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. Ruggedand 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 productivitywith high, controlled feed rates to improve cost-per-ton efficiency.Electromagnetic and electromechanical models are available. With capacityranges from 25 to 4,000 tons per hour, these feeders are ideally suited forhigh-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-connectedsystems. These features enable Syntron feeders to work consistently undermaterial damping and other varying headload conditions with negligiblechanges in trough stroke. Sub-resonant tuning maintains stroke consistencyand speed stability, thus delivering higher capacities at controlled feed rates.

Precise, sub-resonant tuning is a key characteristic of both types of Syntronvibrating feeders. Electromagnetic models are tuned through careful calcu-lation of the number and thickness of the special leaf springs required toaccomplish the desired tuning ratio. Electromechanical models are tuned byadjusting 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 electromechanicalfeeders on page 15.

Dependable, flexible control sets Syntron vibrating feeders apart from otherfeeding and conveying machinery. Material feed rates are controlled andeasily adjusted with Syntron solid-state controls; a wide range of standardand special models is available. Control devices can also be supplied forintegration into systems that use external signals from automatic sensingdevices. In addition, control arrangements are available for selecting andsequencing a group of feeders.

Syntron® Heavy-Duty Electro-magnetic Feeders come in tendifferent models with capacitiesranging from 25 to 1600 tons perhour.* These versatile feeders arecapable of handling a variety ofmaterials from the finest powdersto large, coarse particles.

Syntron Electromagnetic Feederscan be supplied in various configu-rations including multiple- driveunits and above-deck drive units.Above-deck drive units are recom-mended where there is insufficientspace below the trough.

Syntron Electromagnetic Feedersrequire minimal maintenance asthere are no mechanical parts to wearout, such as cams, eccentrics, beltsand bearings – thus eliminating theneed for lubrication. All movementis confined to the heavy-duty leafsprings. Electrical components, suchas the coil, will provide years ofservice under normal operatingconditions. Dust-tight drive unitsare standard on all models.

Dependable, flexible controls provideeasily adjustable feed rates withinstantaneous response. A varietyof controls with special controlarrangements are available.(For more information onelectromagnetic feeder controls,see pages 26 - 28.)

Sub-Resonant Tuning for Electromagnetic Feeders

Low sub-resonant tuning is the keycharacteristic of Syntron®

electromagnetic feeders, makingthem the most stable and consistentfeeders available on the market.

Feeder tuning involves adjustmentof the natural frequency of thefeeder in relationship to itsoperating frequency. If the operatingfrequency is greater than the naturalfrequency, the feeder is super-resonant tuned, making it veryunstable under headload. Conversely,if the natural frequency is greaterthan the operating frequency, thefeeder is sub-resonant tuned, makingit more consistent and stable underheadload.

Electromagnetic feeders are tunedthrough careful calculation of thenumber and thickness of the specialleaf springs required to accomplishthe desired tuning ratio.

Regardless of manufacturer, allheavy-duty, two-mass electromag-netic vibrating feeders are sub-resonant tuned. For sub-resonanttuned feeders, the distance fromresonance is critical to feeder per-formance. Most manufacturers tunetheir feeders closer to resonance,while Syntron electromagneticfeeders are tuned further fromresonance.

The natural frequency of all Syntron® Heavy-Duty Electromagnetic Feeders ischecked at our test stations before shipment.

Material damping and othervariations in headload causefluctuations in capacity and feedrates of all sub-resonant tunedfeeders. Because Syntron electro-magnetic feeders are tuned furtherfrom resonance, capacity and feedrates remain more stable and con-sistent even when the feeder issubjected to material damping andother variations in headload.

This is why Syntron electromagneticFeeders are the best solution forrugged material handlingapplications.

Electromagnetic Feeder Troughs

Syntron® Electromagnetic Feeder models FH-22 through F-88 can be furnishedwith standard flat-bottom troughs, special flat-bottom troughs or belt-centeringdischarge troughs.

Drive units can be positioned either above or below the trough. A below-deckdrive unit is most commonly used, but above-deck drive units can be suppliedfor 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 sandweighing 100 pounds per cubic foot. Capacities vary depending on drive unitlocation, 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-deckmultiple electromagnetic drive units. Extra-long feeder troughs provide manyadvantages in conveying materials over long distances; unlike belt conveyors,there are no idlers or pulley drive units to wear, lubricate, or replace. Longtubular troughs can convey pure, clean materials without atmospheric con-tamination and safely convey dusty, poisonous materials without endangeringprocessing 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 materialthat does not meet specification.

• Syntron “spreader” feeders spread a wide, even layer of material witha diagonal discharge trough or diagonal-slotted trough.

• Electrically heated trough liner plates minimize accumulation of damp orwet materials in feeder troughs. Available only on specially designed feeders,heated liner plates increase feeder efficiency by eliminating the downtimerequired to clean troughs. They are especially effective for materials withmoisture contents ranging from five to fifteen percent. The electric heatingelement 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 forElectromechanical Feeders

Low sub-resonant tuning is the key char-acteristic of Syntron® electromechanicalfeeders, making them the most stable andconsistent feeders available on the market.

