Syntron Heavy-Duty Vibrating Feeders

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 handlingproductivity with high, controlled feed rates to improve cost-per-tonefficiency. 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 modelsare 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 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 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 onelectromagnetic feeder controls,see pages 14 and 15.)

Syntron ElectromagneticFeeders are normally installedby suspension mounting withfour flexible wire rope cables.They can also be supplied forbase mounting on a solid base,or with a combination of basemounting and suspensionmounting.

Syntron Electromagnetic Feeders are ideal for use in a stationary operation suchas a tunnel system from a surge pile. They are usually controlled from a remotepoint to provide the desired feed rate. In this application,a model FH-22 feeds limestone to a belt conveyor.

Sub-Resonant Tuning for Electromagnetic Feeders

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 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 frequencyis greater than the operatingfrequency, 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 electro-magnetic vibrating feeders aresub-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 operating frequency of all Syntron Heavy-Duty Electromagnetic Feedersis checked 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 andconsistent 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 TroughsSyntron Electromagnetic Feeder models FH-22 through F-88 can be fur-nished with standard flat-bottom troughs, special flat-bottom troughs orbelt-centering discharge 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 besupplied 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-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

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 stableand consistent feeders available on themarket.

Feeder tuning involves adjustment of thenatural frequency of the feeder inrelationship to its operating frequency.If the operating frequency is greaterthan the 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 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 electromechan-ical feeders are tuned further from reso-nance, capacity and feed rates remainmore stable and consistent even when thefeeder is subjected to material dampingand other variations in headload. Inaddition, Syntron electromechanicalfeeder design incorporates internaldamping, which contributes to theirstability 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 associated

damping. Because Syntron feeders aretuned further from resonance and aredesigned with internal damping, it isevident 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 variationsin headload.

Syntron RF Medium-Duty ElectromechanicalVibrating Feeders meet the varying, mid-rangebulk material handling needs of industry.Capable of handling a wide range of materials,these two models provide feed rate capacitiesfrom 100 to 600 tons per hour.*

Syntron RF feeders are two-mass vibratingunits; the trough is one mass and the exciterunit is the other. The exciter is belt-driven by astandard-frame induction motor and connectedto the trough with long-life polymeric shearsprings. The ball bearings in the exciter unithave a minimum life expectancy of 20,000 L10hours.

Variable pitch motor sheaves provide a positivemethod of tuning. This Syntron design permitshigher feed capacities from smaller troughsizes, enabling you to select a more economicalunit to meet your capacity requirements.

Variable operating speeds and trough stroke,combined with the damping characteristics ofpolymeric shear springs, are significant factorsin the performance capabilities of Syntron RFMedium-Duty Electromechanical Feeders.

All Syntron RF Feeder motors are labeled forinverter duty and vibration service and arefurnished with a cast-iron frame. Special motorscan be supplied to meet UL explosion-proofrequirements.

Remote Control

Solid-State Proportional Controls

Variable-frequency controls offer total feed rate regulation throughadjustment of a potentiometer knob or PLC.

Two-Rate Automatic Scale controls are perfect for batch weighing orbagging operations. External scale switches connected to the controlautomatically signal primary fast material flow, secondary dribble flowand instant shut-off at exactly the pre-selected weight.

Solid-state proportional controls permit individual material flow set-tings on multiple feeders for a desired blend of materials. A mastercontrol potentiometer permits simultaneous flow rate regulation of allthe feeders.

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

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 distortdrastically and will significantly reduce capacities.

Flow Rate - R (ft/min)Suggested Electromagnetic SizeIf material size is -4-in with a trough down slope of 10, use 35 ft/min.If material size is +4-in to -12-in with a trough down slope of 10, use 30 ft/min.If material size is +12-in with a trough down slope of 10, use 25 ft/min.Suggested Electromechanical SizeIf material size is -4-in with a trough down slope of 10, use 55 ft/min.If material size is +4-in to -12-in with a trough down slope of 10, use 50 ft/min.If material size is +12-in with a trough down slope of 10, use 45 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

Recommended installation



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 largestparticle 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. IfT 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 thehoppers 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 toperform 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 Dshould 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 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.
