SCREW CONVEYORS
The history of the screw conveyor-one of man’s simplest
and most efficient tools for the conveying of bulk materials -
can be traced back more than 2,000 years to ancient Greece
and the development of the "Archimedean Screw."
About 240 b.c., Archimedes, a renowned Greek math-
ematician and inventor, perfected a spiraled tubular de-
vice for removing water from the hold of a large ship. In
doing so, he became the first man to put the screw con-
veyor principle into practical application.
Today the screw conveyor plays an important role in a
wide variety of industries. Because it is compact, versatile
and economical, it has become one of the most useful
mechanisms for the transport and distribution of bulk ma-
terials.
Aside from its utility as a means of moving materials,
the screw conveyor, with certain modifications and/or varia-
tions in mechanical arrangement, may also be used to
perform, a number of other important functions.
It can be used to mix, blend or agitate. In applications
where close control of material flow is critical, the screw
conveyor may be used as a highly accurate metering de-
vice. Operating in a jacketed housing it may be used as a
heating or cooling device. Because it can be effectively
sealed, it is extremely valuable in applications where dust
or fumes must be confined inside the conveyor or where
moisture or contaminants must be kept out.

A study has been made to define the characteristics of bulk materials in terms which are readily recognized. These characteristics and termsare indicated in the Material Classification Code Chart (Table 1-1). It can be seen that different materials having the same classification code
number may be handled with screw conveyors having the same specifications. Also, should it be desired to handle a material not given in theMaterial Table, in some cases it is possible to make at least a preliminary selection of material code number by comparing the material with
similar listed materials.
It should be borne in mind that because of the peculiar action of a conveyor screw in moving bulk materials, the condition of the material in
transit may be quite dif ferent from the condition at rest.
Materials, first of all, are classified according to particle size. It is important to have a screen analysis made of the material, if at all possible.
For example if a material is said to consist of ½ inch and under, it may be similar to granules of plastic. Or it may have only 10% of ½” particle size,with 90% fines grading to micron sizes. Some materials may require use of cover gaskets and/or seals; others may not, depending upon material
characteristics.
Lumpy materials must be checked against the Lump Size Table (Table 1-7). Very often larger screw conveyors must be used solely to
accommodate the lumps than otherwise would be required from a standpoint of normal capacity.
Irregular, stringy, and interlocking materials that mat or cling together require special consideration. Stringy materials, particularly if longenough, may wrap around the pipe shaft of the conveyor screw or around the intermediate hanger bearings, thus effectively clogging the
conveyor. Materials that mat may also be those that pack under pressure. If the material does pack under pressure, it may jam the conveyor
screw and seriously damage the conveyor. All materials with these characteristics must be carefully studied in detail with respect to their actionsin a screw conveyor.
Materials are also classified as to their flowability. This, unfortunately, is a relative term and not easily measured. However, so far as the
operation of screw conveyors is concerned, flowability is related to two factors, one the angle of slide and the other the internal friction of the
material. The angle of slide may be determined by tilting a plate carrying a quantity of the material. The angle of internal friction may be evaluatedfrom shear cell test data. Changes in moisture content, temperature, particle size distribution and chemically corrosive action of the material all
affect the flowability.
Experience with screw conveyors shows that the more free flowing the material is, the less horsepower will be required to transport it. The
converse also is true. Because flowability isn’t easily reduced to numerical terms, in some instances actual experience has been the guide incodifying the flowability of the materials in Table 1-1.
Judging a material just from its angle of repose is misleading. Some materials which have a very high angle of repose when stored in a bin
may have a very low angle of repose in the “as conveyed” condition in a screw conveyor. An example of this is wheat bran. Its particles vary widely
in shape and size, yet it appears to have a relatively low angle of “repose,” or rather angle of slide, while moving through a screw conveyor.
It is known that some materials which are uniform in particle shape and size are quite free flowing when dry. Screened dry sand is freeflowing. The addition of moisture, however, changes the flowability character. Likewise, dry granulated sugar is free flowing, but this material is
hygroscopic and will pick up moisture from the air . If this happens, its flowability is changed considerably. The flowability of most materials is
affected by changes in their moisture content, with consequent changes in their ability to be conveyed.
The abrasiveness of materials is also a relative quantity and isn’t easily defined with accuracy. Some materials are more abrasive thanothers. It will be found that nonabrasive or very mildly abrasive materials may be handled with screw conveyors with standard gauge screws and
troughs as specified in the Component Group 1A for Normal Service, Table 1-8. Very abrasive materials require heavier than standard
components. See Component Groups in Tables 1-9 and 1-10. Most abrasive materials in the following Material Table, Table 1-1, are handled atlower cross-sectional loads than are the nonabrasive materials. This is done to attain the maximum economical life of the conveyor and its
parts.
The selection of components for handling abrasive materials should also be considered in view of the amount of service to which the
conveyor will be subject. Continuous, 24-hour-per-day operation will cause more wear than if the conveyor were operating but a few hours perday.
All of the foregoing bulk material characteristics are described in more detail in CEMA Standard No. 550 entitled Classification and Defini-
tions of Bulk Materials. Chapter II of that publication fully explains size classification and coding, flowability coding and abrasive coding. In
addition there are certain other miscellaneous bulk material characteristics that are defined in as hazards affecting conveyability. The effect ofsome of these hazards as they affect screw conveyor design follows.

K. Some bulk substances are sensitive to small changes in temperature or pressure. For example, materials containing vegetable oils orfats can become spoiled by the heat of friction in a hanger bearing.
L. Dusty materials—especially those that are very dusty—should be carefully considered. Previous experience with similar materials is the
best guide. Flange gaskets and special trough end seals may be needed. See Page 33 for several classes of enclosures.
M. Some materials such as dry Portland cement will aerate and develop fluid characteristics as a result of transport in a screw conveyor. The
“as conveyed” apparent density is much lower than the normal apparent density. Many dusty and aerated materials can bypass anintermediate discharge spout. As the material becomes more fluid-like, the flowability increases markedly, and in some cases the aerated
material will flood and run like water with the result that the cross-sectional load increases and control of the rate of flow is lost. Consult
your conveyor manufacturer regarding materials which may aerate greatly.
N. Dusts associated with certain bulk materials are flammable or even explosive when mixed with air in the proper concentration. It thereforemay be necessary to contain dust laden material at all times within the conveyor enclosure. Grain dust is an example. The very nature of
a screw conveyor—being an enclosed conveying device—may be used for handling materials with flammable or explosive dusts, al
though more sophisticated than standard enclosures may be required. Consult Page 33, Classes of Enclosures.
P&Q. Contaminable and degradable materials must be recognized because their salability or use may be affected by improper conveying or ill-considered conveyor specifications. Suitable non-lubricated bearings should be used. Low conveyor speeds normally will prevent exces-
sive degradation.
R. Materials in this category are similar to those described under L and N, except that exposure of the dust or fumes may be hazardous to
personnel. Tight enclosures and spouting connections—usually gasketed—are required. Elaboration of the enclosures depends uponthe severity of the hazard.
S&T. Corrosion protection requiring the use of special metals is a common problem. Here again “corrosion” is a relative term which isn’t easilydefined numerically. The choices of materials of construction, such as the types of stainless steel or other special metals, should be
referred to the conveyor manufacturer.
U. Certain bulk materials are hygroscopic. They absorb water from the moisture in the ambient atmosphere. The water they pick up changes
their flowability, of course, and this has been taken into account for the usual behavior of such materials as listed in Table 1-1.
V&X. Bulk materials which interlock and mat usually will require screws of heavier than standard construction and flight edges that can cut theirway through the material. Intermediate hanger bearings may have to be eliminated. A similar condition exists for materials which pack
under pressure.
W. Oils or chemicals that may be contained in bulk materials require special consideration. Some of these constituents may make the
materials sticky and cause adherence to the working parts of the conveyor. Ribbon type conveyor screws sometimes help. It is best toconsult your conveyor manufacturer when attempting to handle such materials.
Y. Light and fluffy materials require consideration similar to those which are dusty or which tend to aerate as they are conveyed. Seeparagraphs L and M.
Z. Elevated temperatures are encountered in many phases of material processing. Screw conveyors should be fabricated of heavier than
standard construction and designed to withstand the inevitable expansion and contraction that takes place. Intermediate hanger bearings
must be protected against heat or omitted. End bearings and drive equipment may be separated from the trough end to reduce theirexposure to heat. Consult Expansion of Screw Conveyors Handling Hot Materials.

