Do not exceed 6:1 reduction ratio at minimumsettings.

Andreas Style Crusher - Model 1516Gradation Curves


32For All Impactors When Ordering Be Sure to Specify

1. Percent of silica plus combined percent aluminum andiron oxide.

2. Type of stone in quarry.

3. Size of stone to be fed.

4. Size of finished stone.

5. Is finished product to be made in one pass or is product tobe passed over sizing screen in a closed circuit.

6. Power unit, type, HP, RPM and keyway in PTO.

Primary Impact Breaker

The gradation chart on the following pages gives the percentpassing a given square opening screen at various rpm's for thevarious breakers. For example, read down the model columnto the correct model and then across to the correct impellerspeed.

Percentage figures for double impeller impact breaker arebased on both impellers operating at the same speed. Ratio offines to larger sizes can be increased or decreased by changingthe speed of the impeller. Variation of speed can be determinedby a test run.

These charts are intended as a guide only and percentagesvary with nature and condition of the material processes. Forfurther information on product sizes consult the factory.

Capacities of Rollercone® Cone CrusherThe charts on the following pages show capacity ranges basedon igneous rock (basalt, granite, etc.). These charts are to beused as guides to crusher and liner selection. Material processingincludes many different factors that affect crusher performance.These charts are based on the following factors:

1 Less than 10% undersize (smaller than the CSS) incrusher feed.

2 Plastic material limited to where no "pancakes" are beingcreated.

3 Proper crusher manganese configuration.

4 Moisture content of feed material below 5%

5 Uniform feed gradation

6 Proper feed distribution 360° around the feed opening

7 Use of the Fine Head feed control device when required

8 Proper crusher RPM under full load

9 Support equipment must be properly sized and in goodoperating condition including: conveyors, screens, electricmotors, V-belt drives, support structures, undercrusherhoppers and feeders.

Feed openings are based on new manganese and idealscreening conditions. Due to the wear pattern it is not possibleto maintain a constant feed opening as take up occurs. Minimumclosed side setting is that point just above bowl float undermaximum allowable pressure on the tramp iron relief system.This setting can vary widely depending on nature and conditionof the material being crushed. Under some conditions when thesetting is too close, "pancakes" will form and the bowl will float.If this condition exists, the setting must be increased until bowlfloat is eliminated. Data is offered as a guide only. Crushingcharacteristics of various rock and crusher operation will affectresults. Capacities based on material weight of 100 lbs/cubicfoot.

Rollercone Classic Approximate Weights - lbs & kg

Weights of same size crushers will vary due to differences in majorcastings.

Rollercone® Classic Setting & Capacity Charts

The charts on the following pages show the average capacitiesin igneous rock (basalt, granites, etc.).

Feed openings are based on new manganese and idealscreening conditions. Due to the wear pattern, it is not possibleto maintain a constant feed opening as take-up for wear occurs.

Under some conditions, when setting is too close, "pancakes"will form and the bowl will float. If this condition exists, thesetting must be increased until bowl float is eliminated.

61Rollercone II Specifications

Material processing includes many different factors that affectcrusher performance. The minimum closed side setting is theclosest setting possible that does not induce bowl float. Theactual minimum closed side setting possible at a given crushingsite can vary widely, depending on the nature and condition ofthe material being crushed, as well as common variations incrusher operating styles. The factors listed below are critical forproper crusher operation:

1. Do not exceed maximum allowable pressure in the trampiron relief system.

2. Do not allow more than 10% undersize (material smallerthan the closed side setting) in the crusher feed.

3. Keep plastic material limited to where no "pancakes" arebeing created.

4. Install and maintain the proper manganese configuration.

5. Do not allow more than 5% moisture in the feed materiel.

6. Maintain uniform feed gradation.

7. Maintain proper feed distribution 360° around the feedopening.

8. Use the fine chamber feed control device when required.

9. Maintain the proper crusher rpm under full load.

10. Make sure that support equipment is properly sized and ingood operating condition. This includes conveyors,screens, electric motors, V-belt drives, support structures,undercrusher hoppers and feeders.

88HSI Gradation Curves

The above curves show approximate gradation for various sizes ofsecondary impactors at various speeds. The numbers on each curve arethe fpm the curve represents. The chart is based on average limestoneand breaker plate settings of 2" and 1". Gradation will vary dependingon particle size of feed, rate of feed, hardness of rock and naturalbreaking characteristics.

91VSI Application Specifications

TPH is an estimate based on maximum feed size shown passing squarescreen cloth opening. A reduction in feed size will increase crusherthruput. Cutting feed size in half can increase TPH by 20%. Capacityfigures are shown as total TPH thru crusher. Total = New Feed plusRecirculating Load.

VSI Horsepower Requirements

This chart may be used as a guide to estimate the horsepower requiredper ton when producing different size materials with different crushingchamber configurations. It assumes hard stone or gravel.

Hammer Options

Fasturn - tip on solid arm; tip can be turned 180° without removing arm.

Finger clamp (Clark) - tip on split arm; tip and arm can be turned 180°,arm must be removed.

Long arms produce maximum fines. Short arms produce coarsermaterial.

Hammer Weight Balancing

Hammer weights must be balanced between rows to ensure minimumvibration. Heaviest hammers should be mounted centrally on thespinner and lighter ones toward the outside. If there is more than twopounds difference between rows on a two-row spinner or between anytwo rows on a three-row spinner, hammers must be interchanged toobtain a balance within two pounds. Speeds over 1000 rpm require moreaccurate balance.

When Ordering Be Sure to Specify:

1. *Percent of silica and other abrasive oxides present.

2. *Type of stone in quarry.

3. Size of stone fed to mill.

4. Size of stone.

5. If finished product is being made in one pass or if it is to be passedover sizing screen in a closed circuit.

6. Power unit, type, hp, rpm and keyway in PTO.

7. Always specify type of drive: V-belt or direct.

With this information we can recommend correct grates for bestperformance.

*If in doubt send small sample to Cedarapids Inc.

Hammermill SizeHammermill size is determined by the distance between the inside of theside plates and diameter of hammer swing, ie 40" x 33".

How to Control Product Size

Product size is controlled by breaker plate setting, hammerRPM and grate combinations. The standard combinations andtype of product for each are shown in the tables in this section.

For ease in changing breaker plate setting, a hydraulic ram andpump are available as an optional extra. The hydraulic ram isused to move the plate in toward the hammer circle. To use thehammermill as an impact breaker, using two rows of hammers,a lower liner plate and grate filler ring, optional extra, replace thegrates.

108Hammermill Gradation ChartsFor 20", 30", 40" & 50" Units

The estimated product gradation figures given in the two chartsare based on use of three rows of new hammers with breakerplate set within 1⁄2" of hammers. Feed was minus 4", plus 1-1⁄2",dry, medium hard (3.5 Mohs') limestone. A breaker platesetting of 1-1⁄4" from hammers (just covering body plate) givesproduct gradation approximately the same as 2-row operationfor the speeds given at head of each column.

Note: For 2-row operation instead of 3-row for 1⁄2" breaker platesetting, use figures from columns 150-300 rpm slower thancolumn selected; that is, 2-row at 1200 rpm approximatelyequals 3-row at 1050 rpm. The figures used in these charts areto be considered as a guide only. Hardness of local deposits,condition of hammers and grates and breaker plate setting willaffect all gradation.

Size Feed in Relation to Discharge Opening

Angle ofNip 14°

Maximum Feed Size

Crusher Opening

Sizing Feed to CrusherIf particle size is only slightly larger than the discharge opening,very little reduction takes place and the potential capacity is notfully used. If particle size is too large, material is not crusheduntil the weight of the material above it eventually drives itbetween the rolls. When material builds up in the hopper, theshells are subject to unnecessary rubbing wear.

Maximum efficiency and minimum wear occur when properlysized particles are fed at a rate which produces no excessivebuildup but maintains just enough buildups to keep the level ofmaterial just above the point at which the particle will begrabbed and pulled between the rolls.

Refer to "Roll Crusher Maximum Feed Size in Inches" table andthe roll crusher Operation & Maintenance Manual for furtherinstruction.

CAUTION!Crushers can be damaged if operated in excess of theseproduction rates, particularly at fine setting and low reductionsratios.Note: 1. Rate shown represent total feed to crusher.

(including circulating load, if in closed circuit)2. Rates at other shell speeds are directly proportional.3. Rates based on material density 100 lbs/cu. ft. Other

densities proportional.4. Consult other charts for maximum feed size and

recommended settings.

Three Roll Crushers

Three-roll crushers can provide twice the reduction ratio of a dual roll crusher. Asingle-feed, three roll with a 20/80 or up to 66-2⁄3 - 33-1⁄3 split will produce greatercapacity and a smaller percentage of overs as its second stage does not have tore-crush material reduced to finished size by the first stage. These particles fillthe voids at the second stage, resulting in a denser material ribbon.

At higher material size split ratios, the dual feed will "out produce" the single feedbut a much larger screen is required to handle the large recirculating load. Forthis reason in a closed circuit operation, the single feed method is preferred. Thebest application for dual feeding is in open circuit with other suitable crushersfollowing to handle the high percentage of oversize passing through the three-roll.

NOTE: Up to 700 FPM shell speed permissible on 40" diameter andlarger rolls. Up to 1800 maximum power RPM. For finecrushing applications use maximum hp shown. For larger-than-normal feed, an increase in power may be necessary.Consult factory.

** Used as drive pulley; standard size given, but may vary with drivearrangement.

128Vibrating Screen Capacity

Before the capacity of any screen can be estimated it is necessary toknow the various factors and conditions that regulate screen production.The tables and formula given below can be used to more accuratelydetermine capacity of a screen.

FORMULA: A= B x S x D x V x H x T x K x P x W x ONote: Factors S, K, P and W will usually be constant for a given set ofcalculations and may be combined into one figure by multiplying themtogether. Also see Screen Bed Depth data.A= Actual capacity to screen deck, which can be screened at 90%

efficiency, per sq. ft.B= Basic capacity (See Table I)S= Incline factor (See Table II)D= Deck factor (See Table III)V= Oversize factor (See Table IV)H= Halfsize factor (See Table IV)T= Slot factor (See Table V)K= Condition factor (See Table VI)P= Shape factor (See Table VII)W= Weight factor (See footnote Table I)O= Open area factor (See Table VIII)

When selecting a screen to separate crusher-run material, it is necessaryto tabulate from a gradation curve the percent passing the screen clothsizes required and the percent passing 1⁄2 the screen cloth size. Gradationfor the example below is: percent passing 3" -100%; 1-1⁄2" -92%; 3⁄4" -80%; 3⁄8" -62%; 3⁄16" -40%; 8M -21%.EXAMPLE: Select a screen to separate the following sizes: plus 1-1⁄2";1-1⁄2" – 3⁄4"; 3⁄4" – 4M; minus 4M.DATA: Production 250 TPH; Material - clean, cubical gravel; Weight 115lb/cu. ft.; 15% slivers in the minus 1⁄2" to plus 1⁄8" range; triple deckhorizontal screen to be used. Square clear opening determined fromCedarapids screen cloth bulletin.CALCULATIONS:1. Top Deck – 100% of feed, 1-1⁄2" separation

A=B x S x D x V x H x T x K x P x W x OS=* 1.20 (Table II)B= 6.50 TPH/sq. ft. for 1-1⁄2" SCO (Table I)D= 1.00 (Table III)V= 0.926 for 8% oversize (Table IV)H= 1.80 for 80 % halfsize (Table IV)T= 1.00 for square opening cloth (Table V)K=* 1.25 for clean gravel (Table VI)P= 1.00 for less than 5% slivers (Table VII)W=* 1.15 for 115 lb./cu.ft. (Table I footnote)O= 1.28 for 64% opening (Table VIII)


129

*Items thus marked are constant for these calculations and can becombined into Q. K x W x S = 1.725 = Q.A= (6.50)(1.00)(.926)(1.80)(1.00)(1.00)(1.00)(1.28)(1.725) = 23.9 TPH/sq. ft.

