Design possibilities

Screw conveyors can be divided into two main types: Transport and discharge screws. Transport screws is used for transporting materials from one point to another, and are characterized by low fill rate and relatively high speed. The Discharge screw is used for consistent and accurate feeding of materials for example  outputs from silo/bins. Unlike the Transport screw, the Discharge screw always operates with filled through.
