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.
Brief description of tubular screw conveyors
- Motor bracket with geared motor and flexible coupling
- Tubular screw conveyors made of steel: outside painted and inside untreated, or hot-dip galvanised
- Tubular screw conveyors made of stainless steel: bath pickled or with hand-pickled weld seams, outside glass-bead blasted on request
- Screw thread made of highly wear-resistant steel too