PREFACE TO MATERIAL TABLE 1-2
The Material Table 1-2 lists a wide range of bulk materials that can be handled in screw conveyors. The table shows in the first column therange of density that is usually experienced in handling that material. The average density is not specifically shown but is of ten assumed to be at
or near the minimum.
The next column shows the material code number. This consists of the average density, the usual size designation, the flowability number,
the abrasive number followed by those material characteristics which are termed conveyability hazards.
The component series column refers to selection of conveyor components as used in Tables 1-8, 1-9 and 1-10.
A very fine 100 mesh material with an average density of 50 lbs. per cubic foot, that has average flowability and is moderately abrasive, would
have a material code 5OA100
36. If this material were very dusty and mildly corrosive the number would then be 5OA100
36LT.
The Material Factor is used in the horsepower formula to determine the horsepower to operate a horizontal screw conveyor. The calculation
of horsepower is shown on page 27.
The information and data in the Material Table, Table 1-2, has been compiled by members of CEMA and represents many years of experiencein the successful design and application of screw conveyors for handling the listed materials. The indicated physical characteristics of these
materials are not the result of any particular laboratory tests but were learned from the actual industrial operation of countless screw conveyors.
The Material Table includes various grains, seeds, feeds, etc. that are commonly handled in many conveyor types. The published unit
weights, the component series and material factors Fm are for average conditions. For instance, wheat when dry or with a low moisture of lessthan 10% is very free flowing, and the Fm factor of .4 can be used. When higher moistures are prevalent, a material factor of .5 or .6 is suggested.
This phenomena is common to all grains and some other substances.
It should also be noted that soybeans are shown as being very abrasive. Heavy conveyor construction is recommended. This is because
soybeans, especially when dirty and harvested at a low moisture, are extremely abrasive. On the other hand, hard iron bearings which arecommonly used with abrasive materials cannot be recommended because of spark generation and consequent dust explosions. This phenom-
ena is also true of rough rice and to a lesser degree on other grains.
THE MATERIAL TABLE IS A GUIDE ONLY. THE MATERIALS CODE AND THE MATERIAL FACTOR Fm ARE BASED ON EXPERIENCE OF
SEVERAL CONVEYOR MANUFACTURERS. A SPECIFIC MATERIAL SAMPLE MAY HAVE PROPERTIES THAT VARY FROM THOSE SHOWNIN THE TABLE. THE RANGE OF DENSITIES WILL ALSO VARY DEPENDING ON MOISTURE CONTENT AS WELL AS ITS SOURCE.

In order to determine the size and speed of a screw conveyor, it is necessary first to establish the material code number. It will be seen fromwhat follows that this code number controls the cross-sectional loading that should be used. The various cross-sectional loadings shown in the
Capacity Table (Table 1-6) are for use with the standard screw conveyor components indicated in the Component Group Selection Guide onpage 25 and are for use where the conveying operation is controlled with volumetric feeders and where the material is uniformly fed into the
conveyor housing and discharged from it. Check lump size limitations before choosing conveyor diameter. See Table 1-7.
Capacity Table
The capacity table, (Table 1-6), gives the capacities in cubic feet per hour at one revolution per minute for various size screw conveyors forfour cross-sectional loadings. Also shown are capacities in cubic feet per hour at the maximum recommended revolutions per minute.
The capacity values given in the table will be found satisfactory for most all applications. Where the capacity of a screw conveyor is very
critical, especially when handling a material not listed in Table 1-2, it is best to consult our Engineering Department.The maximum capacity of any size screw conveyor for a wide range of materials, and various conditions of loading, may be obtained from
Table 1-6 by noting the values of cubic feet per hour at maximum recommended speed.
Conveyor Speed
For screw conveyors with screws having standard pitch helical flights the conveyor speed may be calculated by the formula:
For the calculation of conveyor speeds where special types of screws are used, such as short pitch screws, cut flights, cut and folded flightsand ribbon flights, an equivalent required capacity must be used, based on factors in the Tables 1-3, 4, 5.
Factor CF1 relates to the pitch of the screw. Factor CF2 relates to the type of the flight. Factor CF3 relates to the use of mixing paddles within
the flight pitches.The equivalent capacity then is found by multiplying the required capacity by the capacity factors. See Tables 1-3, 4, 5 for capacity factors.

SCREW CONVEYORS

To facilitate the selection of proper specifications for a screw conveyor for a particular duty, screw conveyors are broken down into threeComponent Groups. These groups relate both to the Material Classification Code and also to screw size, pipe size, type of bearings and trough
thickness. Referring to table 1-2, find the component series designation of the material to be conveyed. Having made the Component Seriesselection, refer to Tables 1-8, 9, 10 which give the specifications of the various sizes of conveyor screws. (The tabulated screw numbers in this
table refer to standard specifications for screws found on pages 61-69, Component Section). These standards give complete data on the
screws such as the length of standard sections, minimum edge thickness of screw flight, bushing data, bolt size, bolt spacing, etc.
EXAMPLE: For a screw conveyor to handle brewers grain, spent wet, refer to the material characteristics Table 1-2. Note that the componentseries column refers to series 2. Refer now to page 25, component selection, Table 1-9, component group 2. The standard shaft
sizes, screw flight designations, trough gauges and cover gauges are listed for each screw diameter.
LUMP SIZE LIMITATIONS COMPONENT GROUP
The size of a screw conveyor not only depends on the capacity required, but also on the size and proportion of lumps in the material to behandled. The size of a lump is the maximum dimension it has. If a lump has one dimension much longer than its transverse cross-section, the
long dimension or length would determine the lump size.The character of the lump also is involved. Some materials have hard lumps that won’t break up in transit through a screw conveyor. In that
case, provision must be made to handle these lumps. Other materials may have lumps that are fairly hard, but degradable in transit through the
screw conveyor, thus reducing the lump size to be handled. Still other materials have lumps that are easily broken in a screw conveyor and lumpsof these materials impose no limitations.
Three classes of lump sizes are shown in TABLE 1-7 and as follows
Class 1
A mixture of lumps and fines in which not more than 10% are lumps ranging from maximum size to one half of the maximum; and 90% arelumps smaller than one half of the maximum size.
Class 2A mixture of lumps and fines in which not more than 25% are lumps ranging from the maximum size to one half of the maximum; and 75% are
lumps smaller than one half of the maximum size.
Class 3A mixture of lumps only in which 95% or more are lumps ranging from maximum size to one half of the maximum size; and 5% or less are
lumps less than one tenth of the maximum size.
LUMP SIZE LIMITATIONS
*For special pipe sizes, consult factory.
**Radial clearance is the distance between the bottom of the trough and the bottom of the conveyor pipe.EXAMPLE: Lump Size Limitations
To illustrate the selection of a conveyor size from the maximum lump size table, table 1-7, consider crushed ice as the conveyed material.
Refer to the material charts table 1-2 and find crushed ice and its material code D3-35-Q and weight of 35-45 lbs./C.F. D3 means that the lumpsize is 1½” to 3”, this is noted by referring to the material classification code chart on page 14. From actual s p e c i fications regarding crushed
ice it is known that crushed ice has a maximum lump size of 1½” and only 25% of the lumps are 1½” . With this information refer to table 1-7,Maximum lump size table. Under the column Class II and 1½” Max. lump size read across to the minimum screw diameter which will be 9”.

