Screw Conveyor definition of Screw Conveyor in the Free Online Encyclopedia.

screw conveyor [′skrü kən′vā·ər]

(mechanical engineering)

A conveyor consisting of a helical screw that rotates upon a single shaft within a stationary trough or casing, and which can move bulk material along a horizontal, inclined, or vertical plane. Also known as auger conveyor; spiral conveyor; worm conveyor.

Screw Conveyor

a mechanism whose working member is a shaft with a continuous helical blade (the screw) or individual, pitched vanes. The rotating shaft, housed in a horizontal or inclined trough, moves loose or small piece cargoes or liquids along the trough. Screw conveyors are used in extruders, feeders, and other machines. They offer design simplicity and even feeding, but they have low productivity and efficiency because of the friction of the material against the walls. Feeding is regulated by the frequency of rotation of the screw. A screw conveyor was used in Archimedes’ screw, a device designed to raise water. Screw conveyors in which the screws of two adjacent machines rotate in opposite directions are used to mix materials.
