Syntron Heavy-Duty Vibrating Feeders

Syntron Vibrating Feeders for heavy industry are ideal for feeding a widevariety of bulk materials from storage piles, hoppers, bins and silos. Rugged

and dependable, Syntron heavy-duty feeders are backed by years of service-

proven performance in the mining, aggregates, glass, cement, chemical,

wood products and steel industries.

Syntron Vibrating Feeders are designed to increase bulk handling productivity

with high, controlled feed rates to improve cost-per-ton efficiency.

Electromagnetic and electromechanical models are available. With capacity

ranges from 25 to 4,000 tons per hour, these feeders are ideally suited for

high-tonnage feeding. Feeder selection should include consideration of pro-

duction requirements, material characteristics, and operating environment.

Syntron Vibrating Feeders are sub-resonant tuned, two-mass, spring-connected

systems. These features enable Syntron feeders to work consistently under

material damping and other varying headload conditions with negligible

changes in trough stroke. Sub-resonant tuning maintains stroke consistency

and speed stability, thus delivering higher capacities at controlled feed rates.

Precise, sub-resonant tuning is a key characteristic of both types of Syntron

vibrating feeders. Electromagnetic models are tuned through careful calcu-

lation of the number and thickness of the special leaf springs required to

accomplish the desired tuning ratio. Electromechanical models are tuned by

adjusting the operating speed to obtain the exact tuning ratio. Because sub-

resonant tuning is so critical to feeder performance, a detailed explanationis provided for electromagnetic feeders on page 6 and for electromechanical

feeders on page 15.

Dependable, flexible control sets Syntron vibrating feeders apart from other

feeding and conveying machinery. Material feed rates are controlled and

easily adjusted with Syntron solid-state controls; a wide range of standard

and special models is available. Control devices can also be supplied for

integration into systems that use external signals from automatic sensing

devices. In addition, control arrangements are available for selecting and

sequencing a group of feeders.

Syntron Heavy-Duty Electromagnetic Feeders

Bulk material feeding with full-range control.

Syntron

Heavy-Duty Electro-magnetic Feeders come in ten

different models with capacities

ranging from 25 to 1600 tons per

hour.* These versatile feeders are

capable of handling a variety of

materials from the finest powders

to large, coarse particles.

Syntron Electromagnetic Feeders

can be supplied in various configu-

rations including multiple- drive

units and above-deck drive units.Above-deck drive units are recom-

mended where there is insufficient

space below the trough.


require minimal maintenance as

there are no mechanical parts to wear

out, such as cams, eccentrics, belts

and bearings thus eliminating the

need for lubrication. All movement

is confined to the heavy-duty leaf

springs. Electrical components, suchas the coil, will provide years of

service under normal operating

conditions. Dust-tight drive units

are standard on all models.

Dependable, flexible controls provide

easily adjustable feed rates with

instantaneous response. A variety

of controls with special control

arrangements are available.

Sub-Resonant Tuning for Electromagnetic Feeders

Low sub-resonant tuning is the key

characteristic of Syntron

electromagnetic feeders, making

them the most stable and consistent

feeders available on the market.

Feeder tuning involves adjustment

of the natural frequency of the

feeder in relationship to its

operating frequency. If the operating

frequency is greater than the natural

frequency, the feeder is super-

resonant tuned, making it very

unstable under headload. Conversely,

if the natural frequency is greater

than the operating frequency, the

feeder is sub-resonant tuned, making

it more consistent and stable under

headload.

Electromagnetic feeders are tuned

through careful calculation of the

number and thickness of the special

leaf springs required to accomplish

the desired tuning ratio.

Regardless of manufacturer, all

heavy-duty, two-mass electromag-

netic vibrating feeders are sub-

resonant tuned. For sub-resonant

tuned feeders, the distance from

resonance is critical to feeder per-

formance. Most manufacturers tune

their feeders closer to resonance,

while Syntron electromagnetic

feeders are tuned further from

resonance.

The natural frequency of all Syntron Heavy-Duty Electromagnetic Feeders is

checked at our test stations before shipment.

Material damping and other

variations in headload cause

fluctuations in capacity and feed

rates of all sub-resonant tuned

feeders. Because Syntron electro-

magnetic feeders are tuned further

from resonance, capacity and feed

rates remain more stable and con-

sistent even when the feeder is

subjected to material damping and

other variations in headload.

