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.

1. What is a shaftless screw conveyor?
A shaftless screw conveyor is a material handling system that moves sludge and solids using a rotating spiral without a central shaft, reducing the risk of clogging.
2. What are the main advantages of this system?
It works without clogging, runs efficiently, and doesn’t need much maintenance. The closed design helps keep bad smells in and prevents any material from spilling.
3. Where can a shaftless screw conveyor be used?
It is commonly used in wastewater treatment plants, sludge handling systems, food processing, and industrial facilities to transport sludge, screenings, and other difficult materials.
4. Can the conveyor be installed in different layouts?
Yes, it can be installed horizontally or at an incline, and the length and configuration can be customised to suit different plant layouts.

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.
