The VSH Hopper stores and volumetrically discharges regrind ranging from 1 lb. to 15 lbs. per cubic foot. The unique design has a cylindrical storage section with a fully swept flat bottom to assure no bridging in the hopper. The sweep arms are driven by a high torque, low RPM planetary reducer which continuously undermines material from the bottom. It in turn feeds the variable speed discharge screw conveyor, allowing material to descend uniformly. This design is a significant improvement over “U” shaped or cone bottomed hopper designs that cause regrind to bridge, pack, and rat-hole. The VSH Hopper can be designed to accommodate any feed rate as well as a wide range of storage capacities without increasing overall height.