2. Center deck - 92% total feed, 3⁄4" separation. Actual percentage ofmaterial size to this deck will be 100 ÷ 92 or 1.087 times the percentagefound in the gradation curve.A= B x D x V x H x T x P x O x Q

B=4.80 for 3⁄4" openingD=.90V=.942 x 1.087 x 12% oversize = approximately 13% or 3⁄5 the

difference between 10% and 15% factors in Table IVH=1.550 x 1.087 x 62% halfsize = 67.39% or approximately 2⁄5 the

difference between 65% and 70% factors in Table IVT=1.0P=1.0O=1.21 for 60.5% clear openingQ= 1.725

A= (4.80) (0.90) (0.942) (1.550) (1) (1) (1.21) (1.725)= 13.1 TPH/sq ft

3. Bottom Deck - 80% of total feed, 4M separation, slotted wire. 100/80= 1.25A= B x D x V x H x T x P x O x Q

B=1.80 for 4 meshD=.80V=1.18 (50% oversize)H= 0.725 (1.25) (21% halfsize)= 26.25% or approximately 1/5

the difference between 25% and 30% factors of Table IVT=1.40P=1.0O=1.21 for 60.5% clear openingQ=1.725

A= (4.80) (0.90) (0.942) (1.550) (1.00) (1.00) (1.21) (1.725)= 13.1TPH/sq ft.

Therefore the deck area required for each deck to handle 250 TPH totalfeed is :

Top deck - 250/23.9=10.46 sq ft.Center deck - (250) (92)/13.1=17.55 sq ft.Bottom deck - (250) (80)/3.48=57.50 sq ft.

The bottom deck in this case controls the size of screen unit required. A60" x 12' screen will provide 60 sq ft of area on each deck and will fulfillthe requirements.

Amount of Water Required for Washing AggregateAs a general rule, 5-10 gallons of water per minute per ton ofmaterial per hour should be available for washing under aver-age conditions, based on total amount of material fed to screen.

Spray bars should be mounted so that spray is with or towardsflow of material. Using high pressure spray perpendicular to thescreen surface will only drive near-size material into screensurface, causing blinding.

Sand Classification

Capacities, horsepower and screw speeds given in the tablesare from Eagle Iron Works and are based on washing concretesand. In washing, classifying and/or dewatering material of thefiner mesh sizes, or material with over 15% passing the 50mesh screen, turbulence becomes a critical problem.

To correct this, turbulence must be reduced by slowing downthe screw speed, thus allowing the fine mesh particles to settleand be conveyed out as part of the product. Slowdown requiredis dependent on the percentages of fine sand present. Seespecific screw specifications for recommended screw speedreductions.

When determining gallonage needed, all water must be includedin the total gallons per minute in considering water capacitiesfor fine material units - such as water used for the Hydrotexbearing, drain-board flushing pipe, water already in the feedand additional dilution water if needed when handling high-percentage silt feed.

Information concerning Eagle Iron Works units is presented asa guide only and not intended to promote one manufacturerover another. For specific applications, contact any sandwashing equipment manufacturer.

*Power requirements are based on electric motors and on handling gravel. If thewasher is handling a high percentage of maximum sized material, or if the washeris handling crushed stone or ore, the capacity of the unit will be reduced. Installationof paddles in place of screw flights will also reduce capacity slightly and if more thansix sets of paddles are employed on each conveyor shaft, larger motors will berequired. When replacing electric motor with gasoline or diesel engine, multiply theelectric motor HP by 1.5 and select an engine with a corresponding continuous HP- if continuous HP is not given, use 80% of maximum HP given for the engine.

149Electric Power Information

Specify voltage when ordering electrified plant or part of plant. Specifyhigh starting torque motors for all Cedarapids horizontal vibratingscreens.

Electric Power Control Equipment

Electric power control and distribution to the electric drive motors (ifsupplied fully-wired by Cedarapids) will meet the general specificationsof the National Electric Code relating to machine tool type applications.The power distribution cabinet has a weather-resistant enclosure asstandard. The power supply is considered 460 volts, 3 phase, 60 cycleunless otherwise specified. 380 volts, 3 phase, 50 cycle; 575 volt, 3phase, 60 cycle or 415 volt, 3 phase, 50 cycle can be provided. Consultfactory for correct application. Due to the variables involved in the total-plant installation, the customer will supply his own main power disconnectand power supply leads to the plant power distribution cabinet unlessthese items are specifically ordered. Electric power distribution to theindividual electric drive motors from the power distribution cabinet is bymine-type cables, each carrying its continuous grounding lead unlessotherwise specified. Push button control of the individual drive motorstarters is by 115 volt, 60 cycle or 220 volt, 50 cycle control.

Specific wiring to meet local requirements must be specified on the orderand a copy of the local requirements be sent to Cedarapids Inc. Pricingof electrical equipment by Cedarapids is based on the above generalspecifications. Deviations to meet specific area code requirementsrequires pricing considerations by Cedarapids.

Electric Grounding

When Cedarapids supplies the electric-drive motors and their associatedcontrols completely wired as part of the original equipment, the motorshells are grounded to the control cases or panels by Cedarapids. Thestarter cases or control panel must be grounded by the customer. Whenelectric drive motors only are supplied or when motors and controls aresupplied unwired, no electric wiring is supplied and no grounding tie-insare supplied. All electrical grounding must be done by customer.

It is the customer’s responsibility to adequately ground the individualunits, or with a completely wired plant to ground the units so tagged. Soilconditions vary so widely between localities it is impossible for Cedarapidsto supply grounding equipment adequate to meet all conditions andcomply with local codes.

150Horsepower Ratings

Note: Our catalog and price book ratings of engine horsepower arecontinuous ratings, not peak ratings unless otherwise specified.

Gasoline Engines (Effect of Altitude & Temperature)

Output horsepower decreases with an increase in altitude and/or ambienttemperature. Aspirated engine horsepower decreases by 3% for every1000 ft above 3000 ft and/or 2% for each 10°F increase in ambienttemperature above 80°F. Turbo charged engines are capable ofmaintaining their rated output to a considerably greater altitude andambient temperature. The significant differences between models andmanufacturers makes it necessary to individually determine the capabilityof each unit.

Diesel Engines (Altitude Effect on Diesel Engine)

Due to the many variables involved, establishing a general rule foraltitude derating is difficult. Barometric pressure, air temperature andhumidity also affect the engine’s performance. Engine design andsupercharging make a difference. Each engine manufacturer establishesits own performance data.

Consult Cedarapids or engine manufacturer for specific information onderating.

Diesel Electric Set

A diesel electric set consists of the diesel engine and generator. Eachhas different characteristics. The diesel will stall under excessive load;the generator will attempt to meet the load and destroy itself. The dieselmust have sufficient power to maintain the generator at operating speedunder running and motor-starting conditions. The generator must becapable of supplying this power without causing damage to itself.

The KW requirement of a generator must include the voltage andfrequency at which it is to be operated. Generators are normally ratedin KW, not to be confused with KVA. For most applications a KW is 1.25KVA or 1 KVA is 0.8 KW.

Effect of Altitude & Temperature

Kilowatt output from diesel electric generator sets decreases with anincrease in altitude and/or ambient temperature. Aspirated enginehorsepower decreases by 3% for every 1000 ft above 3000 ft and/or 1%for each 10°F increase in ambient temperature above 85°F. Turbocharged engines are capable of maintaining their rated output to aconsiderably greater altitude and ambient temperature. The significantdifferences between models and manufacturers makes it necessary toindividually determine the capability of each unit.

This generator sizing involves generators supplied by Cedarapids. Ifothers are supplying the generator, it is imperative the list of motors befurnished to the generator supplier so proper accessories for motorstarting are supplied.

Motor starting abilities for generators of various sizes and from differentvendors will vary.


151A different application is when a generator is driven off an engine drivingother equipment as in crushing applications. If a Lima MAC-R generatoris used, it can be sized 1 KW per horsepower. Example: totalhorsepower adds to 125 hp, a 125 KW generator will suffice. Allow 1.5hp of engine for each KW of generator.

If a single large motor, or if one motor comprises a high percentage oftotal hp and a diesel electric set is used, a generator supplier should beconsulted.

Note: The term “power factor” refers to electrical characteristics only andnot to the loading factor of motor or generator.

Wire Size

Current carrying capacity – or wire size – must be ample to keep voltageat motor within 5% of motor nameplate rating for adequate motoroperation.

For best operation of electric motors, voltage should be between 460Vand 470V for 460V motors. Some power companies are alreadyoverloaded. When selling an electrified plant which will be connected toa power company’s line, make sure there will be ample power availableto start and operate the plant.

Determine the largest motor size on which the power company will allowline starter starting – use reduced voltage starters on all larger motors.

158Cedarapids Strigid® ConveyorsSimplified Selection ProcedureFollowing is a step by step method of determining what sizeStrigid conveyor will best suit your requirements. Note thatthese conveyors are NOT currently part of Cedarapids, Inc.production. This data is for information only

STEP 1. For Maximum Recommended Incline, based on typeof material handled, see Table A. Then, knowing the actual liftheight required, the suitable conveyor length can be foundusing the Conveyor Elevation Chart.

STEP 2. Belt width required depends on "lump" size andcapacity. Table B shows maximum lump size, for both "sized"and "unsized" material, for each belt width. Table C listscapacities for each belt width in both tons and yards per hour for20°, 35° and 40° trough idlers and at various belt speeds in feetper minute. Standard conveyors operate @ 350 FPM but otherspeeds are available. Table D lists maximum free fall distancesfor various lump sizes and belt types.

Caution: Belt width determined from Table B and C may differ.Always select the wider belt size determined to satisfy bothconditions.

STEP 3. Horsepowers are found in Tables E, F and G. Thefigures from these charts must be added to obtain the totalhorsepower required. Table E lists horsepowers to drive emptyconveyors. Table F lists HP to drive loaded conveyorshorizontally. Table G gives HP to lift load. Interpolate lengthsnot shown.

NOTE: On declining (downhill) conveyors, subtract HP fromTable G.

EXAMPLE: Select a conveyor to handle 3-1⁄2" sized (no fines)stone at a discharge height of 44' with a capacity of 300 TPH.

STEP 1. Maximum incline = 16°, Table A. Length = 160',Elevation chart.

STEP 2. Width 18" - Table B. Width 24" - Table C. Select 24"min. width.

STEP 3. Power = 2.93, Table E. + 3.03, Table F. + 13.34, TableG. Total = 19.3 HP required. Use 20 HP drive.

