Ultimate Containment and Pressure Resilience
The Tubular Shaftless Screw Conveyor is specifically designed for materials that must be isolated from the environment. The cylindrical pipe structure provides superior torsional rigidity compared to open troughs, allowing the machine to handle higher filling rates and moderate pressure levels without the risk of material leakage or dust emission.
Technical Specifications
- Housing Type: Fully enclosed tubular pipe.
- Material Suitability: Sludge, paste, fibrous waste, and high-odor organics.
- Sealing Advantage: Zero-leakage design with industrial-grade flange connections.

Anti-Clogging Performance
Without a central shaft, this conveyor is inherently resistant to clogging from fibrous or tangled materials. The tubular casing ensures that even pressurized material flow remains consistent, making it highly effective for vertical or steeply inclined transport of dewatered sludge.
Industrial Applications
Essential for municipal sludge handling, pulp and paper processing, and industrial hazardous waste containment.
The tubular shaftless screw conveyor can convey materials that are not easy to be transported by traditional screw conveyor and belt conveyor, such as wet and paste materials, semi-fluid and viscous materials, materials that are easy to be wound and blocked, and materials with special sanitary requirements.
FAQ
Q: Why choose a tubular housing over a U-trough for shaftless conveyors?
A: The tubular design offers 360-degree sealing, which is critical for containing high-odor materials (like raw sludge) or preventing dust leakage in pressurized systems. It also provides higher structural rigidity for vertical or high-incline applications.
Q: Can this model handle highly liquid materials?
A: Yes. With precision-engineered flange gaskets and a fully enclosed pipe, it is specifically designed to transport semi-fluid pastes and dripping sludges without leakage.
Q: How do you prevent the shaftless spiral from wearing through the pipe?
A: We install high-density wear liners inside the tube. These liners act as a sacrificial barrier, allowing the spiral to glide smoothly while protecting the main carbon or stainless steel housing.
