According to the cross section of the silo outlet, SU-type Single Shaft Screw Feeders are available with standard U-shaped or with flared V-section trough. In a light-duty version, SU-Feeders are used for flour and materials with similar bulk density and properties. For animal feed and similar products a heavy-duty version is available.

SU Screw Feeders are available with ATEX, Zone 22 certification.

Function

Some powders or granular materials are so poorly flowing that they cannot be stored in silos with a circular outlet cone. The silo simply would not empty. Such materials (e.g. flour) require storage in silos with a steeper cone and an oblong outlet opening. With their inlet trough section SU-type Screw Feeders match the shape of the silo outlet. The trough section is coupled to a tubular section for efficient material feeding towards further processing.
