Trough screw conveyors
Trough screw conveyors move bulk materials horizontally or on a slight upward incline
Trough screw conveyors made by PAUL GROTH can transport floury, grainy and lumpy bulk materials. In the appropriate version, trough screw conveyors can also be used for dosing, wetting, mixing or crushing.
Trough screw conbveyor for food are easy to clean. Every surfaces inside and outside are easily accessible. All materials and substances in contact with product are food compatible.
Starting with our standard modular-system we adapt the trough screw conveyor to the product properties, the installation option and the process requirements.
