Screw Conveyor - an overview | ScienceDirect Topics

9.15.1 Screw Conveyors. Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. 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.
