Screw Conveyor Horsepower Engineering Guide

Horsepower is defined as the power required to safely and feasibly convey a bulk material a fixed distance in a screw conveyor. The horsepower required to drive a screw conveyor is called Total Shaft Horsepower, or TSHP. TSHP is a function of the characteristics of the bulk material being conveyed and the friction inherent in the screw conveyor. It is very important to design a screw conveyor

Screw Conveyor Engineering Guide Horsepower Calculation

TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined

Warning : It must be noted that those formula aim at giving an idea of the size of the screw conveyor (which means its diameter) and the speed at which it will operate, based on some assumptions and some design decisions (choice of screw pitch, inclination). The formula can also be used to roughly check the capacity of an existing screw feeder. They are not meant for a detail design and for

All About Screw Conveyors Types, Design, and Uses

16/4/2021· A screw conveyor (also known as an auger conveyor) is, unsurprisingly, the shape of a typical screw, albeit with some caveats. Firstly, the threads are exaggerated and the center may or may not be present (see Figure 1). However, they function almost identically to screws, where a drive motor turns the screw

The starting torqueContrary to the approach of all the formulae present in literature which give the power at operating speed, industrial experience however clearly shows that the most important phenomenon as regards sizing the power is that of starting torque.In fact, the operating torque is usually 60-65% of the nominal torque of the motor in screw conveyors, and even lower in screw feeders
