Shaftless Screw Conveyor
Shaftless Screw Conveyor
The Shaftless Screw Conveyor is designed to move sludge and other difficult materials in wastewater systems. Its shaftless spiral design helps prevent clogging and allows smooth handling of sticky, fibrous, or uneven solids. Its enclosed structure keeps the process clean, reducing spills and odours. With no internal bearings, it needs very little maintenance and has a long service life. It can be installed at different angles to fit various layouts. Made from durable stainless steel, it offers reliable, efficient, and low-maintenance performance for both industrial and municipal use.

Features
Standard Features
- Shaftless spiral design to eliminate clogging and improve conveying efficiency
- U-shaped trough construction for stable and controlled material transport
- Fully enclosed system to reduce odour and environmental contamination
- No internal bearings, reducing wear and maintenance requirements
- Flexible spiral suitable for handling sticky and fibrous materials
- Stainless steel construction (SS304) for durability and corrosion resistance
Options & Accessories
- Customised conveying length and installation angle
- Inclined or horizontal installation configurations
- Material upgrade options for specific operating conditions
- Additional covers or sealing systems for enhanced containment
Working Principle
The Shaftless Screw Conveyor consists of a shaftless spiral rotating inside a U-shaped trough, equipped with an inlet hopper and discharge outlet. As the spiral rotates, material moves along the trough towards the discharge point. The shaftless design allows materials to be conveyed without obstruction, particularly for sticky or entangled solids. The enclosed structure ensures clean and controlled transport while reducing wear and maintaining efficient operation over time.
Key Benefits
- Non-Clogging Operation
The absence of a central shaft significantly reduces material blockage and entanglement, ensuring continuous and reliable conveying performance. - High Conveying Efficiency
The flexible spiral design allows effective handling of sticky, fibrous, and irregular materials that are difficult to transport with conventional screw conveyors. - Low Maintenance Requirements
With no internal bearings and a simplified mechanical structure, maintenance needs are minimised, and service life is extended. - Fully Enclosed & Hygienic Design
The enclosed trough construction prevents material spillage, reduces odours, and improves environmental conditions. - Flexible Installation
Capable of operating at various inclinations, the system can be adapted to suit different plant layouts and installation requirements.