163Note: Total HP = E + F = G. If "G" is greater than 2⁄3 (E + F) usea backstop. Add 1⁄10 HP per foot of skirtboard when skirtboardis on both sides of conveyor. HP to accelerate load is 1⁄2 (E +F). On downhill conveyor "G" is negative. Use at least (E + F)to prevent over speeding. Use a spring-set electric releasebrake motor.

To Find the Approximate Length of Beltin a Roll When Closely Coiled

RULE: Add together the diameter of the roll and the diameterof the center hole, both in inches; multiply by the number of coilsin the roll by 0.131. The result will be the approximate length infeet regardless of the thickness of the belt.

EXAMPLE: How many feet of belting in a roll 48" in diameterwith a 6" center hole and 60 coils? 48 + 6 = 54; 54 x 60 = 3240;3240 x 0.131 = 424,440 or about 424' 5".

165Conveyor Capacity Chart

Material Weight in Pounds EqualsConveyor Capacity in TPH

Example: Assume belt speed is 200 FPM. Refer to the tableand find belt speed of 200 - the figure opposite shows length ofbelt for calibration: 6'-0". Stop conveyor and measure off 6' onbelt. Remove all material between marks. Weigh this materialand assuming the weight is 170 lbs., the belt is delivering 170TPH.

To determine the amount of material in TPH being handled bya belt conveyor, it is only necessary to know the belt speed andthen weight the material on a certain length of the belt asspecified in the table below. First, determine the belt speed,then refer to the table; the figure in the column opposite the beltspeed will show the length of material on the belt to be weighed.Each pound of material on this length of belt represents one ton-per-hour of material being handled by the conveyor.

Based on 37° angle of repose; 100 lbs/cu. ft. material. Above table is approximatefor use as a guide only.

To Find the Volume of a StockpileUse the formula: Volume = .2618 x D2 x hExample: To find the volume of a 10' stockpile that has a 26'-6"diameter.

Volume = .2618 x (26'-6")2 x 10Volume = 1838.49 cu. ft.Volume (in cu. ft.) x weight/cu. ft. ÷ 2000 = tonsVolume (in cu. ft.) ÷ 27 = Volume (in cu. yds.)

Horsepower is rated at 1200 rpm motor speed.Note: Approximate capacity through grizzly is 5 tph x sq ft of grizzly areax nominal opening. Calculations based on 100 lb/ft3 material weight.Example: 42" feeder, 60" grizzly, 4" nominal opening. 5 tph x 17.5 sq ftgrizzly area x 4" nominal opening = 350 tph.This capacity will vary greatly from shot rock to gravel.Rates based on level operation.

Actual capacities dependent upon type and characteristics of material.Capacities reduced considerably when handling coarse or sticky material.

169Capacities of Apron Feeders in Tons-Per-Hour

Capacities given are based on quarry run material weighing 100 lbs percubic foot - depth of material is equal to half the feeder width uniformlyloaded. Values given assume uniform loading to 75% of the maximumcubical contents. For other weights of material and other travel speeds,these values will increase or decrease in direct proportion.The maximum capacity must be used as a basis in selecting the size ofthe apron, even though this maximum rate exists for a few seconds only.The average or minimum hourly rate must not be used.

174Tests Used to Determine Physical Properties of Rock

Material tests follow ASTM procedure and include abrasion, compressivestrength, toughness, the Burbank test, the L.A. "Rattler" test, andspecific gravity.Chemical tests for abrasive effect include:Abrasives Related to Abrasive EffectSilica Dioxide—SiO2 Magnesium Carbonate—MgCO3

Calcium Carbonate—CaCO3

Iron Oxide—FeO & Aluminum Oxide—Al2O3

Abrasive test data is needed primarily in the consideration of impact orgrinding type crushers and relates to the maintenance cost data. Wherepressure crushers are involved, testing for abrasives is normallyunnecessary, although a high abrasive content will cause more crusherwear. Samples sent to the factory for chemical analysis only should be1 to 2 Ibs. and must be representative of the quarry. (Note: If a gradationand/or crusher test is to be run also, representative sample should be100-250 lbs. )

Rock Compressive Strength (ASTM C170)5,000-10,000 PSI—Soft; 10,000-20,000 PSI—Medium; 20,000-30,000PSI—Hard; 30,000-45,000 PSI—Very Hard; over 45,000 PSI—ExtremelyHard.Generally rock up to 40,000 PSI with acceptable hardness and toughnessvalue is considered suitable for reduction in Cedarapids compressioncrushers. The choice of impact or grinding type crushers will be dependenton abrasive content.It is possible to apply Cedarapids crushers in material over 40,000 PSIbut only after consultation with the factory. A solid 12" cube sampleshould be sent for analysis for compressive strength.Hardness (Mohs scale) and related material toughness provide an indexfor application of impact and grinding mills.Both hardness and toughness (ASTM D-3) indices also will be consideredin pressure crushers in combination with compressive strength .

Procedures used in the various tests ore:Compressive Strength (ASTM C170)1. Prepared sample—cylinder of rock approximately 2" cubed.2. Cube of rock is placed between a special bearing block and the head

of a suitable universal testing machine.3. Unit crushing strength is calculated in Ibs. per square inch.

Toughness Test (ASTM D-3)1. Sample—Cylinder 25mm high and 25mm in dia.2. Steel plunger with spherical lower end resting on sample is subject

to impact of a 2 kg. hammer. The energy of the blow is increased byincreasing the height of fall of the hammer 1 cm. after each blow.

3. The height of fall in centimeters at failure of the specimen is calledtoughness. H (In. Cm) = Toughness.


175L.A. "Rattler" Test by Los Angeles Machine (ASTM C131)1. Size of sample—5000 grams of clean, dry aggregate, properly

graded (A).2. Sample placed in machine which is then rotated for 500 revolutions

at 30 to 33 R.P.M.3. Aggregate then removed and screened on a No. 12 sieve. Material

retained on screen then washed, dried and weighed (B) .4. Percentage of wear = (A-B)÷A

Specific Gravity Test (ASTM C127, C128)1. Size of sample - 5 kg. plus 3⁄8" aggregate.2. Wash to remove dust—then dry at 110° C temperature.3. Immerse in 15° to 25°C water for 24 hrs. and then weigh (B).4. Determine weight of sample in water (C).5. Dry again at 110° C temp. and weigh (A).6. Bulk specific gravity = A ÷ (B-C)7. Apparent specific gravity = A ÷ (A-C)

Some of the more common test procedures for aggregate quality, usedby highway department testing laboratories, etc., but not normally takenor evaluated by Cedarapids include:

Absorption Test1, 2, 3, 4, 5, and 6. Same as specific gravity test above.7. Absorption, per cent (%) = (B-A x 100) ÷ A

Burbank Wear Test1. Prepare four charges of 400 grams of properly graded 3⁄4" x 3⁄8" rock

that has been dried.

2. Weigh steel paddle to .000x of gram.

3. Run each charge of rock for 15 minutes in Burbank machine andremove. Run same steel paddle in machne for all four charges(1 hour).

4. Weigh paddle to .000x of gram and calculate weight loss. Weightloss in grams is the Abrasion Index Number.

ASTM C33-71aFine AGG Grading

The Fineness Modulus is an empirical factor obtained by adding the totalpercentages of a sample of aggregate retained on each of a specifiedseries of sieves and dividing the sum by 100.It is a definite indication of the surface area of the aggregate and relatesto the workability of the mixture.Sieve sizes used are No. 100 (149 micron), No. 50 (297 micron), No. 30(596 micron), No. 16 (1.19 mm), No. 8 (2.38 mm), No. 4 (4.76 mm) and3⁄8", 3⁄4", 1-1⁄2" and larger, increasing in the ratio of 2 to 1.

Not more than 45% shall be retained betweenany two consecutive sieves.Fineness Modulus (FM) shall not be less than2.3 or more than 3.1.For specific data see ASTM Book of Standards.

Energy Required to Crush Small SizesMore energy, relatively speaking, is required to crush quarried stone tovarious sizes. Below are some average figures from a member companyas reported to a National Crushed Stone Association workshop.

The metric system is a decimal system using the meter (39.37 inches) and gram(0.3527 ounces) as basic units. The liter (1.0567 liquid quarts or 0.9081 dry quarts)derives from meter measure. Certain prefixes denote multiples of the bases: decca-(10); hecto- (100); kilo- (1000); myria- (10,000); mega- (1,000,000). Conversely,other prefixes denote divisions of the bases: deci- (1⁄10); centi- (1⁄100); milli- (1⁄1000);micro- (1⁄1000000).

Metric TablesThe most commonly used names are printed in bold.

1. Measurements of Length10 millimeters (mm) = 1 centimeter (cm) = 0.3937 inches10 centimeters = 1 decimeter (dm) = 3.937 inches10 decimeters = 1 meter (m) = 39.37 inches or 3.28 feet10 meters = 1 decameter (dkm) = 393.7 inches10 decameters = 1 hectometer (hm) = 328 feet, 1 inch10 hectometers = 1 kilometer (km) = 0.62137 miles10 kilometers = 1 myriameter (mym) = 6.2137 milesThe micron (µ) is one millionth of a meter or one thousandth of a millimeter.

2. Measures of Surface100 square millimeters (mm2) = 1 square centimeter (cm2)100 square centimeters = 1 square decimeter (dm2)100 square decimeters = 1 square meter (m2)100 square meters = 1 square decameter (dkm2)100 square decameters = 1 square hectometer (hm2)100 square hectometers = 1 square kilometer (km2)

3. Land Measures1 square meter (m2) = 1 centiare (ca) = 1550 square inches100 centiares or 100 m2 = 1 are (a) = 119.6 square yards100 ares or 10,000 m2 = 1 hectare (ha) = 2.471 acres1 square kilometer (km2) = 1,000,000 m2 = .3861 sq. milesThe square kilometer is used in surveys on a large scale, or in maps or charts thatshow roads, plans of towns, contour lines, etc. The hectare is used for fieldmeasurements, like our acre. For city lots and the like, the are is generally used.

4. Measures of CapacityThe standard unit of capacity is the liter, equal to 1 cubic decimeter or 0.9081 dryquart or 1.0567 liquid quarts.10 milliliters (ml) = 1 centiliter (cl) = 0.338 fluid oz.10 centiliters = 1 deciliter (dl) = 6.1025 cubic inches10 deciliters = 1 liter (l) = 0.9081 dry quart or 1.0567 liquid quart10 liters = 1 decaliter (dkl) = 0.284 bushel or 2.64 gallons10 decaliters = 1 hectoliter (hl) = 2.838 bushels or 26.418 gallons10 hectoliters = 1 kiloliter (kl) = 35.315 cubic feet or 264.18 gallons

Use the following torque charts to avoid overstressing standardnuts and bolts used on Cedarapids equipment. Thesespecifications should be followed unless specific torques aregiven in our equipment manual. Cedarapids uses Grades 2, 5,and 8. The maximum torque values are based on 75% of thespecified minimum proof strength of the bolt steel in order toprovide a safety factor. The term "lube" includes the applicationof thread lubricants, cadmium plating, and the use of hardenedwashers.

Steel type and hardness range are as follows: For SAE Grade2 plain low carbon (1018 or 1020) steel, hardness is Rockwell"B" 85-100. For SAE Grade 5 plain medium carbon (1035,1038, & 1045), hardness is Rockwell "C" 19-30. For SAE Grade8 medium carbon alloy (4140, 8642 & 5147), hardness isRockwell "C" 32-38. All SAE bolt head symbols are listed on theTorque Chart next to the SAE grade.

