Designing Inclined Screw Conveyors for Industrial Applications
Certain parameters are required for sizing a screw conveyor. The capacity calculation for screw conveyors takes into account the outside diameter of the screw, the outside diameter of the center pipe, the pitch of the screw, and the trough loading. The calculation determines the capacity that will be conveyed with each revolution of screw rotation.

Screw Conveyor Horsepower | Engineering Guide - KWS Manufacturing
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 with sufficient horsepower in order to prevent downtime and loss of production.