HORSEPOWER REQUIREMENTS
Horizontal Screw Conveyors*Consult Factory for Inclined Conveyors or Screw Feeders
The horsepower required to operate a horizontal screw conveyor is based on proper installation, uniform and regular feed rate to theconveyor and other design criteria as determined in this book.
The horsepower requirement is the total of the horsepower to overcome friction (HPf) and the horsepower to transport the material at thespecified rate (HPm) multiplied by the overload factor Fo and divided by the total drive ef ficiency e, or:
HP f =
HPm =
Total HP =
The following factors determine the horsepower requirement of a screw conveyor operating under the foregoing conditions.
L = Total length of conveyor, feet
N = Operating speed, RPM (revolutions per minute)Fd = Conveyor diameter factor (See Table 1-12)
Fb = Hanger bearing factor (See Table 1-13)

HORSEPOWER
PROBLEM: Convey 1,000 cubic feet per hour Brewers grain, spent wet, in a 25´-0” long conveyor driven by a screw conveyor drive with V-belts.
SOLUTION:1.Refer to material characteristic table 1-2 for Brewers grain, spent wet and find:
A.wt/cf: 55 - 60
B.material code: C½ - 45TRefer to table 1-1, material classification code chart where:
C½ = Fine ½” and under4 = Sluggish
5 = Mildly abrasive
T = Mildly corrosiveC.Intermediate bearing selection: L or S
Refer to table 1-11 Bearing Selection, Find:L = Bronze
S = Nylatron, Nylon, Teflon, Hi-density, Polyethylene, Graphite Bronze, Oil-impreg. Bronze, and oil-impreg. wood.
D.Material Factor: Fm = .8E.Trough Loading: 30%A
Refer to Table 1-6 capacity table and find 30%A which shows the various capacities per RPM of the standard size screw conveyors and themaximum RPM’s for those sizes.
2.From Table 1-6, Capacity table under 30%A note that a 12” screw will convey 1,160 cubic feet per hour at 90 RPM maximum, therefore at 1RPM a 12” screw will convey 12.9 cubic feet. For 1,000 CFH capacity at 12.9 CFH per RPM, the conveyor must therefore run 78RPM (1000 ÷
12.9 = 77.52).
3.With the above information and factors from Tables 1-12 through 1-17 refer to the horsepower formulas on page 27 and calculate the
required horsepower to convey 1000 CF/H for 25 feet in a 12” conveyor.
Using the known factors find that:
L = 25´ C = 1000 CFH
N = 78 RPM from step 2 above W = 60#/CF from step 1AFd = 55 see Table 1-12, for 12” Ff = 1 see Table 1-14, standard 30%
Fb = 2.0 see Table 1-13 for L Fp = 1 see Table 1-15e = .88 see Table 1-17
4. Solve the following horsepower equations:
A. HP f =
B. HPm =
Find the Fo factor from 1-16; by adding HPf and HPm and matching this sum to the values on the chart.
C. HPf =
SOLUTION:3.05 Horsepower is required to convey 1,000 CFH Brewers grain, spent wet in a 12” conveyor for 25 feet. A 5 H.P. motor should be used.

TORSIONAL RATINGS OF CONVEYOR SCREW PARTS
Screw conveyors are limited in overall design by the amount of torque that can be safely transmitted through the pipes, couplings, andcoupling bolts.
The table below combines the various torsional ratings of bolts, couplings and pipes so that it is easy to compare the torsional ratings of allthe stressed parts of standard conveyor screws.
** Values shown are for A307-64, Grade 2 Bolts. Values for Grade 5 Bolts are above x2.5*Values are for unheattreated shafts.
The lowest torsional rating figure for any given component will be the one that governs how much torque may be safely transmitted. For
example, using standard unhardened two bolt coupling shaf ts, the limiting torsional strength of each part is indicated by the underlined figures inTable 1-18.
Thus it can be seen that the shaft itself is the limiting factor on 1”, 1½” and 2” couplings. The bolts in shear are the limiting factors on the2v” coupling and on the 3” coupling used in conjunction with 4” pipe. The bolts in bearing are the limiting factors for the 3” coupling used in
conjunction with 3½” pipe, and for the 3v” coupling.
Formula: Horsepower To Torque (In. Lbs.)
EXAMPLE: 12” Screw, 78 RPM, 5 Horsepower
From the table above 2” shafts with 2 bolt drilling and 2½” std. pipe are adequate (4,040 < 7600).
If the torque is greater than the values in the above table, such as in 2” couplings (torque > 7600), then hardened shafts can be used as
long as the torque is less than the value for hardened couplings (torque < 9500). If the torque is greater than the 2 bolt in shear value but lessthan the 3 bolt in shear value then 3 bolt coupling can be used. The same applies with bolts in bearing. When the transmitted torque is greater
than the pipe size value, then larger pipe or heavier wall pipe may be used. Other solutions include: high torque bolts to increase bolt in shear
rating, external collars, or bolt pads welded to pipe to increase bolt in bearing transmission. For solutions other than those outlined in the abovetable please consult our Engineering Department.

CONVEYOR SCREW DEFLECTION
When using conveyor screws of standard length, deflection is seldom a problem. However, if longer than standard sections of screw areto be used, without intermediate hanger bearings, care should be taken to prevent the screw flights from contacting the trough because of
excessive deflection. The deflection at mid span may be calculated from the following formula.
Where:D = Deflection at mid span in inches
W = Total screw weight in pounds, see pages 82-86
L = Screw length in inchesl = Movement of intertia of pipe or shaft, see table 1-20 or 1-21

EXAMPLE: Determine the deflection of a 12H512 screw conveyor section mounted on 3” sch 40 pipe, overall length is 16’-0”.
W = 272#
L = 192”I = 3.02 (From chart above)
Applications where the calculated deflection of the screw exceeds .25 inches (¼”) should be referred to our Engineering Department for recom-mendations. Very of ten the problem of deflection can be solved by using a conveyor screw section with a larger diameter pipe or a heavier wall
pipe. Usually, larger pipe sizes tend to reduce deflection more effectively than heavier wall pipe.