ASSUMPTIONS:(1) The maximum torque values are based on 75% of the

specified proof strength.

(2) The term "lube" includes the application of thread lubricants,cadmium plating, and the use of hardened washers;regardless of whether standard or lock nuts are used.

197Explanation of Aggregate

and Bitumens TermsABRASIVES - A substance for abrading as for grinding polishing etc.Practically every nonmetallic mineral is highly abrasive. A great variety ofsilica and silicate minerals are mined commercially for their abrasive value intheir natural stateAGGREGATE - The mineral material, such as sands, graved shells, slags orbroken stone or combinations thereof with which cement or bituminousmaterial is mixed to form a mortar or concrete. Fine Aggregate may beconsidered as the material that will pass a 1⁄4 inch screen. Coarse Aggregate asthe material that will not pass a 1⁄4 inch screen.AGRICULTURAL LIMESTONE - Ground and pulverized forms of limestoneused for direct application to the soil.ALUMINOUS SILICATES - Several nonmetallics in this group are sometimesmined domestically - andalusite, sillimanite, kyanite, dumortierite, mullitet,topaz, etc. Kyanite (which see) is the only one reporting any data. Usuallyassociated in nature with other minerals they convert to mullite for refractorypurposes.AMBER - Many types of plants, particularly fir trees and pine trees give off asticky substance called resin which soon dries and hardens. Hard fossil resinfrom ancient trees is known as Amber and is composed of carbon, oxygen,hydrogen and a trace of sulfur. Amber, because of its organic origins is not atrue mineral.Amber in the state of Kansas is called jelinite. It is yellow to brownish in coloris clouded or translucent and has a resinous to waxy lusters. Many specimensshow a banded structure and can be scratched by a copper penny but not by thefingernail. It is brittle, breaks with a shell-like (conchoidal) fracture and is verylight in weight - only slightly heavier than water. It burns readily giving a smokyflame. Amber in Kansas has been found in lignite beds of cretaceous age, whereit occurs as rounded and irregular masses from the size of a pea to four inchesin diameter.AMPHIBOLITE - A metamorphic rock consisting chiefly of hornblende or ofsome member of the amphibole group. It is, as a rule, a synonym of hornblendeschists but is preferable to the latter when the schistosity is not marked. (Kemp)ANDESITE - A volcanic rock of porphyritic or felsitic texture whose crystallizedminerals are plagioclastic and one or more of the following: biotite, hornblendeand augite. (Kemp)ANHYDRITE - Anhydrite, which is composed of calcium sulfate (CaSo

4) is

one of the three main evaporite deposits; the other two being gypsum and halite.It occurs commonly as gray, crystalline masses, although some anhydrite has afibrous structure. It may occur as individual crystals in other rocks - particularlyin dolomite. It has a glossy luster, is translucent and is harder and heavier thangypsum, for although it can be scratched easily with a knife it cannot bescratched with the fingernail. Anhydrite may change to gypsum if water isadded as for example, at surface exposures fine-grained dolomite and anhydritelook similar but can be distinguished from one and other in that hydrochloricacid will not act on anhydrite. Some anhydrites are found in deposits of PermianAge associated with beds of gypsum, dolomite and red silt. It is also found inthe ceilings of some gypsum cavesAPLITE - A fine-grained granite consisting chiefly of quartz and feldspar.Two firms produce it from mines in Virginia. It is said to have potential marketsin the glass field.


198ARAGONITE - Aragonite has the same chemical composition as calcite(CaCo3) but it differs from calcite in having poorer cleavage and in having adifferent crystal form Its crystals commonly occur as radiating groups of fibrousor needlelike shapes- like calcite, aragonite fizzes and dissolves readily in dilutehydrochloric acid and can be scratched with a knife but not with a copper coin.This mineral, which is colorless to white, gray, yellow, green, brown, and violet,is ordinarily found as a vein mineral in cave deposits, and as the pearly layer ofmany types of shells. Aragonite is much less common than calcite because itchanges easily to calcite without altering its external shape. It is difficult toidentify in the field. The mineral has been reported in several places, as nodulesin a clay deposit, and in a sand pit, as small vugs in a quarry and in manyseptarian concretions in the cretaceous shales of Western Kansas.ARTIFICIAL SANDS - Commonly called crusher screenings, they are thefine materials produced when gravel or stone is crushed. These screenings varyconsiderably as to angularity and gradation, depending upon the type of rockcrushed, but fairly well-graded sands can be produced in this way. Most crusherscreenings range in gradation from 1⁄4 inch down to and including 0 to 6%passing the 200 mesh sieve, although in most cases they are deficient in the No.40 to No. 80 mesh size.ASBESTOS (Mineral) - A grayish or greenish variety of amphibole, occurringin long, delicate fibers, or in fibrous masses. It is noncombustible, nonconducting,and chemically resistant.ASPHALT - A complex compound of various hydrocarbons, part of which areoxygenated. Related in origin to petroleum. Is brown or brownish black in color,and is also called mineral pitch. Same as asphaltum.ASPHALT CEMENT - Refined asphalt or a combination of refined asphaltand flux, of suitable consistency for paving purposes. It has a normal penetrationof between 5 and 350.ASPHALTED CONCRETE - A mixture of asphalt cement with coarse gradedmineral aggregate. It is used in the construction of asphalt bases, binder coursesand surface courses. The most common mineral constituents of asphalticconcrete are a combination of broken stone, broken slag or gravel with sand andmineral filler, except that the mineral filler is usually left out of base and bindercourse mixtures.ASPHALT ROCK - Asphalt is a solid or nearly solid organic substancecomposed of carbon and hydrogen, which is formed when the lighter parts ofpetroleum evaporate and the heavy tarry residue remains behind. Naturalasphalt, that is made by nature and not in an oil refinery, is found in the poresof some limestone and sandstone. It occurs in rocks of the Pennsylvanian Ageand in small amounts in cretaceous sandstone. Since many porous sandstonesand limestones do not have asphalt in them, particularly where the rocks outcropand weathering has a chance to act on them. Much exploration must be done inorder to find a good deposit of asphalt rock. This is usually done by diggingsmall pits or quarries, or by drilling shallow test holes .BANK GRAVEL - Gravel found in natural deposits, usually more or lessintermixed with fine material, such as sand or clay, or combinations thereof,gravelly clay, gravelly sand, clayey gravel and sandy gravel, indicate thevarying proportions of the materials in the mixture.BANK SANDS - Sand pits containing sand with little or no gravel. This sandcontains from 0 to 12% clay and silt and has a gradation suitable for sand asphalt,a bituminous mix.


199BARITE - Barite (barium sulfate, BaSO

4) is a common mineral, but it is not

found as a rule in large quantities because of its high density. It is sometimescalled “heavy spar.” It occurs as flat tabular crystals, either singly or in groups,and it also occurs in granular or earthy forms. The individual crystals aretransparent to opaque and have a glassy luster and Perfect cleavage in twodirections.Barite is usually colorless or white, but may be light shades of blue, yellow, orred. It can be scratched with a knife, but not with the fingernail. In appearance,it resembles gypsum, calcite, or celestite. However, aside from its relativelyheavy weight, it can be distinguished from gypsum by its greater hardness andfrom calcite because it does not fizz in hydrochloric acid. A flame test is the bestmeans of distinguishing between barite and celestite. If powdered barite isheated on a clean platinum wire in a Bunsen burner, the flame will becomegreen, but celeste will turn the flame bright red.Barite is used in paint pigments, as a filler in paper and cloth, in making glazesfor pottery, and in the refining of sugar.BASALT - A word of ancient but uncertain etymology. It is employed as a rockname in its restricted sense for porphyritic and felsitic rocks consisting of augite,olivine, and plagioclase with varying amounts of glassy base which mayentirely disappear. In a broader sense the basalt or basaltic group is used toinclude all the dark, basic, volcanic rocks, such as the true basalts; thenepheline-, leucite-, and melilite-basalts; the augites and limburgites; thediabases, and melaphyres.BASE COURSE - The first or lowest course of a road, as of a foundation. Alsocalled Foundation course.BATCH - A charge placed in a pugmill of Bituminous mixing plant.BAUXITE (Mineral) - A ferruginous aluminum hydroxide, essentiallyAl

2O

32H

2O, but consisting of several minerals occurring in oolitic masses and

in earthy form. It is a nonmetallic clay mineral and has several industrialapplications.BENTONITE - Bentonite is a clay formed by chemical alteration of volcanicash. It is particularly interesting because of its properties of swelling when wateris added. It may swell to as much as 15 times its original bulk, and it forms amilky cloud in the water. Some bentonites can be identified by their waxy orsoapy appearance. Some thin deposits are interbedded with chalk and chalkyshale.BINDER - A foreign material introduced into the mineral portion of thewearing surface for the purpose of assisting the road material to retain itsintegrity under stress, as well as, perhaps, to aid in its first construction.BINDER SOIL - That material which consists primarily of fine soil particles(fine sand silt, true clay and colloids) and has good binding properties Thismaterial is commonly referred to as clay binder.BLOW SANDS - This sand is used chiefly as a blend to fill in the gradationbetween No. 40 and No. 100 mesh that may be deficient in other sands used forbituminous construction.BORAX AND BORON - The extremely versatile chemical boron is found inmany minerals, of which borax, kernite and colemanite are currently mostimportant, Boron is a nonmetallic element occurring only in combination, as inborax. (Borax—a crystalline, slightly alkaline borate of sodium, Na

2B

4O, used

as a flux, cleansing agent, antiseptic, etc.) Boron is used in glass-making,ceramics, metallurgy, soil fertilization, cosmetics, detergents, antiseptics, atomicenergy and hundreds of other industries .