Feeder tuning involves adjustment of thenatural frequency of the feeder in relation-ship to its operating frequency. If theoperating frequency is greater than thenatural frequency, the feeder is super-resonant tuned, making it very unstableunder headload. Conversely, if the naturalfrequency is greater than the operatingfrequency, the feeder is sub-resonant tuned,making it more consistent and stable underheadload.

Regardless of manufacturer, all heavy-duty,two-mass electromechanical vibratingfeeders are sub-resonant tuned. For sub-resonant tuned feeders, the distance fromresonance is critical to feeder performance.Most manufacturers tune their feederscloser to resonance, while Syntron feedersare tuned further from resonance.

Material damping and other variations inheadload cause fluctuations in capacityand feed rates of all sub-resonant tunedfeeders. Because Syntron electromechanicalfeeders are tuned further from resonance,capacity and feed rates remain more stableand consistent even when the feeder issubjected to material damping and othervariations in headload. In addition, Syntronelectromechanical feeder design incorpo-rates internal damping, which contributesto their stability and consistency.

On the comparison chart (Figure 1), curve 1represents a typical competitive feeder ina no-load state without internal damping.Curve 2 represents a Syntron feeder in ano-load state with internal damping.Curve 3 represents a feeder with materialheadload and associated damping.Because Syntron feeders are tuned furtherfrom resonance and are designed with

internal damping, it is evident that theloss in relative trough stroke under head-load for a Syntron feeder (Y) is negligibleas compared to a substantial loss in relativetrough stroke for competitive feeders (X).This is why Syntron electromechanicalfeeders are more consistent and stable thanany other feeder, even when subjected tomaterial damping and other variations inheadload.

Feeder Transition HoppersFeeder capacity depends on the design of the hopper. Material characteris-tics such as size distribution, shear properties and cohesiveness generallydictate the configuration of feeder transition hoppers. Material flowvelocities vary, depending upon material properties, feeder stroke andoperating speed.

Good transition hopper design optimizes flow rate, resulting in the mosteconomical choice of a feeder. Improperly designed transition hoppers willsubstantially reduce feeder capacities.

Figure 1 illustrates Ideal and Acceptable Hopper designs.The Ideal Hopperwith a throat (T) to gate height (H) ratio of 0.6 shows a uniform materialflow pattern to the feeder trough. Material at the front and rear of thehopper moves at nearly the same velocity, and the discharge depth (d) isnearly equal to the hopper gate height. The Ideal Hopper design allows themost economical feeder to be used.

The Acceptable Hopper design may require a slightly larger feeder thanrequired for the Ideal Hopper design. This is due to the non-uniform flowpattern of material at the rear of the hopper. Material flow velocity isreduced, material depth “d” is reduced and there is a reduction in feedercapacity. A T/H ratio of 0.6 to 1.0 is generally acceptable. However, whenthe T/H ratio exceeds this range, the material flow patterns distortdrastically and will significantly reduce capacities.

Recommended Designs for Hoppers and Transitions

C (tph) =

T = Throat GF = Gate FactorH = Gate Height Opening R = Flow Rate (ft/min) � See ChartC = 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 slopeincreases 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 buildupat inlet

� Reduced potential for spillage at backand sides

� Reduced material load on feeder



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 aminimum of 2 times the largest particle of material. For particlesthat are nearly the same size (near size), “T” should be a minimumof 4 times the largest particle size to prevent blockage at the throatopening. In all cases, the arc “A” should exceed 2 1/2 times thelargest particle size.

4. Gate opening “H” must be a minimum of 2 times the largestparticle of material and should increase proportionally for thedesired capacity. The most economical feeder is selected when thethroat dimension “T” is equal to or slightly larger than H/2. If “T” isgreater 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 thehopper’s 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 anadjustable front wall. Leveling blades and down stream gates mustnot be used. Horizontal cut off gates should be used to performfeeder 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 andskirt boards and should be a minimum of 2 1/2 times the largestparticle size. For near size material the width of “D” should be aminimum of 4 times the largest particle size.

7. The minimum length of the feeder is determined by projecting theangle of repose for the specific material from the gate point to thefeeder pan and adding approximately 6 inches.

8. The feeder must not contact any adjacent structure but must befree to vibrate. Allowance must be made for a decrease in feederelevation of approximately 2 inches, due to static material load. Inaddition, 1 inch minimum clearance at sides and 1 1/2 inches atbottom and back must be maintained in both loaded and unloadedconditions.

9. The skirts must taper in the direction of flow (diverge fromconveying surface) to prevent material from jamming and causingadditional problems such as spillage and build-up. Skirts must runparallel to trough sides and must be reinforced to resist bulgingoutward against trough.
