Composite feeder, loss in weight system

Scientific Marketing Services offers loss-in- weight feeder manufactured by Vibra Screw, Inc., The AccuFeed loss-in- weight system minimises loss of accuracy during the volumetric refill cycle by incorporating controlled vibration of the feeder. Controlled vibration also improves accuracy in the gravimetric mode where the weight signal is far more stable than in other designs. The product"s list price is significantly lower than comparable steel loss in weight feed systems. The plastic feeder is easily custom adapted to a broad range of applications by adding a secondary trough conditioning screw for nonfree flowing materials. State of the art microprocessor controls incorporate user-friendly, menu driven software. Membrane keyboards and easy to read displays support a revolutionary concept of distinguishing actual weight from plant electronic noise. The feeder offers sizes from 1" to 6" screw diameters, and capacities from 2.8 to over 600 ft3/hr. The units are constructed of food grade polyethylene, which is inert and noncorrosive. Food grade polyethylene is unaffected by most acidic or caustic agents. These sanitary designs allow easy cleaning between material changes and versatility in hopper selection. These adapt easily to a variety of storage/discharge systems. The company also offers the AccuFeed as a standard volumetric feeder. The company also manufactures a wide range of equipment for feeding and metering dry materials. The company"s products and systems also include bin activators, bag fillers, volumetric screw and belt feeders, all types of gravimetric feeders, bulk bag unloaders, blenders, and electronic controls.
