Heavy-Duty FeedersIncrease bulk handling productivity with controlledhigh feed rates that improve cost-per-ton handlingefficiency.

Syntron ® Heavy-Duty Vibrating FeedersSyntron ® 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 serviceprovenperformance 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 productionrequirements, 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 calculationof 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 subresonanttuning 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.Electromagnetic FeederSyntron ® F-SeriesElectromagnetic FeederElectromechanical FeedersSyntron ® MF ElectromechanicalFeederSyntron ® RF ElectromechanicalFeederMaterial Handling Solutions3www.fmctechnologies.com/materialhandling

Syntron ® Electromagnetic Feeders (cont’d.)Sub-Resonant Tuning for Electromagnetic FeedersLow 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 superresonanttuned, 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 electromagneticvibrating feeders are subresonanttuned. For sub-resonanttuned feeders, the distance fromresonance is critical to feeder performance.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 electromagneticfeeders are tuned furtherfrom resonance, capacity and feedrates remain more stable and consistenteven when the feeder issubjected to material damping andother variations in headload.This is why Syntron electromagneticFeeders are the best solution forrugged material handlingapplications.6

Syntron ® Electromagnetic Feeders (cont’d.)Electromagnetic Feeder TroughsSyntron ® 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 ® extralongfeeder 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 contaminationand 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.Diagonal discharge spreader feeder.Standard flat-bottom trough,below-deck drive unit.Tubular trough, below-deck driveunit.Flat bottom trough, above-deckdrive unit.Other Trough Options Include:■ Covered Trough with Dust Seals■■■■Open Trough with Dust SealsScreening FeedersDiagonal Discharge TroughBelt-Centering Discharge TroughTrough Liner Options Include:■ T-1A■■AR-400AR-500■ Stainless Steel■■■■UHMW PlasticRubberCeramicCarbide Overlay12

Multiple-Drive Unit Electromagnetic FeedersSyntron ® Electromagnetic drive units can be combinedto create feeders ideally suited for special applications.Multiple-drive units, positioned one behind the other,result in a long, vibrating conveyor. When an especiallywide material layer is desired, multiple-drive units canbe placed side by side on extra wide feeder troughs. Thenumber of drive units required is determined by thetrough width and length.Dual-twin drive units – two sets of twin drive units, oneset placed behind the other – provide both increasedcapacity and the ability to handle exceptionally heavy loads.The material flow rate of all multiple-drive unit modelscan be easily regulated. A special control permits adjustmentof all drive units simultaneously to control theflow rate of the entire feeder.Sixteen foot, triple drive unit Syntron ® F-440Electromagnetic Feeder conveyor.Syntron F-560 Electromagnetic Feeder with twodrive units.Electromagnetic drive units with tubular trough.An eight-foot wide by twenty-four inch long troughpowered by four Syntron F-330 electromagnetic driveunits.A selection of some of the available multiple-drive unitconfigurations.Material Handling Solutions13www.fmctechnologies.com/materialhandling

Sub-resonant Tuning for Electromechanical FeedersStroke consistency and speed stability for high-capacity feeding.Low sub-resonant tuning is the key characteristicof Syntron ® electromechanicalfeeders, making them the most stable andconsistent feeders available on the market.Feeder tuning involves adjustment of thenatural frequency of the feeder in relationshipto its operating frequency. If theoperating frequency is greater than thenatural frequency, the feeder is superresonanttuned, 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 subresonanttuned 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 incorporatesinternal 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 withSub-Resonant Tuning forElectromechanical FeedersFigure 1. Comparison of Tuning Ratiosinternal damping, it is evident that theloss in relative trough stroke under headloadfor 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.Material Handling Solutions15www.fmctechnologies.com/materialhandling

Recommended InstallationRecommended Designs for Hoppers and TransitionsFeeder Transition HoppersFeeder capacity depends on the design of the hopper. Material characteristicssuch 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.T = ThroatGF = Gate FactorH = Gate Height Opening R = Flow Rate (ft/min) ◆ See ChartC = CapacityW = Feeder Width (inches)d = Depth of Flow at DischargeCapacity (tons per hour) x 4800d (in) =[W (in) - 4 (in)] x R (ft/min) x D (lb/ft 3 )C (tph) =[W (in) - 4 (in)] x R (ft/min) x D (lb/ft 3 ) x d (in)4800H (in) = GF x d (in)◆ 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.Figure 1. Hopper DesignIdeal 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 feederFeeder down slope usually effects flow rate by 2% per degree. As down slopeincreases flow rate increases. As down slope decreases flow rate decreases.30

Recommended Hopper Design and Feeder SelectionRefer 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, resultingin 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.Figure 2.