200BOULDER or BOWLDER - A fragment of rock brought by natural meansfrom distance (though this notion of transportation from a distance is not alwaysin later usage, involved) and usually large and rounded in shape. Cobble stonestaken from riverbeds are, in some American localities, called bowlders.BOULDER CLAY - Boulder clay is an extremely varied deposit consisting, asthe name suggests, of particles of all sizes, from large boulders to clay. It is atypical product of glacial action and is often called glacial till. Boulder clayforms low, rounded, rolling hills covered with loess, soil and vegetation. Theboulders and pebbles, which have been carried by ice from both local and distantrocks, are of many different types. They include limestone, sandstone, quartzite,granite, basalt, and many others. Most of them have been deeply weatheredsince they were left by the melting of the ice sheet; they have been so muchweathered that a “hard granite” can be crumbled with bare hands. Upon closeexamination, some of the Pebbles and boulders are seen to be scratched andpolished from rubbing against other rocks in the ice.BRECCIA - A fragmental rock whose components are angular and therefore,as distinguished from conglomerates, are not waterworn. There are friction orfault breccias, talusbreccias and eruptive breccias. ( Kemp )BROMINE - An element, normally a deep-red caustic liquid emitting anirritating, reddish-brown, ill-smelling vapor. Responsible for “knock-free”gasoline, bromine is also used in medicine, photographic agents, dyes, chemicals,soil fumigation, etc.CALCITE - Calcite (calcium carbonate, CaCO2), is the important mineral inlimestone and is therefore, one of the most common minerals, and contains 56%lime, CaO. Generally it is white or colorless but it may be tinted gray, red, green,or blue. It occurs in many varieties of crystal forms (more than 300 have beendescribed). Calcite can be scratched by a knife, but not by the fingernail, and itfizzes freely in cold hydrochloric acid. If a large crystal of calcite is shatteredwith a hammer, it breaks into smaller rhomb-shaped blocks because it hasPerfect cleavage in three directions.Besides being the important mineral in limestone, calcite occurs as a commoncementing material in some sandstones. It is found in many calcareous shalesand clays and as veins in some igneous rocks in the cretaceous niobra chalk andother cretaceous rocks, it is found in rather large veins. Calcite is an importantpart of many concretions; brown calcite and colorless to yellow calcite crystalsare common in some septarian concretions of shale. Tiny calcite crystals formthe lining of geodes in certain Permian limestones and shales and they coat theinsides of many fossil shells. Good calcite crystals are found in some lead andzinc mines, most of these are pale yellow and some are quite large.CALICHE—1. (Mex.) Feldspar; a white clay. 2. (Mexico and Southwest U. S.)Gravel, sand, or desert debris cemented by porous calcium carbonate; also thecalcium carbonate itself.CALCIUM CHLORIDE—A crystalline compound, CaCl

2, used in its

anhydrous state as a white porous solid as a drying agent to lay dust. It is alsoused for highway ice and dust control.CELESTITE—Celestite (strontium sulfate, SrSO

4) is similar to barite in

appearance, in geologic occurrence and in crystal form. It has a glassy luster andits crystals are colorless, white, or a faint blue or red. This mineral is also foundas radiating pink fibers, as vein fillings, and as scattered particles. Celestitecannot be scratched by the fingernail, but can be scratched by a penny. It differsfrom barite in its lighter weight and in its property of coloring a flame red.Celestite has been found in solid blue crystals and as pink to white radiating


201fibers. It also has been found as pink crystals and as veins and has been foundat the top of Permian Rocks below cretaceous sands and shales.CERUSSITE—Cerussite (lead carbonate, (PbCO

2) occurs as granular masses

and as platy crystals which commonly cross each other to form a lattice-likeeffect. Cerussite has a brilliant, glassy luster, is colorless or white and can bescratched by a penny but not by the fingernail. It fizzes in cold hydrochloric acidand is very heavy for a nonmetallic mineral. Small amounts of cerussite areoccasionally found as a result of the chemical change of galena (lead sulfide) inthe near surface parts of lead deposits.CHALCOPYRITE - An important ore of copper where it occurs in abundance,chalcopyrite or copper pyrite is a sulfide of copper and iron (CuFeS2). It is abrassy yellow mineral that makes a greenish black streak and has a brightmetallic luster. It is brittle, may be tarnished, can be scratched by a knife but notby a penny. It occurs normally as four sided pyramid-like crystals but thecrystals are usually poorly formed when the mineral occurs as massive sulfideore. Chalcopyrite is very similar in appearance to pyrite, but is softer than pyrite(pyrite cannot be scratched by a knife) and it has a greenish sheen which pyritedoes not have. Chalcopyrite is sometimes found with dolomite crystals and withlead and zinc ores and is sometimes associated with barite.CHATS - (Northumb) Small pieces of stone with ore. (Eng.) A low grade oflead ore. Also middlings which are to be crushed and subjected to furthertreatment. The mineral and rocks mixed together which must be crushed andcleaned before sold as mineral. Chats are not the same as tailings, as the latterare not thrown aside to keep for future milling.CHERT - A compact, siliceous rock formed of chalcedonic or opaline silica,one or both, and of organic or precipitated origin. Chert occurs distributedthrough limestone, affording cherty limestones. Flint is a variety of chert. Chertis especially common in the Carboniferous rocks of southwest Missouri. Seealso Hornstone.CHIPS - 100% fractured stone usually passing 1⁄2-inch square mesh sieve butretained on No. 8 sieve. Applied over seal coats, broomed and rolled to providea skidproof surface and to prevent bleeding on bituminous roads.CLAY - An earth material of extremely fine texture, smaller than .005millimeters in Particle size, and is plastic and swells when wet. Pure clay is nota good stabilizing agent because of its plasticity index.CLOSED CYCLE SYSTEM - A series of conveyors and/or elevating deviceswhich return oversize material back to a crusher for further reduction.COAL LIGNITE - Lignite ranges in appearance from a light brown to a darkbrown, compact, dull, earthy mass to a bright, black, banded mass, and it yieldsa brown powder when ground or when rubbed over a rough white surface. AsAmerican lignite comes from the mine, it contains 30 to 40% moisture. Whenexposed to the air, it soon slacks or falls to pieces because of loss of moisture.If it is not stored properly, it will take fire spontaneously. Although there arethousands of square miles of lignite deposits in the United States, production ofthis rank of coal is not yet important nationally. It is difficult to store and itsheating value is low, making it uneconomical to ship very far. However, lignitecan be dried, briquetted or made into gas suitable for the reduction of iron ore,the production of synthetic liquid fuels and other uses.SUB BITUMINOUS COAL - Sub-bituminous coal is black; and as it is mined,it looks a great deal like the bituminous coal seen in coal yards. It contains from15 to 30 % moisture. The range of heating value of sub-bituminous “A” coal isthe same as that of high volatile “C” bituminous coal. Sub-bituminous coal is


202entirely non-coking. Like lignite, it weathers or slacks rapidly upon exposure toair and is subject to spontaneous combustion if not stored properly. Because ofthe same disadvantageous features as lignite, it is used principally in the areaswhere it is mined.BITUMINOUS COAL - Bituminous coal is the most abundant and widespreadrank of coal in the United States. It is the coal used most commonly forindustrial, power, railroad, and heating purposes. Bituminous coal may beeither coking or non-coking. This property is not based on the rank of the coal,but rather on whether it will produce a coke when Processed in a coke oven.Nearly all eastern bituminous coals have coking properties, but many of thewestern bituminous coals are non-coking or free burning.A coking, or, as it is sometimes called, caking coal is one that softens and runstogether when it becomes almost hot enough to take fire. As it is heated further,some degradation of coal substance occurs, and the volatile matter escapes asa gas. When the coal is heated red hot in a sealed oven where there is little or noair, a dull gray porous mass called coke remains after the volatile liquids andgases have been driven off. Because coke consists largely of fixed carbon, thecoking process is often called “carbonization.” Coke and the gases liberatedhave many important uses.Most bituminous coals appear black and lustrous in the pile: but, if you look atthem closely, you will observe a banded structure with alternate layers of bright,glossy coal and of dull grayish black coal. In some coals, this dull materialpredominates and these coals have a dull grayish black appearance.ANTHRACITE - Anthracite, sometimes called hard coal, has a brilliant lusterand a uniform texture. If you handle anthracite, it will not soil your fingers asdoes coal of lower ranks. Anthracite has a higher Percentage of fixed carbon anda lower percentage of volatile matter than the lower rank coals. It burns slowlywith a pale blue flame free from smoke. Most anthracite has a somewhat lowerheating value than the highest grade bituminous coals, but its lack of soot andthe fact that it will burn longer without attention make anthracite an idealdomestic fuel.COMMON BANDED COAL - Common banded coal, sometimes calledbright coal, is the variety that includes most coals. It is composed of bothanthraxylon and attritus in varying proportion and has a bright luster.SPLINT COALS - Splint coals are composed almost wholly of attritus, withonly a little anthraxylon. The coal is a dull grayish black and is hard and tough.When mined, it breaks into block lumps because of this characteristic, it is called“block coal” in some mining regions. Splint coal is good for steam power plants.When heated, it is inclined to splinter and makes a better coke when used inblends with banded coal.CANNEL COAL - Cannel coals are made up entirely of attritus, often rich inspores. Spores are the reproductive organs of the lower plants that do notproduce seeds. Cannel coals are often rich in volatile matter and burn with a longyellow flame. They used to be called “candle” coals because of the appearanceof the flame and because many of them can be lighted with a match or a pieceof burning paper. It usually occurs in small lenses or deposits in beds of othercoals and must be separated from the other coal during mining. In the originalcoal swamps, the spore and seed case of plants and finely divided particles ofwoody material floated upon the open water until they became waterlogged,sank to the bottom and finally changed into cannel coal.BOGHEAD COAL - Boghead coal is a variety of bituminous or subbituminouscoal that looks and burns much like cannel coal. It is made up largely of theremains of algae water plants that form the greenish or brownish scum you often


203see on fresh water ponds and reservoirs in summer and fall. It is rich in volatilehydrocarbons that produce illuminating gas. When distilled, it yields a greatdeal of tar and oil. Like cannel coal, it is usually found in small deposits orlenses.CORAL - The solid secretion of coral polyps, composed almost wholly ofcalcium carbonate, which forms reefs and treelike and globular masses.CONGLOMERATE - An aggregate of rounded and water-worn pebbles andbowlders cemented together into a coherent rock. Deposited by streams orwaves, generally with some sorting and stratification. Compare Breccia.Conglomerate is a hardened, generally cemented gravel, and like sand, silt, andclay, has been formed by the breaking down of older rocks and by later re-disposition. Commonly it is found interbedded with layers of sandstone. It alsooccurs at the base of many Pennsylvanian formations. Conglomerate and gravelare used in making concrete, in surfacing roads and as railroad ballast.CONVEYORS - A device consisting of a steel frame equipped with rollers andpulleys over which a continuous rubber belt travels and used for delivery ofmaterial from one portion of a plant to another. Note: Conveyors are furtherdescribed by a word describing their use i.e., a “feed” conveyor usually feedsmaterial into a plant, crusher or on to a screen, A “delivery” conveyor usuallydelivers material from any of components to another component, or to a truckor stockpile.DIABASE - A basic igneous rock usually occurring in dikes or intrusive sheets,and composed essentially of plagioclase feldspar and augite with small quantitiesof magnetite and apatite. The plagioclase forms lath-shaped crystals lying in alldirections among the dark irregular augite grains, giving rise to the peculiardiabasic or ophitic texture, which is a distinctive feature in the coarser-grainedoccurrences (U. S. Geol. Surv.). Diabase is often used as a prefix for doublenames, as diabase-aphanite, diabase-gabbro, etc . ( Kemp )DIORITE - A granitoid rock composed essentially of hornblende and feldsparwhich is mostly or wholly plagioclase, with accessory biotite and (or) augite.Minute grains of magnetic and titanite may be visible. Quartz may be presentin considerable amount, in which case the rock is called quartz diorite. Quartzdiorites grade into tonalites and granodiorites. (U. S. Geol. Surv. )DOLOMITE - Dolomites are fine to coarse grained rocks which in the purestate are light colored. On weathering, they tend to become buff or tan becauseof impurities which consist commonly of small amounts of pyrite, siderite, ormarcasite or of iron in the dolomite crystals. Dolomites may be formed muchas limestones are formed; for example, by chemical precipitation, or by theaction of waves and streams on older dolomites. They are also converted fromlimestone by a process appropriately called dolomitization. This involves thereplacement of calcium by magnesium or the solution and removal of thecalcium carbonate. The change may take place before or after the rock has beensolidified, and is caused by the action of sea water, ground water, or hot mineralwater. Dolomite is used in most of the ways that limestone may be employedand in addition, it is a possible source of magnesium. The mineral dolomite iscomposed of calcium magnesium carbonate (CaMg(CO

3)

2) and is closely

related to calcite. In large masses, the mineral forms the rock called dolomite.It may be white, gray, greenish gray, brown, or pink, and has a glassy to pearlyluster. It occurs in coarse to fine grained granular masses and in crystals. Mostdolomite crystals are rhomb-shaped like calcite cleavage blocks, but unlikemost other minerals, the crystal faces are typically curved. Dolomite is slightlyharder than calcite, although it can be easily scratched by a knife. It will not fizzin cold hydrochloric acid unless first ground to a powder or the acid heated.


