Screw conveyors

Haarup supply screw conveyors for cement, fly ash and silica.

The conveyors are equipped with adjustable ball joints for installation below the cement silo and the required number of sturdy suspension brackets.

Each conveyor has a robust geared motor, and Haarup generally use gears and motors that are one size larger than normal for the industry.  

The conveyors have progressive windings below the inlet to ensure that the powdered materials are not compacted in the windings.

In the standard version, the conveyors have an inspection gate below the inlet.
