Shaftless Screw Conveyors

Bulk materials discharged from centrifuges, filter presses or mixers can easily be metered or conveyed using a shaftless screw conveyor. Our shaftless design provides a non-clogging conveying surface that allows difficult-to-convey materials to become easy-to-convey. The perfect solution for handling bulk materials with high moisture content is the KWS Shaftless Screw Conveyor.

KWS Shaftless Screw Conveyors are successfully used throughout the chemical, food, minerals processing and wastewater treatment industries for conveying everything from catalysts to dewatered biosolids.

KWS developed the industry standards for shaftless screw conveyors and continues to create new and improved design standards. Our high strength alloy spirals are the hardest, strongest and toughest in the industry.