Classes of EnclosuresConveyors can be designed to protect the material being handled from a hazardous surrounding or to protect the surroundings from a
hazardous material being conveyed.This section establishes recommended classes of construction for conveyor enclosures — without regard to their end use or application.
These several classes call for specific things to be done to a standard conveyor housing to provide several degrees of enclosure protection.
Enclosure ClassificationsClass IE — Class IE enclosures are those provided primarily for the protection of operating personnel or equipment, or where the enclosure
forms an integral or functional part of the conveyor or structure. They are generally used where dust control is not a factor or whereprotection for, or against, the material being handled is not necessary — although as conveyor enclosures a certain amount or
protection is afforded.
Class IIE — Class IIE enclosures employ constructions which provide some measure of protection against dust or for, or against, the materialbeing handled.
Class IIIE — Class IIIE enclosures employ constructions which provide a higher degree of protection in these classes against dust, and for oragainst the material being handled.
Class IVE — Class IVE enclosures are for outdoor applications and under normal circumstances provide for the exclusion of water from the
inside of the casing. They are not to be construed as being water-tight, as this may not always be the case. When more than onemethod of fabrication is shown, either is acceptable.

Left and Right Hand ScrewsA conveyor screw is either right hand or left hand depending on the form of the helix. The hand of the screw is easily determined by looking
at the end of the screw.
The screw pictured to the left has the flight helix wrapped around the pipe in a counter-clockwise direction, or to your left. Same as left handthreads on a bolt. This is arbitrarily termed a LEFT hand screw.
The screw pictured to the right has the flight helix wrapped around the pipe in a clockwise direction, or to your right. Same as right hand
threads on a bolt. This is termed a RIGHT hand screw.A conveyor screw viewed from either end will show the same configuration. If the end of the conveyor screw is not readily visible, then by
merely imagining that the flighting has been cut, with the cut end exposed, the hand of the screw may be easily determined.

CONVEYOR HOUSING
The most commonly employed U-trough is the angle-flanged type. The
top flange is fabricated with heavy-duty structural steel angles weldedflush with the top housing edge. End flanges are jig-welded to insure
proper alignment with other trough sections.
The top flange is formed from the same sheet as the trough, resulting in
a lightweight, yet rigid, housing section. End flanges are jig-welded forperfect alignment with other sections.
The channel U-trough is well suited for applications requiring long dis-tances between conveyor supports. Upper trough sides are fabricated
with structural steel channels to which the lower contoured section may
be bolted or spring clamped.Useful for abrasive applications where frequent replacement of the low-
er formed section is anticipated.
Intended for applications where quick, convenient access to the con-veyor interior is required, the drop bottom trough consists of rigid upper
side channels to which a lower contoured section is attached. One sideof the lower formed section is hinged while the other is attached by use
of spring clamps or other type of quick-opening device.
The jacketed housing consists of a U-trough and continuously weldedsteel jacket which forms a chamber between the inner and outer walls
for heating or cooling media. Built to specifications to suit individual
requirements. May be fabricated to A.S.M.E. code specifications.
All WAM, Inc. conveyor housings are available in stainless steel. All housings may also be furnished hot-dipped galvanized. For specific alloy
materials available, consult the Engineering Department.

CONVEYOR HOUSING
Intended primarily for sticky or slightly viscous materials, the flared troughis most often employed with ribbon conveyors. Top flanges are formed
from the same sheet as the housing. End flanges are jigwelded for per-
fect alignment with other sections.
Tubular housings are inherently dust and weathertight, rigid and may
be readily loaded to a full cross section. The standard tubular housing is
rolled from a single sheet and continuously welded at the seam.
Angle flanged tubular housings consist of semicircular formed halves,each of which includes an angle flange of structural steel. The two sec-
tions are bolted together to form the tubular housing.
This type is similar to the angle flanged except that the flanges are formed
from the same sheet as that of the contoured half sections, thus result-
ing in a rigid, lightweight tubular section. The halves are bolted togetherto form the complete housing.
Rectangular housings are well suited for highly abrasive applications.
The material is allowed to form on the trough bottom, thus preventing
abrasion directly against the housing wall. Top flanges are fabricated ofstructural steel angle welded flush with the top housing edge.
The top flange for this type housing is formed from the same sheet asthe trough, thus providing a rigid, yet lighter, housing.�

DISCHARGES
FLUSH END DISCHARGE SPOUTThis spout is designed for use at the final discharge point. The end of
the spout is comprised of a hous ing end with bottom flange drilled withstandard discharge flange bolt pattern. Because it is located at the
extreme end of the conveyor, there is no carryover of material past the
final discharge point. The flush end arrangement eliminates the unnec-essary extension of trough and interior components beyond the actual
discharge point.
STANDARD DISCHARGE SPOUTThe rack and pinion discharge gate with flat slide is designed for use
with standard spouts. It bolts directly to the spout flanges. The flat slide
is actuated by one or more pinions which mesh with racks bolted to theslide bottom. The gate may be operated by hand, chain or rope wheel.
This unit is also available with pneumatic actuator.
STANDARD SPOUT WITH HAND SLIDE
Standard spouts are fabricated in various gauges proportionate to the
thickness of the conveyor housing.They are generally furnished welded to the housing but may also be
furnished loose for attachment in the field. Bottom flanges of the spoutare drilled with standard discharge bolt pattern for interchangeability and
convenient assembly.
RACK & PINION GATE WITH FLAT SLIDEThe rack and pinion gate with curved slide is similar to the flat-slide unit
except that the slide is contoured to match the conveyor housing. Thecurved slide eliminates the “pocket” formed in the flat slide discharge
assembly. This unit is also available with hand, chain or rope wheel. It
may also be furnished with pneumatic actuator.
RACK & PINION GATE WITH CURVED SLIDE
This spout also may be furnished with hand slide gate.
The slide gate assembly is bolted directly to the discharge flanges. Theslide may be positioned for opening from either side or for opening par-
allel to the conveyor.
DUST-TIGHT RACK & PINION GATE
Available with either flat or curved slide, the dusttight rack and piniongate is furnished completely enclosed.
This unit may be operated by hand, chain or rope wheel or may be
furnished with pneumatic actuator.

