SHAFTLESS SCREW CONVEYORS
Our screw conveyors of the shaftless type are designed to handle greater flow rates and are suitable for transporting heterogeneous or tangled materials that tend to cause machine blockages. This particular machine is designed to convey screenings, sands, granular substances and sludge.
The material is transported by a thick shaftless spiral that slides along an anti-friction and anti-wear coating at the bottom of a trough.
Contact us if you are interested in a shaftless screw for conveying screenings, sludge, sand, and much more. We can provide both standard and custom-built equipment to suit your needs.
The machine may have a pull or a push configuration:
- “pull”: the gear motor located downstream of the discharge outlet drags the material towards the outlet.
- “push”: the material is pushed by the screw spiral towards the outlet.
The system can be activated by connecting the gear motor directly to the spiral, or via a gear motor – chain flanged shaft spiral transmission system.
The working range of the conveyor is typically between 0° and 30°; machine performance decreases as the inclination increases. Contact us to inquire about our products!
