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.