HOUSING ENDS
All WAM, Inc. conveyor housing ends are manufactured to close tolerances from quality, heavy-gauge steel. Assembly bolt holes are jig-drilled for perfect alignment with housing end flanges.
Ball bearings are standard with housing ends, but roller bearings or friction type bearings may be furnished. Ends may also be furnished
without bearings. All WAM, Inc. conveyor housing ends are available in stainless steel. For other alloys available, consult WAM, Inc’s Engineering Department.
Standard ends are furnished in six basic types, most of which are available for U- or flared trough and tubular and rectangular housings.Inside trough ends are available for U-trough only.
Discharge ends are available for all but tubular housings, and flush discharge ends are available for all but flared trough. All, except the inside
trough end, are designed for outside assembly.
U-Trough Flared Tubular Rectangular
U-Trough Flared Tubular Rectangular
STANDARD HOUSING ENDS
Standard housing ends are the most commonly used. Support is provided by means of a separate flange foot or saddle. This end type provides
for convenient assembly and disassembly.
Ends with feetare identical to the above type, except they are manufactured with an integral bottom flange foot.
Outboard bearing ends may be used either for double bearing arrangements or for mounting one bearing and, a seal. An integral pedestal
supports the pillow-block bearing.
Flush discharge ends are designed for use with Industrial flush-end discharges. Bottom flange is drilled with standard discharge flange pattern.
Discharge ends are designed to allow discharge directly from the housing end.
Inside trough ends are designed for inside assembly. Separate support is required and the standard trough flange must be omitted.

SEALS
The packed gland seal is a highly effective means of sealing the con-
veyor both internally and externally. This seal also is suitable for pres-sure or vacuum service. Mechanical compression of the packing mate-
rial is accomplished by means of four compression bolts. Available inbolt-on. Designed for use with outboard bearing ends.
This universal type seal is designed for use with waste packing or car-
tridge-type lip or felt seals. An opening at the top of the housing facili-
tates waste repacking. The packing material is partially exposed for oil-ing. The packing seal housing is mounted outside between the end bear-
ing and the conveyor end. It may also be mounted independently foruse with the outboard bearing end.
This unit, designed for interior mounting, provides an effective seal by
compression of the packing which is contained in a split housing to fa-
cilitate assembly and replacement of the packing material. Packing pres-sure may be adjusted by means of two exposed nuts at the top half of
the seal housing.
The plate seal is an economical, effective sealing device designed for
exterior mounting between the end bearing and the conveyor housingend. Standard unit s include lip-type seals, but other types of commer-
cial seal cartridges may also be used. The plate seal and the end bear-
ing are attached by means of common bolts. The plate may also beattached independently when outboard bearing ends are used.

THRUST BEARING
An operating screw conveyor creates an inherent thrust load opposite the direction of material flow. This thrust load-if not transmitted to the
appropriate stationary components-can result in severe damage to hanger bearings. Therefore, one end bearing should always be of a designthat will prohibit thrust-induced axial movement of the conveyor screw. To prevent possible deflection of the screw, the thrust bearing unit,
whenever possible, should be located so that the screw is held in tension rather than in compression. When located at the discharge end, the
thrust bearing holds the screw in tension. At the intake end, the bearing maintains the screw in compression.
Several types of thrust bearings are available for varying degrees of thrust:
Type E end thrust bearings, designed for medium thrust and radialloads, are efficient, economical and the most widely used of all end
thrust types. Although thrust loading capacity is bi-directional, the unit
should always be used at the discharge end to keep the screw in ten-sion. Dual roller bearings are housed in precision-machined gray iron
housings. The shaf t is retained to the bearing inner race by means ofexterior spring steel snaprings. The bearing housing includes lip- type
seals for protection of bearings. A plate- type assembly is provided to
prevent material loss or, inverted, to prevent contamination of material.

CONVEYOR SCREWS
HELICOIDSTANDARD WAM, Inc. helicoid conveyor screws are cold -rolled
from special-analysis strip steels on unique rolling mills designed and
built by WAM, Inc.Although the rolling operation compresses the outer flight edge, or
periphery, to approximately 50% of the inside root, the cold-rolling pro-cess produces a smooth, work-hardened surface which actually has in-
creased wear resistance.
Dimensional tolerances of all WAM, Inc. conveyor screws conformto industry standards established by the Conveyor Equipment Manu-
facturers Association.To produce the completed conveyor section, the continuous, one-
piece helix is mounted on the conveyor pipe with heavy-duty end lugs
and regularly spaced intermediate welds. For special applications, theflighting may be continuously welded to the pipe on one or both sides.
Pipe ends are bushed with close-tolerance internal collars whichare pressure-inserted and plug-welded for maximum efficiency and ser-
vice life. The collars are accurately reamed for the proper coupling shaft
diameter. Coupling bolt holes are jig -drilled for perfect alignment.Helicoid conveyors may be furnished in various materials, and some
specific sizes are available in stainless steel (see dimensional table,page 82).
Helicoid screws may also be furnished with hard-surfaced flights.
Standard helicoid conveyors are interchangeable with standard sec-tional-flight conveyors (see comparison table, opposite page).
Numerous deviations from standard are available for virtually anyapplication. For description of basic flight types, including common flight
modifications and pitch deviations, refer to page 62.
SECTIONALWAM, Inc. sectional-flight conveyor screws consist of individual flight
segments which are cold -formed from separate flat-plate blanks andthen butt-welded to form the helix.
The flights are anchored securely at each end of the conveyor pipe
by formed steel lugs and with carefully spaced intermediate welds. Forsevere conveying applications, the flights may be continuously welded
to the conveyor pipe on one or both sides.Sectional flights, unlike helicoid flighting, have uniform thickness at
the outer edge and inside root. Sectional conveyors are available in a
wider range of sizes, materials, weights and thicknesses.All WAM, Inc. sectional conveyor screws are available in stainless
steel. They may also be furnished in abrasion-resistant steel or may behard-surfaced for longer service life.
Virtually any combination of flight thickness, diameter, pitch and ma-
terials can be furnished to suit almost any conveying application.As with helicoid, flight ends are bushed with standard WAM, Inc.
internal collars. The collars are pressure -fitted and plug welded andreamed for the appropriate coupling diameter.
Coupling bolt holes are also jig -drilled for perfect alignment of pow-
er-transmitting components.Sectional-flight conveyor screws are fully interchangeable with stan-
dard helicoid conveyors (see comparison table, pages 110-111). Nu-merous deviations from standard may be employed for special applica-
tions.
For description of basic flight types, including the most commonflight modifications and pitch deviations, refer to page 62.

Conveyor screws with pitchequal to screw diameter are
considered standard. They
are suitable for a wide rangeof materials in most conven-
tional applications.
CONVEYOR SCREWS
BASIC CONVEYOR FLIGHT AND PITCH TYPES
STANDARD PITCH, SINGLE FLIGHT TAPERED, STANDARD PITCH, SINGLE FLIGHT
Screw flights increase from 2/3to full diameter. Used in screw
feeders to provide uniform with-drawal of lumpy materials. Gen-
erally equivalent to and more
economical than variable pitch.
Flight pitch is reduced to 2/3 di-ameter. Recommended for in-
clined or vertical applications.
Used in screw feeders. Shorterpitch retards flushing of materi-
als which fluidize.
SHORT PITCH, SINGLE FLIGHT SINGLE CUT-FLIGHT, STANDARD PITCH
Screws are notched at regularintervals at outer edge. Affords
mixing action and agitation of
material in transit. Useful formoving materials which tend to
pack.
HALF PITCH, SINGLE FLIGHT
Similar to short pitch, except
pitch is reduced to 1/2 standardpitch. Useful for vertical or in-
clined applications, for screw
feeders and for handling ex-tremely fluid materials.
CUT & FOLDED FLIGHT, STANDARD PITCH
Folded flight segments lift andspill the material. Partially re-
tarded low provides thorough
mixing action. Excellent forheating, cooling or aerating light
substances.
LONG PITCH, SINGLE FLIGHT
Pitch is equal to 1 ½ diameters.Useful for agitating fluid materi-
als or for rapid movement ofvery freeflowing materials.
SINGLE FLIGHT RIBBON
Excellent for conveying sticky orviscous materials. Open space
between flighting and pipe elim-
inates collection and build upof the material.
VARIABLE PITCH, SINGLE FLIGHT
DOUBLE FLIGHT, STANDARD PITCH
STANDARD PITCH WITH PADDLE
PADDLE
Flights have increasing pitchand are used in screw feeders
to provide uniform with drawalof fine, freeflowing materials
over the full length of the inlet
opening.
Adjustable paddles positioned
between screw flights opposeflow to provide gentle but thor-
ough mixing action.
Double flight, standard pitchscrews provide smooth, regu-lar
material flow and uniform move-ment of certain types of materi-
als.
Adjustable paddles provide
complete mixing action, andcontrolled material flow.