204EPSOMITE - Epsom salts are recovered from lake bed deposits or by chemicaltreatment of rocks such as dolomite or talc that contain magnesite. Washingtonis the major producer, having several lake deposits. Medicinals use the purifiedchemical grade, while the technical grade goes into fertilizers, enamels, paintsand soaps.EVAPORITES - Rocks formed by the evaporation of water are known asevaporites. This evaporation may take place either in shallow basins on the landor in the sea, however, the rocks which were laid down under the sea form thethicker and more widespread deposits. Rocks formed in this way includedeposits of gypsum, anhydrite, and common salt or halite. Sea water containsmany salts in solution. These are brought into the ocean by rivers which arecontinually wearing down or eroding the land surfaces, and dissolving the salts.When the sea water evaporates, the salts settle to the bottom. The less soluble—those that dissolve less readily in water—are deposited first during the evaporationprocess. Calcium sulphate, the compound that forms gypsum and anhydrite, isamong the least soluble and consequently is one of the first deposited afterdolomite. Next in order of solubility and hence deposition is sodium chloride orcommon table salt. Evaporite deposits are described more fully under theseparate mineral names gypsum, anhydrite, and halite. The evaporites formedon the land are neither so thick nor so common as those formed under the sea.FEEDER - A device placed under a hopper which conveys material into a plant,crusher or onto a conveyor at a uniform rate.

The feldspars are light in color (pink, green,white, and gray), have a glassy or satiny luster and have a good cleavage in twodirections, almost at right angles to each other. They cannot be scratched by aknife. Most feldspars occur in igneous rocks. Feldspar pebbles may bedistinguished from quartz pebbles by the good cleavage.FILLER - Relatively fine material used to fill the voids in aggregate .FINE GRADE AGGREGATES - Material which will pass a No. 10 meshscreen and retained on No. 200.FINISHED PRODUCT - The resultant material after it has been processed(crushed, screened, sometimes washed) to the desired size and specifications.FIRE CLAY - Clay capable of enduring high heat without fusing, and henceused for firebrick.FLUORSPAR: FLUORITE - The mineral calcium fluoride, CaF

They have a glassy luster and are hard enough to scratchwindow glass. Most garnets are red to brown, but some are black, green, orcolorless. In chemical composition, they are silicates of calcium, magnesium,iron, manganese, aluminum, and chromium in various combinations, thealuminum silicate varieties predominating.GNEISS - A layered crystalline rock with a more or less well developedcleavage, but without the fissility of schist. (U. S. Geol. Surv.) The commonestvarieties are mica-gneiss, consisting of feldspar, quartz, and mica; andhornblende-gneiss, consisting of feldspar, quartz, and hornblende.GLOSLARITE - Gloslarite (ZnSO

47H

2O) is zinc sulphate containing water

and is formed by chemical action on sphalerite. It is sometimes found as long,slender, needle-like crystals.GRADED AGGREGATE - A term describing a mineral aggregate in whichthere is a continuous grading in the sizes of mineral fragments from coarse tofine, the coarser sizes being many times the diameter of the finer sizes.GRANITE - A granular igneous rock composed essentially of quartz, orthoclaseor microcline, and mica. Commonly a part of the feldspar is plagioclase. Themica may be either biotite or muscovite or both. Hornblende is a common andaugite an uncommon component. Apatite, zircon, and magnetite are alwayspresent, generally as very small portions. Commercially, almost all compactigneous rocks are called granite as distinguished from slate, sandstone, andmarble.GRAVEL - Small stones and pebbles or a mixture of sand and small stones;more specifically, fragments of rock worn by the action of air and water, largerand coarser than sand.GRAVEL - The term gravel, used loosely, usually means a rock composed ofparticles ranging from sand to pebble size or larger (2 to 64 mm). Graveldeposits vary greatly in mineral composition, size, shape, and color. There aregravels which consist mainly of just one mineral, as chert or flint weatheredfrom the Pennsylvanian and Permian Rocks, or feldspar, agate, clear transparentquartz, native copper, granite, basalt (a fine grained rock ) and other igneousrocks.GRAVEL PIT SANDS - Produced by separating sand (material passing No.4 sieve) from gravel with a mechanical screen. This type of sand sometimescontains quantities of clay and has a fairly complete gradation ranging fromcoarse to very fine.GREENSAND - A sedimentary deposit consisting of dark greenish grains ofglauconite, often mingled with clay or sand. It is primarily used for watersoftening and purification. Also, agricultural use is a new development.GRIT - 1. In petrology, a sandstone composed of coarse, angular grains andvery small pebbles. 2. An artificial stone for sharpening tools. Standard gradesare coarse, medium and fine. Coarse stones cut very readily, but leave a roughedge. Medium stones do not cut as fast as coarse stones but leave a smootheredge. Fine stones are still slower cutting, but are useful where extremely fineedges are desired. 3. Rough, hard particles; sand or gravel. 4. Degree ofhardness with openness of texture or composition; allied to buhrstone and thelike.

Some crystals are 3 or 4 feet long andclear throughout .HEMATITE - Hematite is a compound of iron and oxygen (Fe2O3) which maybe either red or earthy or black with a dull or metallic luster. Both types have ared-brown or Indian-red streak by which the mineral is readily identified. Theearthy variety marks paper easily.HEMIMORPHlTE - Hemimorphite, sometimes called calamine is a silicateof zinc containing water. Its chemical formula can be written H

2ZnSiO

2. It is a

white mineral which is found in radiating crystal groups and in globular forms.Its hardness is such that it can be scratched by a knife but not by a Penny.Hemimorphite usually occurs with zinc ores.HORNBLENDITE - A granitoid, igneous rock, consisting essentially ofhornblende and analogous to pyroxenite. (Kemp)HORNSTONE: CHERT - An impure flint or chalcedony with splinteryfracture, more brittle than flint.ILMENITE - Ilmenite is an iron black mineral composed of iron, titanium, andoxygen (FeTiO

3). It makes a brownish-black streak and it cannot be scratched

by a knife. Most large specimens of ilmenite are dense, granular masses, but themineral may occur as platy crystals and as grains in sand. Where ilmenite ismined as an ore, as in New York State, it is desired for its titanium content. Thetitanium, as the oxide, is used in paint manufacture.JASPEROID - Jasperoid is metamorphosed sedimentary rock in which thelead and zinc ores of the Tri-State mining area of Kansas are commonly found.A gray to black mottled chert, coarser grained than ordinary chert, it is thecementing material around angular pieces of the original light-colored brokenchert.JAW CRUSHER - A crusher which breaks material by squeezing it betweentwo jaw plates, one movable and one stationary.KAOLIN - A very pure white clay, used to form the paste of porcelain.

Mined commercially inVirginia and Carolina.LAKE OR BEACH SANDS - Fine granular sand composed chiefly of round,smooth particles, and are usually blended with coarse sands to complete thegradation for bituminous construction.LAVA ROCK - When volcanoes erupt quietly instead of explosively, moltenrock pours out in a thick liquid state. The solidified material formed by coolingof the lava commonly has a ropy appearance; it is a dark fine-grained rock calledlava rock. Boulders and pebbles of lava rock occur in stream deposits and inboulder clay and related deposits of some glaciated regions.LIME - An alkaline earth consisting of the oxide of calcium. Artificially madeby cabining or burning limestone or marble. Lime made from dolomiticlimestone contains a considerable percentage of magnesia and is slower setting.LIME ROCK - Any rock or stratum in which limestone is a prominentingredient. Limestone.


207LIMESTONE - The general name for sedimentary rocks composed essentiallyof calcium carbonate.LIMESTONE & DOLOMITE - Limestone and Dolomite are two veryclosely related rocks. The former, in a pure state, consists of grains of themineral calcite and the latter of grains of the mineral dolomite. To be scientificallycorrect, the term dolomite should be used only when speaking of the mineral,but through common usage dolomite as a rock is now generally accepted.Calcite consists of calcium carbonate and is one of the most common mineralsknown. The mineral dolomite is made of calcium magnesium carbonate and isalso quite common. These two minerals are often found together in the samedeposits and whether the rock is classed as a limestone, a dolomitic limestone,or a dolomite depends on the proportion of each mineral. The two minerals canbe told apart by the way hydrochloric acid reacts on each. Cold dilute hydrochloricacid will fizz when it is put on limestone; in order to react in the same mannerwith dolomite, either the dolomite must be powdered or the hydrochloric acidmust be heated. Pure limestones are white or almost white. Because ofimpurities such as clay, sand, organic remains iron, and other materials, manylimestones exhibit different colors, especially on weathered surfaces. Limestonesmay be crystalline or granular depending on the method of formation andcrystals of calcite, quartz, or dolomite may line small cavities or geodes in therock. Chert balls or nodules are common in limestone layers.LIMONITE - Limonite, a compound of iron, oxygen and water (2Fe

2O

3-3H

2O)

is a yellowish-brown to dark brown or black noncrystalline mineral. It is formedby the alteration of other minerals that contain iron. Limonite has a characteristicyellow-brown streak but its hardness depends on the form in which it occurs.The yellow-brown earthy form of limonite, really a mixture of limonite andclay. Called yellow ochre, is so soft that it easily leaves a mark on paper. Thedark brown to black variety (bog iron ore) is so hard it cannot be scratched bya knife. Small quantities of limonite give a yellowish or buff color to mostsandstones and to many clays, shales, and limestone. As a scum on quiet water,it may be mistaken for oil. It is an iron ore of minor importance in some states.LITHIUM (Chem.) - A soft silver-white metallic element. Spodumene isrecovered in North Carolina. South Dakota and Maine. Crude sodium lithiumphosphate is produced in California. Amblygonite is mined in South Dakota andlepidolite in New Mexico. Other lithium minerals are under investigation. It isused for lithium greases, ceramics, porcelain elements and glass.LOESS - In geology, a yellowish, fine-grained, slightly calcareous, loamy clay,commonly unstratified but having same vertical jointing, believed to be adeposit of wind-blown dust. (La Forge. )LACNESITE - Native magnesium carbonate, MgCO

3. Purities range from 82

to 96% MgO. Domestic supply is deemed sufficient for the normal needs of thesteel, metallurgical and miscellaneous refractory trades, which use magnesitein the form of grain, mortars, ramming mixes and brick. Brinedolomite andother brine magnesite production now totals about half the national potential.Calcined magnesite products are used for insulation, chemical, building andfertilizer purposedMAGNETITE - Magnetite (iron oxide Fe3O4) is so named because it is readilyattracted by a weak magnet and because some magnetic specimens calledlodesterres are, in themselves, magnets. The mineral is black, has metallic lusterand makes a black streak. It is so hard that it cannot be scratched by a knife. Itis found as granular masses, but especially in igneous rocks, it commonly occursas individual crystals, most of which have eight triangular faces and are called


