Screw Conveyor Manufacturers Screw Conveyor Suppliers

Screw Conveyors. Screw conveyors, also known as auger conveyors or industrial screw conveyors, are systems designed to transfer free-flowing and non-free-flowing, dry and semi-dry bulk materials.Note: Since the operation of the system involves a screw cutting through the bulk materials, we do not recommend using screw conveyors to process substances that are sticky or do not break down