CONVEYOR SCREWS
In conveying applications where extreme abrasion is a problem, WAM,Inc. hardsurfaced, conveyor screws afford an effective, practical and
economical solution. WAM, Inc. hard-surfaced screws have been uti-
lized successfully in numerous types of applications and may be ex-pected to increase normal service life over standard mild steel convey-
ors by as much as from 500 to 800%. In certain applications an evengreater degree of wear life may be obtained. To produce it s hardsur-
faced conveyors, WAM, Inc. uses a special alloy which is applied to
the carrying area of the flight face. For most typical applications, thealloy may be applied in a standard width (see table). For extreme ap-
plications, full-face application is recommended. The conveyor pipemay also be hard-surfaced. The alloy applied to a mild steel conveyor
results in a surface hardness of 58 - 62, Rockwell “C”.
WAM, Inc. ABRASION-RESISTANT SCREW CONVEYORS
Impact Resistance
The hard-facing alloy, in combination with the mild steel of the convey-or, result s in excellent impact resistance. Large, abrasive, lumpy mate
rials may be handled without undue wear, even at the conveyor inlet.
Full-face application of the flighting and pipe at the inlet will provideeven better wear life.
Versatility
Both helicoid and sectional conveyors may be hardsurfaced.
While sectional conveyors may be formed of abrasion-resistant steelson special order, hardsurfacing enables all standard or stock convey-
ors to be utilized for severely abrasive conditions. Hardsurfaced stan-dard conveyors will provide equal service at less cost and with wider
choice of conveyor sizes and types.
WAM, Inc. Quality
Maximum performance and service life from hardsurfaced conveyorscrews may be obtained only from precise application procedures.
WAM, Inc.’s conveyor screws are manufactured by personnel with ex-
tensive experience and skill in the company’s hardsurfacing technique.
WIDTH OF APPLICATION CHART
ABRASION-RESISTANT ACCESSORIESIn most cases, the conveyor screw itself is subject to the most extreme
wear. However, it is often necessary to protect hanger bearings and
coupling shafts as well. Hard-surfaced hanger bearings are designedfor use either with hardened or hardsurfaced shafts. Likewise, hard-
surfaced shafts are designed for use with hard-surfaced or hard-ironhanger bearings. Neither should ever be used with other types.
Hanger Bearings - Hard-surfaced hanger bearings are processedwith a different alloy from that used on conveyor screws. However, the
alloy offers the same outstanding characteristics. This alloy results in asurface hardness of 60-62, Rockwell “C”. In addition, it has excellent
corrosion-resistant properties, is non-toxic and has low coefficient of
friction, thus will operate without lubrication (in conjunction with hard-surfaced or hardened couplings). Numerous bearing hangers, may be
furnished with hard surfaced bearing inserts. For specific hangers avail-able with hard-surfaced inserts, refer to page 76.
Coupling Shafts - Processed with same alloy as bearings. The alloyis inlaid approximately 1/16" on the shaft by means of a special “spray”
process.The shaft is first undercut 1/16" in the bearing area. After the alloy is
applied, the hard-surfaced area is ground to the proper diameter.

DRIVE SHAFTS
WAM , Inc. screw conveyor drive shafts are manufactured from cold drawn C-1045 medium carbon steel which has an average tensilestrength of 112,000 psi. Exacting dimensional tolerances are maintained for proper bearing clearance. Coupling bolt holes are jig drilled for
perfect alignment and key seats are precision milled to insure proper assembly. For applications requiring high horsepower at low R.P.M.
resulting in torque loads exceeding the capacities of standard components. Stainless steel shafts, with an average tensile strength of 100,000psi., are also available in many types, including 304 and 316.
COUPLING SHAFT
Coupling shafts are designed to transmit rotation between individual conveyor screw sections and to provide intermediate radial support through
hanger bearings. Two basic types are available: Standard shafts, for use with hanger bearings, and close coupling shafts, designed for applica-tions where the omission of hanger bearings is desirable. Caution should be exercised in the use of close coupling shafts to prevent
deflection. WAM, Inc. coupling shafts are manufactured of cold-drawn C-1045 medium carbon steel which has an average tensile strengthof 112,000 psi. Stainless shafts, with an average tensile strength of 100,000 psi., are available in several types, including 304 and 316. All

HANGERS
HANGER BEARINGS provide intermediate radial support between separate screw sections. Since hanger bearings are designed primarily for
radial loads, 8” clearance should be allowed between the bearing and the conveyor pipe ends to prevent damage from thrust loads
transmitted by the conveyor pipe.All WAM , Inc. hangers are manufactured to exacting tolerances from the highest quality raw materials. For quick, convenient hanger
selection, the chart on page 95 relates available bearing materials to the hanger styles with which they may be used.This selection table also lists hanger materials of construction. A brief description of the various WAM, Inc., hanger styles is given on this page.
Hanger components and replacement parts are listed on pages 73 thru 75. Highly complex or specialized hanger requirements should be
referred to WAM, Inc.’s Engineering Department.
No. 216 hangers are recommend-ed for heavy-duty, abrasive appli-
cations, especially where dust-tight operation is required. No. 216
hangers may be furnished with
hard-iron, hard-surfaced or oil-im-pregnated wood bearings. When
hard iron or hard-surfaced bear-ings are used, hard iron or hard-
surfaced shafts are required. The
hanger is mounted inside, flushwith the top flanges.
No. 326 hangers are well suitedfor high temperature operation
and incorporate the basic features
of the 220 and 226. The 326 isdesigned for interior trough mount-
ing with self adjusting assemblyto compensate for unequal
thermal expansion between com-
ponents. Available only with hardiron or hard surfaced bearings.
Hardened or hard surfaced shaftsare required.
No. 220 hangers are recommend-
ed for high capacity conveyorswhere dust tight operation is not
required. Slender frame and com-pact bearing housing allow high-
er percentage of conveyor load-
ing with minimum flow obstruction.Available in all friction type bear-
ing materials. (See table, page95).
No. 30 hangers are designed for
minimum obstruction of materialflow. Bearing is supported from the
non-carrying side of the conveyorhousing. For extra support, top bar
ex tends across the trough and
bolts on both sides. Mounts flushwith trough flanges. Available in
all friction type bearing materials.(See table, page 95).
The No. 226 incorporates all the
advantages of the No. 220 but isdesigned for inside flush mount-
ing to allow dust tight operation.
available in all friction type bear-ing materials. (See table, page 95).
No. 230 hangers are designed for
heavy-duty applications wheretop mounting on the trough flang-
es is preferred. May be furnished
with either hard iron (with hardiron or hardsurfaced shafts) or
oil impregnated wood bearings.Bearing and bearing assembly
frame are readily interchange ta-
ble with No. 216 top frames.