208octahedrons. Magnetite is an important ore of iron. Occasional grains ofmagnetite may be found in many river sands.MARBLE - In lithology, a metamorphosed and recrystallized limestone. In thetrade, the name is applied to any limestone that will take a polish. The followingare some of the principal marbles: Bardiglio, bird’s eye, black and gold,boagard, breccia, calico, campan, cipolino, eolian, fior di persicor, fire, forestgriotte, landscape, lumachelle, mischio, nero antico de prato onyx, porter, rossoantico, ruin, St. Anne, St. Baume, stalactitic and stalagmitic statuary, verdantiqueand winooski.MARCASITE - Marcasite, sometimes called white iron pyrite, is a mineralcomposed like pyrite or iron sulfide (FeS2). On fresh surfaces, it is pale yellowto almost white and has a bright metallic luster, it tarnishes to a yellowish orbrownish color and gives a black streak. It is a brittle mineral which cannot bescratched by a knife. The thin, flat tabular crystals when joined in groups arecalled “cockscombs". When combined into balls or nodules, or into morecomplicated groups, they make marcasite rosettes. The mineral can bedistinguished from pyrite by its lighter color and by its crystal form. Marcasiteweathers readily to form limonite and melanterite.MASTIC - A mixture of bituminous material and fine mineral matter suitablymade for use in highway construction and for application in a heated condition.MEERSCHAUM - Also called sepiolite, this lightweight white clay mineralis used mostly in making smokers requisites, pipes, etc. There are scattereddeposits in the United States. It has potential use as electrical insulation,toothpaste, oil absorbent, etc.MELANTERITE - Melanterite, or copperas, is a sulfate of iron with water(FeSO4-7H2O) occurring as very fine, fibrous masses that are hard to preserve.It is greenish-white to white and has a sweet, metallic, bitter taste. It is formedby chemical action on pyrite or marcasite under damp conditions, such as on thewalls of underground mines and in coal seams.MICA - Mica is the name of a group of several minerals which are unusualbecause they split into thin, flat, flexible, or elastic sheets. The type of splittingis due to the fact that micas have one perfect cleavage. They are composed ofaluminum silicates of many elements. Muscovite, or common “white” mica, istransparent and colorless. It can be seen as tiny, flat shining flakes in sandstones,siltstones, and shales, and as small crystals in boulders of metamorphic andigneous rocks. Biotite (black mica) may be seen in some tertiary and quaternarysands. The color of biotite is caused by iron. Phlogopite mica is yellowish-brown, has a copper-like luster on the cleavage surface and often is mistaken forflakes of gold.MINERAL DUST - A finely powdered rock dust, Portland Cement, or otherartificially or naturally powdered mineral dust, 80 to 100% of which will passa No. 200 mesh sieve.MINERAL EARTH PIGMENTS - Pigments used in paints follow closely theconstruction picture in production. The natural mineral iron-oxide group,prepared for market by washing, drying, grinding blending and calcining,account for 55% of the total. Chemically manufactured iron-oxide pigments(referred to as pure or synthetic), produced by calcination or controlledoxidation, make up the rest.MINERAL-FILLED ASPHALT - Asphalt cement containing an appreciablepercentage (usually between 10 and 50% by weight) of very finely dividedmineral matter passing the 200 mesa sieve.HARDNESS OF MINERALS - Some minerals are very soft; others are veryhard. The degree of hardness is an aid in identifying the minerals. Diamonds are


209harder than quartz and will therefore, scratch quartz; quartz will scratch calcite;calcite will scratch gypsum and so on. An easy way of estimating the hardnessof a mineral in the field is by trying to scratch it with such common objects asa fingernail, a copper penny, a pocket knife blade, and a piece of window glass.Glass the hardest of the four, will scratch the most minerals, the knife is next inhardness; then in order comes the copper cent, and the fingernail.CLEAVAGE AND FRACTURE OF MINERALS - Some minerals whenstruck a sharp blow, break only along certain lines, while other minerals breakjust as easily in one direction as in another. When a mineral has a tendency tobreak along certain planes, it is said to have Cleavage, which is the result of thearrangement of the molecules and atoms. Minerals may have only one plane ofweakness or cleavage, or they may have two, three, or more. The second typeof breaking, that which is not determined by any arrangement of molecules iscalled fracture and this also varies among different minerals. Various types offractules are described as smooth, uneven, ragged, and shell like .MINERAL WOOL - Produced from rock, slag and glass, this insulatingmaterial has been growing in use. Major fields of use include structuralinsulation, equipment insulation and industrial insulation.NEPHELINE SYENITE - This quartz-free crystalline rock consisting mostlyof nephelite, albite and microcline feldspar is found in New Jersey, Arkansasand other states, but usually has too much iron for ceramic purposes,OBSIDIAN - 1. Extrusive igneous rocks which have cooled either withoutcrystallization or with only partial crystallization. (U. S. Geol. Surv.) 2. Ageneral name for volcanic glass. When used alone it implies a rhyolite-glass, butit is now much employed with a prefix as andesite-obsidian, basalt-obsidian.(Kemp)OLIVINE - Comprising fayalite, olivine and forsterite, this mineral group isfound in many rocks. Large concentrations, called “dunite,” are mined orquarried commercially in North Carolina and Washington to make refractorybrick and cements and foundry sand.OOLITE - A rock consisting of small round grains, usually carbonate of lime,cemented together.OPAL - Opal consists of silicon dioxide, like quartz, plus an indefinite amountof water (SiO

2-nH

2O). It never forms as crystals, but probably is deposited as

a jelly-like substance which later hardens. The mineral may be white, yellow,red, brown, green, gray, blue, or transparent and colorless. Precious opal showsa beautiful display of colors and is highly prized as a gem stone. Opal cannot bescratched by a knife, but is slightly softer than quartz. It is found as a lining orfilling in cavities in some rocks, as a deposit formed by many hot springs, andas the petrifying material in much fossil wood.OVERBURDEN - The waste which overlies the good stone in a quarry,Worthless surface material covering a body of useful mineral .OVERSIZE - Material which will not pass a desired size of square openingscreen wire and therefore must be crushed or recrushed .PEA GRAVEL - Any clean gravel, whether bank or river gravel, having agradation of from 1⁄4 to 1⁄2-inch or which approximate a pea in grain size.PEAT - Semi-carbonized vegetable tissue formed by partial decomposition inwater of various plants, asp. mosses of the genus Sphagnum. Used in thiscountry for soil improvement and mixed fertilizers.PEBBLES - 1.

210PERIDOTITE - A granular igneous rock composed essentially of olivine,generally with some form of pyroxene, and with or without hornblende, biotite,chromite, garnet, etc. (La Forge)PERLITE - 1. Volcanic glass with concentric, shelly texture and usually witha notable percentage of water. 2. Also called Pearlite or Pearlstone. A eutectoidof cementite and crystallized iron formed by slow cooling of molten steel.PHOSPHATE ROCK - A rock consisting of calcium phosphate, usuallytogether with calcium carbonate and other minerals, used in making fertilizers.PSILOMELANE - Psilomelane is an oxide of manganese (MnO

2). It is a black

mineral that makes a very dark brown to black streak, is much harder thanpyrolusite it cannot be scratched by a knife. An earthy form of psilomeiane,however, is known as wad, and it is soft enough to soil the fingers. Wad formsthe coating around some pebbles in gravel deposits, and it also occurs as softblack lumps in gravels.PUMICE - An excessively cellular, glassy lava, generally of the compositionof rhyolite (Kemp). A sort of volcanic froth. Its color is generally whitish or lightgray. It is very light and will float on water. Pumice stone.PYRITE - Pyrite (iron sulfide, FeS

2) is a pale, brass yellow, opaque mineral that

is brittle and has a metallic luster. It makes a black streak and is so hard that itcan scratch glass. Many pyrite crystals are cube shaped like galena, but they alsooccur in other forms. Pyrite is also found as granular masses, as cones andglobules, and as nodules in shale, limestone and sandstone. It is called “fool’sgold” because it is yellow but pyrite is brittle, has a greenish tinge, and tarnishes,whereas gold is softer, leaves a yellow streak instead of a black one, and doesnot tarnish easily. Pyrite occurs in rocks of all ages and is abundant in some coaldeposits and veins. It is also found with gypsum in the dark shades. It is producedas a by-product of coal near Pittsburgh and is used in making sulfuric acid.QUARTZ - Quartz, the most common of all minerals, is composed of siliconand oxygen ( SiO2) and is found in many different varieties. When pure, it iscolorless but it also assumes various shades of yellow, pink, purple, brown,green, blue, or gray. One of the hardest of minerals, it will easily scratch windowglass. It has no good cleavage and has a glassy to greasy luster. There are twomain types of quartz, the coarsely crystalline and the fine or cryptocrystallineforms. The crystals of the first type are six sided Prisms with pyramids cappingone or both ends. Well-formed, colorless quartz crystals of this type are foundin geodes and as linings on the inside of some fossils. Quartz crystals with abluish cast are found in some granites. Nearly all sands and sandstones arecomposed of tiny worn particles of crystalline quartz. The second main type ofquartz is called cryptocrystalline because the crystals are so small that theycannot be seen without a microscope. One of the best known varieties in thisgroup is flint or chert. Chert is dull gray, brown, or black. It breaks with ashell-like fracture and the edges of the broken pieces are sharp. Chalcedony isa cryptocrystalline quartz with a waxy luster that forms banded layer s orglobular masses. Agate is a many-colored form of Chalcedony which has beendeposited in cavities or veins.QUARTZITE - Quartzite is a rock consisting of quartz sandstone so thoroughlycemented with silica that the rock breaks through the grains as easily as aroundthem. It is distinguished from sandstone not only because it breaks through thegrains, but also because it cannot be scratched with a knife. Quartzites may beeither metamorphic or sedimentary in origin and the two types are so similar inappearance that in many cases they cannot be told apart. Metamorphicquartzites are caused by intense folding of the rock or by solutions from nearby


