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

Overcoming Technical Challenges of Longer Screw Conveyors

May 19, 2014· A screw conveyor works well horizontally or on a gentle incline and should normally not have a cross-sectional load above 45 percent fill. If material fill exceeds the height of the center shaft, material can tumble back into the preceding pitch space, causing a ‘cascade effect’ as material moves backwards to the fill point.