Hanger bearing support for conveyors with tubular housings is accom-plished by means of a hanger pocket mounted on top of the housing at
hanger bearing points. The hanger bolts to the straight sides of thepocket. Any standard hanger designed for inside mounting may be
used. The pocket is sealed by a bolted access cover with weather
proof, turned-down edges. It may be gasketed for dust tight opera-tion. Standard pockets are of the same gauge as the housings to
which they are fitted.

COVERS
Flanged covers are turned down approximately 3/4" on each side.Flanges provide a limited degree of weather and dust proofing and
also may be gasketed for more complete dust or non-critical weather-proof operation. They are secured by means of bolts or screw or tog-
gle clamps.
Flat covers fit flush with housing top flanges. They may be bolted,
spring clamped or attached with screw or toggle clamps. Although flatcovers are intended primarily for interior applications, they also may
be gasketed for moderate dust-proof operation.
Standard covers for flared trough are similar to standard flanged cov-
ers except that they are fabricated specifically for flared trough. Theymay be bolted or fastened with screw or toggle clamps.
Ridged or hip roof covers are designed for outside applications. The
center peak of the cover sheds rain or snow. Both sides of the coverare flanged to provide additional weather-proofing. These covers also
may be gasketed for more severe weatherproof operation. Covers may
be bolted or attached by means of screw or toggle clamps.
The shroud cover is designed for use with standard U-trough when a
tubular cross-section is required standard covers frequently are usedwith the shroud cover to prevent accumulation of foreign matter or
moisture in the pockets formed by the contour of the shroud and the
sides of the housing.
The domed cover is intended primarily for applications where fumes orheat must be vented from the housing. Ventilation lines are readily
attached to this type cover. The domed cover is built to specifications
to suit individual requirements. Specific applications should be referredto the Engineering Department.

Feeder ShroudsShrouds are used in trough sections of screw feeders to decrease the clearance between the cover and feeder screw to obtain proper feed
regulation. Lengths are sufficient to prevent flushing of the majority of materials being handled and gauges are proportioned to trough size andgauge.

COVER SHROUDS
Conveyor Shrouds
Conveyor shroud covers are used to form a tubular cross section within the conveyor trough. This arrangement gives the features of a tubularhousing while allowing removal of the shroud for easy access and cleaning. Flat or flanged covers can be used over the shroud cover when it is
objectionable for the recess in the shroud to be exposed to dust or weather. Various types of shrouds are furnished to fit various applications.
These types are described below.
Type 1
Shroud cover has flanged sides over top rail and flanged ends at both ends. This type is used when shroud is full length of trough or betweenhangers.
Type 2
Shroud cover has flanged sides over top rails and flanged ends on one end over trough end; other end is plain. This type shroud is used at aninlet opening or next to a hanger at the plain end.
Type 3
Shroud cover has flanged sides over top rail and both ends closed and no flanges over ends. This type shroud is used between hangers.
Type 4Shroud cover has no flanges at sides or ends. Bolt holes are provided along sides, for bolting through side of trough. This allows flush mounting
with top of trough and a cover may be used over the shroud. This shroud is used mostly for short lengths when installed ahead of an inlet opening.

SPECIAL SCREW CONVEYOR WELD FINISHES
Specifications on screw conveyor occasionally include the term “grind smooth” when referring to the finish on welds. This specification is
usually used for stainless steel, but occasionally it will appear in carbon steel specifications as well.“Grind smooth” is a general term and subject to various interpretations. This section establishes WAM, Inc. recommended classes of finishes,
which should be used to help you find the class required for an application.
1 A - Weld Spatter and Slag removed (equivalent to CEMA I)
1B - Weld Spatter and Slag removed and Sand Blasted
2 A - Weld Spatter and Slag removed and rough grind welds to remove heavy weld ripple or unusual roughness (equivalent to a 40 - 50 gritfinish) (equivalent to CEMA II)
2B - Weld Spatter and Slag removed and rough grind welds to remove heavy weld ripple or unusual roughness (equivalent to a 40 - 50 grit
finish) and sandblasted
3 A - Weld Spatter and Slag removed and medium grind welds - leaving some pits and crevices (equivalent to a 80 - 100 grit finish) (equivalent
to CEMA III)
3B - Weld Spatter and Slag removed and medium grind welds - leaving some pits and crevices (equivalent to a 80 - 100 grit finish) and
sandblasted
4 - Weld Spatter and Slag removed and fine grind welds - no pits or crevices permissible (equivalent to a 140 - 150 grit finish) (equivalentto CEMA IV)
5 - Weld Spatter and Slag removed and fine grind welds - no pits or crevices permissible (equivalent to a 140 - 150 grit finish) and polishto a bright uniform finish (equivalent to CEMA V)

