Tubular screw conveyors

Tubular screw conveyors for horizontal and upward transport

Tubular screw conveyors from PAUL GROTH can transport floury, grainy and lumpy bulk materials.  Like our trough screw conveyors, tubular screw conveyors can also perform other tasks such as dosing, wetting, mixing and crushing.

Starting with our standard modular-system we adapt the tubular screw conveyor to the product properties, the installation option and the process requirements.