211igneous intrusions or both. Quartzite boulders are common in the boulder clayof the glaciated area. The rock making up these boulders is red, brownish-red,or purple, and it breaks with a splintery fracture. Quartzite, because it is so hardand resistant, can be used as a railroad ballast and in the construction of dams.It is used in some places as road material and as building stone.RIVER GRAVEL - Found in almost any stream or river and consists of partlyrounded and smooth fragments of rock intermixed with river sand and is usuallyfree from clay and silt. That part, consisting of particles larger than 1⁄4-inch isclassified as river gravel.RIVER SAND - Due to action of water and the rolling of one particle of sandover another, does not have a high percentage of sharp angular grains and isusually free from clay and very fine sizes.RHYOLITE - A felsophyric to vitreous igneous rock composed essentially ofquartz and alkali feldspar, or of rock glass having substantially the samecomposition, with or without biotite, hornblende, or pyroxene; liparite. (LaForge). Rhyolite is current in America, whereas liparite and quartz-trachyte aremore used abroad. A lava, usually of light color, corresponding in chemicalcomposition to granite. The same molten liquid that at great depth within theearth solidifies as granite would, if it flowed out on the surface, cool morequickly and crystallize less completely as rhyolite. (Ransome)ROLL CRUSHER (Double) - A crusher which breaks material by squeezingit between two revolving metal cylinders, with axes parallel to each other andseparated by a space equal to the desired size of finished product.SALINES - Chemical salts in their natural state are recovered by mining, brinesaturation and other methods. A score or more types of sodium compounds existin minerals, some mined in large quantities. See boron, bromine, calciumchloride, salt, sodium compounds, magnetite, etc.SALT (Sodium chloride NaCl) - Any of a class of compounds formed when theacid hydrogen of an acid is partly or wholly replaced by a metal or a metal-likeradical.SANDS & SANDSTONES - Sands are loose, unconsolidated rocks havingparticle sizes between those of silt and pebbles (1/16 to 12mm). When heldtogether by chemical cement or by clay, they are called sandstones. These rocksresult from the breaking down or weathering of older rocks, and from thetransportation and sorting of the rock fragments by moving water or by wind.Sand mostly consists of grains of quartz, but some of it may contain largeamounts of feldspar. Sand occurs almost everywhere along large streamvalleys, in regions of old glacial drainage or out wash. Sandstones, like sand,consist largely of quartz grains, but sandstones are held together by some naturalcement or matrix such as calcium carbonate, iron oxide, or clay, and the rockscan be classified according to the type of cement. Interesting collections ofsandstones in which the grains are cemented by different types of material havebeen made. In places, sandstones occurs interbedded with shale and limestone,in other places, it occurs as channel deposits cutting through shale andlimestone. Sandstone that is buff or brownish in color is cemented with ironoxide. There are areas of sandstone cemented by calcite (calcium carbonate) incrystals so large that wide areas of the rock reflect light in a manner known as“luster mottling.” This rock is sometimes called “quartzite” because it is veryhard, but it is not a true quartzite. In other areas, soft, crumbly sandstones fromthe cretaceous age form cliffs and box canyons.SAND CLAY - (Road Surface) A surface composed of a mixture of sand andclay where the two materials have been blended, so that their opposite qualitiestend to maintain a condition of stability, under varying moisture content. Some


212deposits are found in nature, but the bulk of such surfaces are preparedartificially.SANDSTONE - An indurated sedimentary rock formed of coherent or cementedsand. The following are common varieties: Asphaltic sandstone, Bluestone,Brownstone, Building sandstone, Flagstone, and Freestone.SCALPING SCREEN - A vibrating or revolving screen which separatesvarious sizes of materials for delivery to one or more crushers and bypassessmall sizes around the crushers.SERPENTINE - 1. In mineralogy, a hydrous magnesium silicate (H

4Mg

3Si

2O

2),

commonly green, greenish-yellow, or greenish-gray, and massive, fibrous,lamellar, or occurring as pseudomorphs. It is an important constituent of somemetamorphic rocks and is everywhere secondary, after olivine, amphibole,pyroxene, etc. 2. In petrology, a metamorphic rock composed chiefly or whollyof the mineral serpentine. (La Forge)SCHIST - A crystalline rock that can be readily split or cleaved because ofhaving a foliated or parallel structure, generally secondary and developed byshearing and recrystallization under pressure. (La Forge)SCREENINGS - Fine material that passes through a screen when screening forlump material.SHALE - A hardened, compacted clay or silt which breaks along beddingplanes is called shale. The particles that make up a shale are too small to be seenwithout a microscope. Shales have a leaflike bedding and weather into thin slabsor plates some of which are no thicker than paper. When shales weather, theyform clays or muds. Shales and clays are easily eroded or worn away.Consequently the best exposures are found underneath ledges of harder, moreresistant rocks such as limestones and sandstones. Most shales are soft enoughto be cut with a knife and are rather brittle or crumbly. The usual color is gray,but black, green, red, or buff shales are common. Many shales contain nodulesof pyrite, selenite crystals, or in concretions of various forms. Shale and claytogether make up about 80% of the sedimentary rocks of the earth’s crust. Someblack, very thin bedded shales are often called slate because they have the samecolor as many slates and because they break into thin, hard platy sheets. Slate,however, is a metamorphic rock formed when shale is Put under great heat andpressure.SHELL - The term “Shell Aggregate” applies to oyster, clam shells, etc., usedfor road surfacing material. These shells are crushed in an ordinary stonecrusher. It is difficult to crush this material to a given specification, and it doesnot produce a strong pavement unless a suitable gradation is produced throughthe introduction of other aggregates, such as sand and stone.SIDERITE - Siderite which is a common mineral, is composed of ironcarbonate (FeCO2). It is light to dark brown, and some of it occurs as rhomb-shapedcrystals with curved faces (like dolomite). Most siderite, is granular or earthy.The mineral cannot be scratched by a penny, but can be scratched by a knife. Itfizzes in hot hydrochloric acid, but reacts slowly in cold acid. Weatheredsurfaces change to limonite and turn dark brown.SILICA - An oxide of silicon. (SiO

2). Occurs in nature as a mineral of economic

importance in quartz, chalcedony, chert, flint, opal, diatomaceous earth andsandstone. The most abundant constituent of the earth’s crust. See also Agate,Quartz. Also known as silex, and used for lining tube mills.SILT AND SILTSTONE - Silt is a common sedimentary rock composed oftiny particles smaller than sand size, yet larger than clay size (1⁄16 to 1⁄256 mm).It is found in stream deposits and lake beds, but it occurs chiefly as a wind blown


213deposit called loess. It is typically a yellowish buff porous silt that crops out withsteep faces along hillsides and valley walls. Much loess contains white or creamcolored concretions an inch or two in diameters which are composed of calciumcarbonate and have been caned Kindehen (little children) of the loess. Smallwhite shells of snails may also be found in the loess.Some of the finest and thickest soils in the world are formed in the upper partof thick deposits of loess. As wind moves small Particles only, a soil built upfrom deposits of this kind is free from rocks and large pebbles. Loess depositshave been built up by successive dust storms. Consolidated or compacted siltis known as siltstone. This rock may be found as thin, flabby beds in many ofthe Pennsylvanian formations. Many siltstones and fine sandstones containlayers rich in tiny flakes of mica, which glitter in the sun. The mica isconcentrated along the bedding planes where the rock breaks easily.SIZING SCREEN - A vibrating or revolving screen which separates varioussizes of materials for delivery as finished products into hoppers, trucks or ontoconveyors.SLAG - A by-product of blast furnace operation. A good quality slag makes anexcellent paving material and can be crushed into almost any gradation,although most slags are quite porous.SLATES - A dense, fine-textured metamorphic rock whose separate mineralsare indistinguishable to the unaided eye, and which has an excellent parallelcleavage, so that it breaks into thin plates or pencil-like shapes. A coal miner’sterm for any shale or slate accompanying coat also sometimes applied to bonycoal.SMITHSONITE - Smithsonite (zinc carbonate, ZnCO

3), is commonly brown

in color, but it may be green, blue, pink, or white. Although, it does occur asrough, curved, rhomb-shaped crystals, its occurrence as rounded, globularforms or as honeycomb masses is more common. Smithsonite is harder thanmost carbonate minerals; it cannot be scratched by a penny, but it can bescratched by a knife. It fizzes in cold hydrochloric acid.SODIUM COMPOUNDS - Natural soda ash, and trona used in many industriesas sodium carbonates are produced in California and Wyoming.SPHALERITE - Sphalerite, also called zine blende, black jack and mock lead,is composed of zinc sulfide (ZnS), and is the most important ore of zinc.Sphalerite when Pure is nearly colorless, but it is commonly brown, yellow,black, or dark red because of impurities. It has a white to dark brown streakwhich is always much lighter than the color of the specimen. As a rule, themineral crystals are shaped like triangular pyramids, with three sides and a base:because it has good cleavage in six directions sphalerite will break intotwelve-sided blocks. It has a brilliant, resinous, or almost metallic luster, and isharder than a penny but can be scratched with a knife. Some sphalerite is foundas massive deposits varying from coarse to fine-grained. In hydrochloric acidit dissolves and forms hydrogen sulfide which has an unpleasant odor. Sphaleriteis easily identified by its cleavage and resinous luster.STONE - Concreted earthy or mineral matter. A small piece of rock. Rock orrock-like material for building. Large natural masses of stone are generallycalled rocks: small or quarried masses are called stones: and the finer kinds,gravel or sand.STONE-SAND - Refers to the product (usually less than 1⁄4-inch in dia.)produced by the crushing of rock. This material is usually highly processed, andshould not be confused with screenings.SUB GRADE - The upper surface of the native foundation on which is placedthe road material or artificial foundation, in case the latter is provided.


214SUB-SOIL - 1. Broadly and loosely, the part of the regolith (earth mantle)which lies beneath the true soil and which contains almost no organic matter.2. More precisely, a layer of the regolith, grading into the soil above and intounmodified rock waste below, which is less oxidized and hydrated than the soilproper and contains almost no organic matter, but is somewhat charged with andindurated by iron oxides and clay that has been leached down from the overlyingsoil.SYENITE - Any granular igneous rock composed essentially of orthoclase,with or without microcline, albite, hornblende, biotite, augite, or corundum. (La Forge) . In mica syenites hornblende is replaced by biotite and in augitesyenites it is replaced by augite. If a small quantity of quartz is present it is calledquartz syenite. In nepheline syenite the feldspar is partly replaced by nepheline.(U. S. Geol. Surv.)TAILINGS - Stones which after going through the crusher, do not pass throughthe largest openings of the screen.TALC (Mineral) - A soft mineral of a soapy feel, in composition an acidmagnesium metasilicate, H2Mg3(SiO3)4. New York, California and NorthCarolina account for 64% of the output.TOPSOIL - (Road Surface) A variety of surfacing used principally in thesoutheastern states, being the stripping of certain topsoils which contain anatural sand-clay mixture. When Placed on a road surface, wetted and puddledunder traffic it develops considerable stability.TRACHYTE - Any aphanitic, aphanophyric, or glassy igneous rocks composedessentially of alkali feldspar, with or without mica, amphibole, pyroxene, andother accessories, or of rock glass having essentially the same composition . (LaForge) It was formerly used for both rhyolite and trachyte proper, as a field termfor light-colored lavas and porphyries. Compare Acmite-trachities andPantellerites. (Kemp)TRAP - Includes the dark-colored, fine-grained and dense igneous rockscomposed of the ferromagnesian minerals, basic feldspars, and little or noquartz. The ordinary commercial variety of trap is basalt, diabase, or gabbro.TUFF - A sedimentary rock composed of fine material - volcanic dust, so-calledash and cinders, and lapilli - explosively ejected from a volcano. Tuff may ormay not be deposited in water- it may be either heterogeneous or rather wellsorted, and it may be either incoherent or indurated. (La Forge)URANIUM (Chemical) - A radioactive element of the chromium group, foundin combination in pitchblende and certain other rare minerals, and reduced asa heavy, hard, nickel-white metal .VOLCANIC ASH - Volcanic ash or volcanic dust (in some places called“silica” although this name is not exactly accurate) consists of tiny glass orcongealed lava fragments which have been blown into the atmosphere duringthe eruptions of volcanoes. It is a type of extrusive rock, that has been forcedout or extruded onto the earth’s surface. Under a microscope or a hand lens, ashis seen to contain small curved pieces of glass which are the broken walls ofbubbles of the lava rock which burst from the volcano. Ash can easily bedistinguished from other rocks, principally sand, by its white to bluish graycolor. Its glassy surfaces sparkle in the sun, and its particles do not dissolve inacid as do particles of limestone and chalk. It is used for many purposes: intoothpastes and powders, as abrasives, cleaning compounds, glazes for potteryin filters, and in the manufacture of cement and road asphalt.