This is why Syntron electromagnetic

Feeders are the best solution for

rugged material handling

applications.

Electromagnetic Feeder Troughs

Syntron Electromagnetic Feeder models FH-22 through F-88 can be furnished

with standard flat-bottom troughs, special flat-bottom troughs or belt-centering

discharge troughs.

Drive units can be positioned either above or below the trough. A below-deck

drive unit is most commonly used, but above-deck drive units can be supplied

for installations where there is insufficient space below the trough. However,

an above-deck drive unit may reduce feeder capacity slightly.

Capacities for feeder models with standard troughs are based on sand

weighing 100 pounds per cubic foot. Capacities vary depending on drive unit

location, material characteristics, material density, trough length and width,

trough liner type, feeder installation, skirt boards and hopper transitions.

Several trough options are available for special applications. Syntron extra-

long feeder troughs can be supplied with either below-deck or above-deck

multiple electromagnetic drive units. Extra-long feeder troughs provide many

advantages in conveying materials over long distances; unlike belt conveyors,there are no idlers or pulley drive units to wear, lubricate, or replace. Long

tubular troughs can convey pure, clean materials without atmospheric con-

tamination and safely convey dusty, poisonous materials without endangering

processing personnel.

Other trough options include:

Syntron vibrating inspection tables feed material forward at a smooth,

controlled rate of flow. This enables an operator to remove material

that does not meet specification.

Syntron spreader feeders spread a wide, even layer of material with

a diagonal discharge trough or diagonal-slotted trough.

Electrically heated trough liner plates minimize accumulation of damp or

wet materials in feeder troughs. Available only on specially designed feeders,

heated liner plates increase feeder efficiency by eliminating the downtime

required to clean troughs. They are especially effective for materials with

moisture contents ranging from five to fifteen percent. The electric heating

element is insulated and sandwiched between two steel plates.

Sub-resonant Tuning for Electromechanical Feeders

Stroke consistency and speed stability for high-capacity feeding.



Figure 1. Comparison of Tuning Ratios

Sub-Resonant Tuning for

Electromechanical Feeders

Low sub-resonant tuning is the key char-

acteristic of Syntron electromechanical

feeders, making them the most stable and

consistent feeders available on the market.

Feeder tuning involves adjustment of the

natural frequency of the feeder in relation-

ship to its operating frequency. If the

operating frequency is greater than the

natural frequency, the feeder is super-

resonant tuned, making it very unstable

under headload. Conversely, if the natural

frequency is greater than the operating

frequency, the feeder is sub-resonant tuned,

making it more consistent and stable under

headload.

Regardless of manufacturer, all heavy-duty,

two-mass electromechanical vibrating

feeders are sub-resonant tuned. For sub-

resonant tuned feeders, the distance from

resonance is critical to feeder performance.

Most manufacturers tune their feeders

closer to resonance, while Syntron feeders

are tuned further from resonance.

Material damping and other variations in

headload cause fluctuations in capacity

and feed rates of all sub-resonant tunedfeeders. Because Syntron electromechanical

feeders are tuned further from resonance,

capacity and feed rates remain more stable

and consistent even when the feeder is

subjected to material damping and other

variations in headload. In addition, Syntron

electromechanical feeder design incorpo-

rates internal damping, which contributes

to their stability and consistency.

On the comparison chart (Figure 1), curve 1

represents a typical competitive feeder ina no-load state without internal damping.

Curve 2 represents a Syntron feeder in a

no-load state with internal damping.

Curve 3 represents a feeder with material

headload and associated damping.

Because Syntron feeders are tuned further

from resonance and are designed with

internal damping, it is evident that the

loss in relative trough stroke under head-

load for a Syntron feeder (Y) is negligible

as compared to a substantial loss in relative

trough stroke for competitive feeders (X).

This is why Syntron electromechanical

feeders are more consistent and stable than

any other feeder, even when subjected tomaterial damping and other variations in

headload.

RF Medium-Duty Electromechanical Feeders

These master material movers can feed it all.

Two Syntron RF medium-duty electromechanical feeders

feeding coal onto a belt conveyor.

