Screw Conveyor Capacity Engineering Guide

A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and
