Tubular Screw Conveyor

The tubular screw conveyor is a closed spiral conveyor designed specifically for transporting materials within a tube. It consists of a closed pipe and a drive mechanism, with spiral blades installed inside the pipe. As materials are fed in from one end, the rotating action of the spiral blades pushes them along the inner wall of the tube to the other end. This design features a compact structure and excellent sealing, making it ideal for transporting materials that require high hygiene standards, particularly in the food and pharmaceutical industries.
