In industries such as wastewater treatment, solid waste disposal, and food processing, large quantities of materials are highly sticky, easily entangled, fibrous, or otherwise “difficult to handle”. Traditional shafted screw conveyors often suffer from material wrapping around the centre shaft, leading to blockages and downtime. The shaftless screw conveyor has completely solved this industry pain point.
Core advantages of the shaftless screw conveyor:
Eliminates blockages entirely: The shaftless design removes the root cause of material entanglement, smoothly conveying fibrous, sticky, and high-solid-content materials.
Large-volume conveying capacity: The shaftless spiral provides a larger effective conveying volume, handling materials with wide particle-size variation and complex compositions.
Low-maintenance design: No intermediate hanger bearings are needed, significantly reducing maintenance requirements and wear-part replacement frequency.
Excellent environmental performance: The trough with sealed cover and gaskets enables odour free operation and prevents foreign matter from entering the system.
Flexible configurations: Available in horizontal, inclined, and vertical designs to suit different space layouts.
The shaftless screw conveyor is particularly suitable for: municipal solid waste, screenings and floating debris, dewatered/thickened/conditioned sludge, packaged food and pastes, and meat/fish/fruit and vegetable processing waste. In wastewater treatment, the WLS-type shaftless screw conveyor has become the standard equipment for conveying screen screenings and dewatered sludge cake.
