Spiroflow Systems, Inc.: Pneumatic Feeder Systems
March 19, 2002
Spiroflow Systems, Inc. has introduced an improved series of pneumatic feeders for use in Pneuvac(R) vacuum conveyor systems. Pneuvac PF series pneumatic feeders use air to safely convey powder materials to distances up to 300 ft (91.44 m). Unlike conveyors that come in contact with the material being conveyed, this system is less friable and keeps powder degradation to a minimum. The company custom designs the systems to economically and hygienically convey powder at rates up to 12,000 lbs/hr (5500 kg/hr). The process feeder (PF) design is available with several different diameters and filter areas to meet specific needs and conveying capacities. When fitted with a flapper type discharge gate, the PF series is ideal for hopper loading applications. Conveying is accomplished on a cycling fill/dump principle. When equipped with a rotary airlock, conveying is continuous.
