It produces a controlled gyratory motion to positively withdraw granular ma- terials from bins, storage silos, and hoppers. The GYRO EX bin activating feeder/discharger uses a radial force to create a uniform circular motion on both the upper activation cone and the lower discharge cone. The stored material load is completely supported by the upper bin activation cone, which has a discharge angle less than the discharge cone. This means all material feeds faster from the lower discharge cone than from the upper bin activation cone, preventing the head load from compacting material in the lower cone as sometimes seen in traditional vibrating bin dischargers. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com Continuous Gravimetric Weigh Feeders Better-Weigh continuous feeders are ideal for gravimetric feeding of dry bulk materials where it is necessary to determine actual feed rates on a loss- of-weight basis. Available in seven models with feed rates from 1 to 550 cu ft/hr (larger sizes available), these feeders are de- signed to provide feeding in either batch or continu- ous mode depending upon the arrangement of the feeder's control electronics. In batch mode, the batch controller is used to control the fast (bulk) and slow (dribble) speeds of the feeder. Accuracies of ±0.5% can be easily achieved in 2-lb or less batches, and ±0.25% with 3-lb or greater batches with time spans of 30 to 90 seconds. In continuous mode, the feeder's electronic controller is used to constantly monitor loss of weight of material per time in order to maintain a continu- ous loss of weight with an accuracy of ±0.25% to 0.50%. Standard features include a platform or lever balance scale, sealed tactile keyboard, 7-digit numerical keyboard, automatic manual batching, and a 2- or 5-cu-ft hopper. Sanitary construction is also available. Metalfab Inc., Vernon, NJ 800-764-2999 www.metalfabinc.com Screw Feeder Meets 3-A Sanitary Standard Booth 3505 - The Volumetric Screw Feeder (VSF) and Volumetric Screw Feeder with Overflight (VSFO) meet 3-A sanitary standard 81-00. The design is appropriate for medium- to high-capacity handling of sanitary bulk materi- als. If the feed materials are non-free flowing, the VSFO model with overflighting can be used to improve feeding. Lengths for almost any application are available. Auger diameters range from 4 to 10 in. A variety of outlet options are available, including ferrules, flanges, BFM flexible sleeve fittings, and plain tube stubs. VSF and VSFO feeders are constructed of stainless steel with all product contact surfaces polished to a maximum 32Ra µin. finish. The fully de- mountable design allows for easy disassembly and cleaning.
