Screw Conveyor Torque | Engineering Guide

Torque is measured in inch-lbs. for screw conveyor components. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be able to withstand Full Motor Torque without failing. Every KWS screw conveyor is designed to this criteria with a minimum safety factor of 5 to 1.

Types of Screw Conveyors | Engineering Guide

Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material fall back.
