Screw conveyors, or auger conveyors, are industrial equipment used in transporting bulk quantities of granular solids (e.g., powder, grains, granules), semi-solids, liquids, and even non-flowing materials from one point to another. They uphold high operational efficiency by eliminating the need for the workers to manually move around loads.

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. Couplings and shafts refer to the mechanisms by which two screw conveyors are joined.
