Screw Conveyors

Screw Conveyors

Screw conveyors are one of the oldest methods for conveying bulk materials. A rotating screw is housed inside of a sealed trough. The screw flights propel material as the screw turns. Modern screw conveyors are simple and efficient, can handle materials with a wide range of properties, and can be applied in incline or decline situations as well as in areas where space is limited. Screw conveyors are rotated with electric motors and gear reducers. The motors can be direct coupled to the reducer, or can be connected with v-belts and sheaves or chains and sprockets.

Screw conveyors are utilized for transporting material in horizontal or incline positions, to meter and control material flow or to vertically convey materials when space requirements are limited. A screw conveyor consists of a helical screw that rotates upon a single shaft within a stationary trough or casing, which moves bulk material along a horizontal, inclined, or vertical plane. Other names for screw conveyors include auger conveyor; spiral conveyor and  worm conveyor. Screw conveyors are available in standard sizes from 4" through 24" diameter, as well as larger made-to-order sizes up to 120" diameter.

Screw conveyors are utilized in numerous bulk handling operations.

Notable industries utilizing screw conveyors include: waste water, pulp and paper and steel fabrication.
