Shaftless Screw Conveyor Calculations | …
Demand horsepower of the shaftless screw conveyor is calculated in two parts. First, the horsepower to turn the conveyor empty, or the Friction Horsepower is calculated. Then, the horsepower required to move the material, or the Material Horsepower is calculated. Empirical factors like Fd and Fb have been developed by KWS through years of experience and testing of bulk materials. These factors help account for conveyor …
Screw Conveyor Engineering Guide - Horsepower …
Total Shaft Horsepower (TSHP) is calculated by adding Material Horsepower, multiplied by the appropriate modified flight factor or factors, to Friction Horsepower. Note: Conveyors which have deviation in pitch only do not require special consideration, and their horsepower calculations are as described for standard conveyors.

The horsepower required for operating screw conveyors depends on proper machine installation and regular conveyor feed rate. The total horsepower capacity of a screw conveyor system is calculated using 4 important factors. The horsepower required to overcome friction (HPf) The horsepower required to transport material at a specified rate (HPm)
Finding the Best Screw Conveyor Horsepower - JMS
Once it has been determined that a Screw Conveyor will best fit your application, and the type of screw conveyor you will use (shafted or shaftless), a calculation will be completed to specify the horsepower that will be needed to meet the needs of the application. Simply put, horsepower is a measure of the rate at which work is done.
