The GYRO EX bin activating feeder/discharger is a bin discharger and an accurate feeder, with up to a 100 to 1 turn down ratio, all in one piece of equipment. It produces a controlled gyratory motion to positively withdraw granular materials 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.
