The Principle of Screw Conveyor

Screw conveyor is divided into shaft screw conveyor and screwless screw conveyor according to the form of transport, according to the exterior, divided into U-type screw conveyor and pipe-type screw conveyor. Shaft screw conveyor is suitable for non-sticky dry powder materials and small particles of material. Shaftless screw conveyors are suitable for conveyors made of viscous and easily wound materials.

About the screw conveyor works, rotating spiral vane delivery the material to screw conveyor, friction resistance between the weight of the material and the screw conveyor housing make the material rotate with the screw conveyor blades.
