Screw Conveyor an overview | ScienceDirect Topics

Screw Conveyors. A screw conveyor or auger system is composed of several parts. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting. The distance along the pipe from one point on the flighting to the next similar point is called the “pitch”.
