U-Type Screw Conveyor

U-Type screw conveyors

The name of the conveyors comes from the shape in which the screw coil is located. The shape is like a trough or similar to the shape of the letter U. Trough augers are widely used in industries because of their strongest feature – namely the ability to transport wet and sticky materials without blocking the system.
