Screw Conveyor Inlet Spouts

Inlet spouts are typically located at one end of a screw conveyor on the top of the cover. Bulk materials enter a screw conveyor through the inlet spout. Multiple inlet spouts can be used to feed a screw conveyor. The screw conveyor must be designed for the total volumetric feed rate of all of the inlets combined.
