Syntron® Vibrating Feeders for heavy industry are ideal for feeding awide variety of bulk materials from storage piles, hoppers, bins and silos.Rugged and dependable, Syntron heavy-duty feeders are backed by yearsof 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 areideally suited for high-tonnage feeding. Feeder selection should includeconsideration of production requirements, material characteristics, andoperating environment.

Syntron Vibrating Feeders are sub-resonant tuned, two-mass, spring-connected systems. These features enable Syntron feeders to workconsistently under material damping and other varying headload conditionswith negligible changes in trough stroke. Sub-resonant tuning maintainsstroke consistency and speed stability, thus delivering higher capacitiesat controlled feed rates.

Precise, sub-resonant tuning is a key characteristic of both types ofSyntron vibrating feeders. Electromagnetic models are tuned throughcareful calculation of the number and thickness of the special leaf springsrequired to accomplish the desired tuning ratio. Electromechanical mod-els are tuned by adjusting the operating speed to obtain the exact tuningratio. Because sub-resonant tuning is so critical to feeder performance, adetailed explanation is provided for electromagnetic feeders on page 6and for electromechanical feeders on page 17.

Dependable, flexible control sets Syntron vibrating feeders apart fromother feeding and conveying machinery. Material feed rates are controlledand easily adjusted with Syntron solid-state controls; a wide range ofstandard and special models is available. Control devices can also besupplied for integration into systems that use external signals fromautomatic sensing devices. In addition, control arrangements are availablefor selecting and sequencing 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 powders to 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 main tenance asthere are no mechanical parts to wearout, such as cams, eccentrics, beltsand bearings — thus eliminatingthe need for lubrication. All move-ment is confined to the heavy-dutyleaf springs. Electrical components,such as the coil, will provide yearsof service 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 on electromagnetic feeder controls,see pages 14 and 15.)

Low sub-resonant tuning is thekey characteristic 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 its operating frequency. If the operatingfrequency is greater than the naturalfrequency, the feeder is super-resonant tuned, making it veryunstable under headload.Conversely, if the natural frequencyis greater than the operating frequency, the feeder is sub-resonanttuned, making it more consistentand stable under headload.

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 performance. Most manufacturerstune their feeders closer to reso-nance, while Syntron electromag-netic feeders are tuned furtherfrom resonance.

The operating frequency of all Syntron® Heavy-Duty ElectromagneticFeeders is checked at our test stations before shipment.

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

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

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 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 dry 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-deck multipleelectromagnetic drive units. Extra-long feeder troughs provide many advantagesin conveying materials over long distances; unlike belt conveyors, there are noidlers or pulley drive units to wear, lubricate, or replace. Long tubular troughscan convey pure, clean materials without atmospheric contamination and safelyconvey 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 wetmaterials in feeder troughs. Available only on specially designed feeders, heatedliner plates increase feeder efficiency by eliminating the downtime requiredto clean troughs. They are especially effective for materials with moisturecontents ranging from five to fifteen percent. The electric heating element isinsulated and sandwiched between two steel plates.

Syntron F-560 Electromagnetic Feeder with twodrive units.

Syntron® Electromagnetic drive units can be combined to create feeders ideally suited for specialapplications.

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.The number of drive units required is determined bythe trough width and length.

Dual-twin drive units— two sets of twin drive units,one set placed behind the other— provide bothincreased capacity and the ability to handle exceptionallyheavy loads.

The material flow rate of all multiple-drive unit modelscan be easily regulated. A special control permitsadjustment of all drive units simultaneously to controlthe flow rate of the entire feeder.

Solid-State Load Monitoring Controls

Solid-state DC signal controls accept a variable dc signal from anexternal source and use it to vary the feed rate.

Perfect for batch weighing or bagging operations. Externalscale switches connected to the control automatically signalprimary fast material flow, secondary dribble flow and instantshut-off at exactly the pre-selected weight.

Constant-stroke controls automatically maintain the trough strokeat any pre-set rate through the use of a trough-mounted inertialstroke transducer (IST).

Solid-state proportional controls permit individual material flowsettings on multiple feeders for a desired blend of materials. Amaster control potentiometer permits simultaneous flow rate regulation of all the feeders.

Remote controls permit manual adjustment of the feeder flow ratefrom a remote station located at a distance from the feeder.

Solid-state load monitoring controls sense the electrical load onprocess equipment motors to determine when the machine isapproaching an overload or underload condition and automaticallyadjust feeder output to correct machine loading.

Figure 1. Comparison of Tuning Ratios

Sub-Resonant Tuning forElectromechanical Feeders

Low sub-resonant tuning is the key char-acteristic of Syntron® electrmechanicalfeeders, making them the most stableand consistent feeders available on themarket.

Feeder tuning involves adjustment of thenatural frequency of the feeder in relationship to its operating frequency. Ifthe operating frequency is greater thanthe natural frequency, the feeder issuper-resonant tuned, making it veryunstable under headload. Conversely, ifthe natural frequency is greater than theoperating frequency, the feeder is sub-resonant tuned, making it more consistentand stable under headload.

Regardless of manufacturer, all heavy-duty,two-mass electromechanical vibratingfeeders are sub-resonant tuned. For sub-resonant tuned feeders, the distancefrom resonance is critical to feeder per-formance. Most manufacturers tune theirfeeders closer to resonance, while Syntronfeeders are tuned further from resonance.

Material damping and other variationsin headload 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 1 represents a typical competitivefeeder in a no-load state without internaldamping. Curve 2 represents a Syntronfeeder in a no-load state with internaldamping. Curve 3 represents a feederwith material headload and associateddamping. Because Syntron feeders aretuned further from resonance and are

designed with internal damping, it is evident that the loss in relative troughstroke under headload for a Syntronfeeder (Y) is negligible as compared to asubstantial loss in relative trough strokefor competitive feeders (X). This is whySyntron electromechanical feeders aremore consistent and stable than anyother feeder, even when subjected tomaterial damping and other variations in headload.

Feeder Transition HoppersFeeder capacity depends on the design of the hopper. Material character-istics 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 hopperswill substantially 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 allowsthe most 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-uniformflow pattern of material at the rear of the hopper. Material flow velocityis reduced, 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 distort drastically and will significantly reduce capacities.

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 thethroat opening. In all cases, the arc “A” should exceed 2 1/2 timesthe largest particle size.

4. Gate opening “H” must be a minimum of 2 times the largest particle of material and should increase proportionally for thedesired capacity. The most economical feeder is selected whenthe 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,resulting 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 asan adjustable front wall. Leveling blades and down stream gatesmust 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 feedertrough and skirt boards and should be a minimum of 2 1/2 timesthe 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 projectingthe angle of repose for the specific material from the gate point tothe feeder 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 andunloaded 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 runparallel to trough sides and must be reinforced to resist bulgingoutward against trough.