WAM.Inc , screw conveyor systems may be furnished as completeassemblies or in individual components. Shop Assembled Systems
are aligned and match marked for ease of assembly in the field.
These units also include all necessary hardware including bolts. Indi-vidual components should be more carefully assembled to insure
proper alignment for the most efficient operation.
NOTE: Upon delivery of conveyors, check shipment with packing lists
to be sure all components are present and not damaged. If damagehas occurred in transit, a claim should be filed with the carrier immedi-
ately.
ASSEMBLY
1. Place the conveyor housing sections in their proper sequence, us-
ing match marks or drawing. Connect the end flanges loosely. Donot tighten bolts. Align and level the housing bottom centerlines
perfectly,then tighten flange bolts.
NOTE: A conveyor assembly should always begin at the thrust end. If
the system does not require a thrust bearing unit, assembly shouldbegin at the discharge end.
2. If thrust end is designated, assemble the housing end plate andthrust bearing.
3. Insert the end or drive shaft in the bearing. Do not tighten set screws.4. Place the first conveyor screw section in the housing, slipping the
end or drive shaft into the conveyor pipe end. Secure with coupling
bolts.
IMPORTANTThe supporting lugs on the flighting should be opposite the material
carrying side of the flights. Clearance is required between the housing
ends and the conveyor pipe ends. Also be sure that the conveyor screwclears the bottom of the housing by 1/2"
5. Insert coupling shaft into the opposite end of the first screw sec-tion. Tighten coupling bolts.
6. Insert the coupling shaft through hanger bearing and bolt hanger
temporarily to the housing.
CAUTIONBefore bolting each hanger bearing in place, force all assembled screws
away from the discharge end. This removes all "slack" due to coupling
bolt hole clearance and places the conveyor screw sections longitudi-nally in the position they would assume under full thrust load during
operation. This is particularly important in long conveyors to preventthe screw pipe from contacting hanger bearings and transferring thrust
loads that would result in early failure. A minimum clearance of 1/32"
must be allowed between the conveyor pipe end and the hanger bear-ing on the side nearest the conveyor discharge. Some users prefer to
allow clearance on the inlet side by moving the hanger toward the inletend with only free running clearance between the hanger bearing and
pipe end. Reversible conveyors should have clearance between the
hanger bearing and pipe ends divided equally on each side. For con-veyors subject to high temperature materials, expansion type hangers
such as No. 326 should be used.
7. Tighten end bearing set screws firmly against the first end or drive
shaft.8. Tighten the first hanger bolts. Be sure that the hanger is at right
angles to the housing.9. Insert a coupling shaft in the second conveyor section and secure
with coupling bolts. Attach the opposite end to the coupling shaft in
the first screw section. Secure with coupling bolts. Be sure to allowthe 1/32" clearance between the hanger bearing and the pipe end
of the second section after forcing the screw sections toward theinlet end. Repeat the preceding steps for each conveyor screw
section.
11. Insert the final end or drive shaft into the last screw section andattach coupling bolts.
12.Attach the housing end and end bearing to the shaft and bolt the
end to the housing.
13.Lubricate bearings if required. CAUTION To insure there is nobinding or misalignment in the system, rotate conveyor slowly by
hand. If system is too large to turn by hand, apply power onlymomentarily and check conveyor thoroughly.
MAINTENANCE
LUBRICATIONScrew conveyor systems utilize many different designs of bearings,
therefore, lubrication requirements may vary for different systems. Ball
and roller bearings should be lubricated to manufacturers lubricationstandards. Babbitt or other type friction bearings should be lubricated
periodically. The frequency of lubrication should be based on charac-teristics of material being handled, as well as the operating conditions.
Oil-Impregnated Bronze, graphite impregnated bronze, oil impregnat-
ed wood, hard iron, hard surfaced and many types of plastic bearingsrequire no periodic lubrication.
INSPECTIONA periodic inspection of the conveyor system is recommended to in-
sure proper operation. Check for excessive wear, damaged or mis-
aligned components. The check should include intake and dischargepoints flighting thickness at the outer edge, bearing condition and align-
ment of shafts. Drive shafts are subject to the initial loads of the con-veyor, therefore, it is recommended that coupling bolts be removed
periodically to inspect for elongation of bolt holes and bent or worn
bolts.

Safety must be considered a basic factor in
machinery operation at all times. Most acci-
dents are the result of carelessness or negli-
gence. The following safety instructions are basic
guidelines and should be considered as mini-
mum provisions. Additional information shall
be obtained by the purchaser from other sourc-
es, including the American Society of Mechan-
ical Engineers, Standard ANSI B20.1, Standard
ANSI B15.1, Standard ANSI A12.1 Standard
ANSI MH4.7 and Standard ANSI Z244.
WAM, Inc., does not install equipment, conse-
quently it is the responsibility of the contractor ,
installer, owner and user to install, maintain
and operate the conveyor, components and
assemblies in such a manner as to comply with
the William-Steiger Occupational Safety and
Health Act and with all state and local laws and
ordinances and the American National Stan-
dard Institute (ANSI) safety code.
In order to avoid an unsafe or hazardous con-
dition, the assemblies or parts must be installed
and operated in accordance with the following
minimum provisions.
1. Conveyors, and all other rotating and vibrat-
ing equipment (hereafter referred to as
equipment) shall not be operated unless all
covers and/or guards for the equipment and
drive unit are in place. If the equipment is to
be opened for inspection cleaning, mainte-
nance or observation, the electric power to
the motor driving the conveyor must be
LOCKED OUT and TAGGED OUT in such a
manner that the equipment cannot be re-
started by anyone; however remote from the
area, until equipment cover or guards and
drive guards have been properly replaced.
2. If the equipment must have an open housing
as a condition of its use and application, the
entire equipment is then to be guarded by a
railing or fence in accordance with ANSI stan-
dard B20.1-1993, with special attention giv-
en to section 6.12.
3. Feed openings for shovel, front loaders or
other manual or mechanical equipment shall
be constructed in such a way that the equip-
ment opening is covered by a grating. If the
nature of the material is such that a grating
cannot be used, then the exposed
1. section of the equipment is to be guarded by
a railing or fence and there shall be a warn-
ing sign posted.
2. Do not attempt any maintenance or repairs
of the equipment until power has been
LOCKED OUT and TAGGED OUT.
3. Control stored energy: Use safety blocks be-
tween dangerous parts that could move and
injure. Always operate conveyor in accor-
dance with these instructions and those con-
tained on the caution labels affixed to the
equipment.
4. Do not place hands or feet in the equipment.
5. Never walk on equipment covers, grating or
guards.
6. Do not use equipment for any purpose other
than that for which it was intended.
7. Do not poke or prod material into the equip-
ment with a bar or stick inserted through the
openings.
8. Keep area around equipment drive and con-
trol station free of debris and obstacles.
9. Always regulate the feeding of material into
the unit at a uniform and continuous rate.
10.Do not attempt to clear jammed equipment
until power has been LOCKED OUT and
TAGGED OUT.
11.Do not attempt field modification of equip-
ment or components.
12.Equipment is not normally manufactured or
designed to handle materials that are haz-
ardous to personnel. These materials which
are hazardous include those that are explo-
sive, flammable, toxic, or otherwise danger-
ous to personnel. Equipment may be de-
signed to handle these materials. Equipment
is not manufactured or designed to comply
with local, state or federal codes for unfired
pressure vessels. If hazardous materials are
to be conveyed or if the equipment is to be
subjected to internal or external pressure,
WAM, Inc. should be consulted prior to any
modifications.
WAM, Inc. insists that disconnecting and lock-
ing out and tagging out the power to the motor
driving the unit provides this only real protec-
tion against injury. Secondary safety devices
are available; however, the decision as to their
need and the type required must be made
by the owner-assembler as we have no informa-
tion regarding plant wiring, plant environment,
the Interlocking of the equpment with other
equipment, extent of plant automation, etc.
Other devices should not be used as a substi-
tute for locking out the power prior to removing
guards or covers. We caution that use of the
secondary devices may cause employees to de-
velop a false sense of security and fail to lock
out power before removing covers or guards.
This could result in a serious injury should the
secondary device fail or malfunction.
There are many kinds of electrical devices for
interlocking of equipment and equipment sys-
tems such that if one item of equipment in a
system or process is stopped other equipment
feeding it, or following it can also be automat-
ically stopped.
Electrical controls, machinery guards, railings,
walkways, arrangement of installation, training
of personnel, etc. are necessary ingredients for
a safe working place. It is the responsibility of
the contractor, installer , owner and user to sup-
plement the materials and services furnished
with these necessary items to make the equip-
ment installation comply with the law and ac-
cepted standards.
Equipment inlet and discharge openings are
designed to connect to other equipment or
machinery so that the flow of material into and
out of the equipment is completely enclosed.
One or more caution signs as illustrated be-
low are attached to equipment housings and
equipment covers. Please order replacement
caution labels should the labels attached to
this equipment become illegible. Use Convey-
or Equipment Manufacturers Association
(CEMA) “Safety Label Brochure and Placement
Guidelines” (#201). CEMA can be contacted
