An auger conveyor (or screw conveyor) is a mechanical device that uses a rotating helical screw blade—called a "flighting"—inside a tube or open trough to move bulk materials from one point to another. 

How It Works

• Rotation: A drive motor turns a central shaft or flexible spiral coil.

• Movement: As the screw turns, material fed into the inlet is pushed forward along the axis of the screw by the friction of the rotating flights.

• Orientation: These systems can transport materials horizontally, at an incline, or completely vertically.
