Screw Conveyors

screw conveyors is 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. 
manufacturers use screw conveyors to transport materials such as flakes, grains, powders, seeds and granules. Alternatively, these devices can be used to mix, agitate or blend such materials, or to maintain solutions. They are used widely in agricultural applications, from use in farm machinery like threshers and balers to factory-based grain and crop movers. Screw conveyors are also an excellent solution to operations requiring the transport of wet, non-flowing and caking materials that might otherwise be difficult to move.
