Rotating Screw Discharger type RAS

In use for alternative fuels and biomass

The Rotating Screw Discharger type RAS is a discharge system for dry or damp bulk materials which do not flow easily. The Screw Discharger travels over the silo floor by rotating around the vertical axis of the cone, and conveys the material into the chute beneath the cone.

The Screw Discharger can be adapted to the individual bulk material by variations in the design of features such as the cladding, the teeth, or the pitch of the screw. Screw Dischargers can be installed in steel or concrete silos. Depending on the material properties and the diameter of the silo, conveying capacities of up to 450 m³/h can be achieved. The maximum silo diameter is currently around 25 metres.
