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 …

how to make a flat pattern of a flight of screw conveyor ...

2007-6-26 · It is done by drawing two ellipses one centered in the other. One ellipse is the width of the thickness of the root diameter of the screw with a length that fits the root diameter at the pitch you want to gain per cycle. The other width diameter is the inside diameter of the tube the screw runs in less some clearance.
