Syntron ® Electromechanical FeedersSyntron ® Electromechanical FeedersIncrease bulk handling productivity with controlled high feed rate units.Syntron ® Heavy-Duty Electromechanical Feedersare available in a number of models with capacitiesranging from 400 to 4,000 tons per hour.* Abovedeckdrive units are available, but will provideslightly lower capacities.Syntron Electromechanical Feeders are ruggedlyconstructed to reduce maintenance and improveproduction efficiency.ControlsDependable, flexible solid-state control sets Syntronheavy-duty feeders apart from other feeding andconveying machinery. Feed rates are easily adjusted.Response is instantaneous. Control devices can besupplied for integration in systems using externalsignals from automatic sensing devices in instruments.Special control arrangements are also available forselecting and sequencing a group of feeders.Variable frequency controls for RF and MF feedersprovide linear feed rate and are available for eitherlocal or remote control operation. Control componentsare enclosed in a sturdy wall-mounted enclosure,and are available in general purpose, dust-tight,watertight or explosion-proof construction. Formore information about electromechanical feedercontrols, see page 29.Trough SelectionFeeder troughs for RF and MF feeders are one-pieceunitized weldments providing a rigid durable troughto meet application requirements. Troughs withbolt-together construction are available for tunnelinstallations or other confined areas.Standard finish includes High Solids Enamel Paint,International Red, 2.0 to 3.0 mils D.F.T. Stainlesssteel troughs are also available. Special coatingsand trough liners are available options to satisfyapplication requirements.Syntron ® RF-120 Electromechanical Feeder handles mediumloads.Syntron MF-200 Electromechanical Feeder feeding rock fromprimary crusher to belt conveyor.* Based on sand weighing 100 pounds per cubic foot.Capacities vary depending on material density, troughliner type, trough length, trough width, hoppertransitions and skirt board arrangement.14
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
