They function almost identically to screws, where a drive motor turns the screw (also known as the auger), moving product up one pitch every revolution. The auger is typically in coupled sections and is supported by bearings on either end, where coupling bolts transmit the motor torque to power the conveyor. A tube or U shaped trough around the auger acts as the conveying surface, where powder bulk, granular, and even non-flowing material is pushed along the trough surface. The function is to push material as the screw rotates in a fixed trough, pipe or housing. Using rotating helical screw blades ( also referred to as flights or augers), To move liquid or granular materials. They are used in many bulk handling industries. The materials that are abrasive and coarse can also lead to the wear and tear of the screw.
