CHAIN-AUGER DRIVE

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. Screw conveyors in modern restaurant equipment are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food, ice, waste, wood chips, cereal grains, meat, and many others.

A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension.