Syntron RF Medium-Duty Electromechanical

Vibrating Feeders meet the varying, mid-range

bulk material handling needs of industry.

Capable of handling a wide range of materials,

these two models provide feed rate capacities

from 400 to 600 tons per hour.*

Syntron RF feeders are two-mass vibrating units;

the trough is one mass and the exciter unit is

the other. The exciter is belt-driven by a standard-

frame induction motor and connected to the

trough with long-life polymeric shear springs.The ball bearings in the exciter unit have a

minimum life expectancy of 20,000 L10 hours.

Variable pitch motor sheaves provide a positive

method of tuning. This Syntron design permits

higher feed capacities from smaller trough sizes,

enabling you to select a more economical unit to

meet your capacity requirements.

Variable operating speeds and trough stroke,

combined with the damping characteristics of

polymeric shear springs, are significant factors

in the performance capabilities of Syntron RF

Medium-Duty Electromechanical Feeders.

All Syntron RF Feeder motors are labeled for

inverter duty and vibration service and are

furnished with a cast-iron frame. Special motors

can be supplied to meet UL explosion-proof

requirements.

* Based on dry sand weighing 100 pounds per

cubic foot. Capacities vary depending on

material density, trough liner type, trough

length, trough width, hopper transitions and

skirt board arrangement.

MF Heavy-Duty Electromechanical Feeders

The high-capacity performers.

Syntron MF Heavy-Duty Electromechanical Feeders are

the heavy-weights of bulk material handling and areused for higher capacity requirements. The eight heavy-

duty models handle capacities from 600 to 4,000 tons

per hour.*

Syntron Heavy-Duty Electromechanical Feeders combine

extra structural strength with durable components. The

deep wing plates form a bridge between inlet and dis-

charge suspension supports, providing extra strength for

years of dependable service. Standard troughs feature

unitized weldments one-piece, completely welded

units for greater strength. Troughs are also available

with bolt-together construction for tunnel installationsor other confined areas.

MF Heavy-Duty Electromechanical Feeders are two-mass,

spring-connected and sub-resonant-tuned. The exciter

unit is connected to the trough with corrosion resistant

polymeric springs, which are more stable under varying

conditions. The springs are compressed for improved

load stability, improved feed angles and straight line

motion. The spring design eliminates pinch points, an

important safety feature. Exciters in these heavy-duty

feeders use double roll, spherical roller bearings, with

L10 expectancies up to 140,000 hours.

All Syntron MF Electromechanical Feeder motors are

labeled for inverter duty and vibration service. Special

motors can be supplied to meet UL explosion-proof

requirements.

Attachments for safety cables are included on all

Syntron MF feeders.

Syntron Crusher Loading Feeder

The new Syntron Crusher Loading Feeder is a traditional mechanical style

vibratory feeder with a peripheral discharge. The Crusher Loading Feeder

retains the high reliability and robust design of the mechanical feeder; the

peripheral discharge, which has its origins in distribution of snack foods and

cereals onto radial scales, enables equal distribution of fine and coarse product.

The trough is fully lined to account for wear, and it is suspended by the same

method as traditional vibratory feeders. The suspension framework is mounted

on a trolley that can simply be moved out of the way for crusher maintenance.

In side-by-side installations of a feeder-plus-rotary distributor and a Syntron

Crusher Loading Feeder directly feeding the crusher, the Crusher Loading

Feeder delivered superior, cone-friendly performance. The specially configured

discharge blended fines and coarse materials to provide uniform distribution

of material to the cone.

In addition to the savings potential of reduced capital equipment costs, the

Syntron Crusher Loading Feeder provides easy installation and maintenanceaccessibility. Like all Syntron feeders, the Crusher Loading Feeder is sub-

resonant tuned and incorporates linear feed rate control to improve bulk

handling productivity. It can be sized to match application requirements.

For more information, call 1-800-356-4899 and ask to speak with one of

our applications specialists.

Feeder Transition Hoppers

Feeder capacity depends on the design of the hopper. Material characteris-

tics such as size distribution, shear properties and cohesiveness generally

dictate the configuration of feeder transition hoppers. Material flow

velocities vary, depending upon material properties, feeder stroke and

operating speed.

