Auger Conveyor
An auger conveyor, also known as a screw conveyor, moves solid or liquid material by moving it on the threads of the auger. The auger is usually located in either a trough or tube and is oriented at a slight incline or vertically. As the auger rotates, material clings to the augur surface and is transported up the shaft. The pitch of the auger - the linear distance is takes to complete one complete revolution around the shaft - determines how slowly or quickly the material progresses from one end to the next at a given shaft speed.
