Shaftless Screw Conveyors are successfully used throughout the chemical, food, minerals processing and wastewater treatment industries for conveying everything from catalysts to dewatered biosolids. The highly efficient Shaftless Screw Conveyors achieve its top of the line performance through zero-clearance between the trough and spiral, improving conveying efficiency and eliminating many of the flow-impeding issues common with shafted screw conveyors. Higher trough loading allows for lower operating speeds. The special  design  requires less parts, resulting in lower capital cost and lower overall maintenance costs. KWS Shaftless Screw Conveyors are designed for greater flexibility and efficiency in plant layout, providing for end-to-end, side inlet/discharge and vertical configurations.
