Screw Conveyor

A screw conveyor, also known as an auger conveyor, is a mechanism that uses a rotating helical screw blade, called an auger, within a tube or trough to move bulk materials. The basic working principle of a screw conveyor is that the rotation of the helical screw blade pushes the material along the trough or tube. The screw rotates inside a stationary casing, and as it turns, the material is carried forward in a continuous flow, similar to how a corkscrew moves a cork out of a bottle.