Good transition hopper design optimizes flow rate, resulting in the most

economical choice of a feeder. Improperly designed transition hoppers will

substantially reduce feeder capacities.

Figure 1 illustrates Ideal and Acceptable Hopper designs.The Ideal Hopper

with a throat (T) to gate height (H) ratio of 0.6 shows a uniform material

flow pattern to the feeder trough. Material at the front and rear of the

hopper moves at nearly the same velocity, and the discharge depth (d) is

nearly equal to the hopper gate height. The Ideal Hopper design allows the

most economical feeder to be used.

The Acceptable Hopper design may require a slightly larger feeder than

required for the Ideal Hopper design. This is due to the non-uniform flow

pattern of material at the rear of the hopper. Material flow velocity is

reduced, material depth d is reduced and there is a reduction in feeder

capacity. A T/H ratio of 0.6 to 1.0 is generally acceptable. However, when

the T/H ratio exceeds this range, the material flow patterns distort

drastically and will significantly reduce capacities.

Recommended Designs for Hoppers and Transitions

T = Throat GF = Gate Factor

H = Gate Height Opening R = Flow Rate (ft/min) See Chart

C = Capacity W = Feeder Width (inches)

d = Depth of Flow at Discharge

Flow Rate - R (ft/min)

Suggested Electromagnetic SizeIf material size is -4-in with a trough down slope of up to 10

, use 30-40 ft/min.

If material size is +4-in to -12-in with a trough down slope of up to 10 , use 25-30 ft/min.If material size is +12-in with a trough down slope of up to 10 , use 20-30 ft/min.Suggested Electromechanical SizeIf material size is -4-in with a trough down slope of up to 10 , use 50-60 ft/min.If material size is +4-in to -12-in with a trough down slope of up to 10 , use 45-55 ft/min.If material size is +12-in with a trough down slope of up to 10 , use 40-50 ft/min.

Feeder down slope usually effects flow rate by 2% per degree. As down slope

increases flow rate increases. As down slope decreases flow rate decreases.

Ideal Hopper Promotes:

Uniform flow pattern

Maximum capacity

Maximum material velocity

Maximum material depth

Optimized feeder size

Reduced potential for material buildup

at inlet

Reduced potential for spillage at back

and sides

Reduced material load on feeder


33/40



Refer to Figure 2.

1. Rear wall angle steep enough to permit material flow (60 5).

2. Front wall angle just enough to permit material flow (55 5).

3. The throat dimension T for random size material should be a

minimum of 2 times the largest particle of material. For particles

that are nearly the same size (near size), T should be a minimum

of 4 times the largest particle size to prevent blockage at the throat

opening. In all cases, the arc A should exceed 2 1/2 times the

largest particle size.

4. Gate opening H must be a minimum of 2 times the largest

particle of material and should increase proportionally for the

desired capacity. The most economical feeder is selected when the

throat dimension T is equal to or slightly larger than H/2. If T is

greater than H the flow pattern of the material is disturbed, result-

ing in non-uniform flow.

5. When adjustable gates are used, the gate must be parallel to the

hoppers front wall and must be as close to the front wall as possible.

The separation must not exceed 2 inches. The gate should act as an

adjustable front wall. Leveling blades and down stream gates must

not be used. Horizontal cut off gates should be used to perform

feeder maintenance and must not be used to regulate flow.

6. The inside width of the opening D (between stationary skirtboards)

should allow for a 1-inch clearance between the feeder trough and

skirt boards and should be a minimum of 2 1/2 times the largest

particle size. For near size material the width of D should be a

minimum of 4 times the largest particle size.7. The minimum length of the feeder is determined by projecting the

angle of repose for the specific material from the gate point to the

feeder pan and adding approximately 6 inches.

8. The feeder must not contact any adjacent structure but must be

free to vibrate. Allowance must be made for a decrease in feeder

elevation of approximately 2 inches, due to static material load. In

addition, 1 inch minimum clearance at sides and 1 1/2 inches at

bottom and back must be maintained in both loaded and unloaded

conditions.

9. The skirts must taper in the direction of flow (diverge from

conveying surface) to prevent material from jamming and causingadditional problems such as spillage and build-up. Skirts must run

parallel to trough sides and must be reinforced to resist bulging

outward against trough.
