A major benefit of shaftless screw conveyors is the elimination of intermediate hanger bearings to support the screw sections. Intermediate hanger bearings are a constant maintenance issue and can be a restriction to bulk material flow. Shaftless screw conveyors rely on trough liners to support the shaftless spiral and provide a bearing surface.
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. Engineering Guide Industry Solutions
Table of Contents Download Guide Screws can be configured for every application. The Basic Conveyor Flight and Pitch Type Section provides descriptions of various types of screws that can be used in a multitude of bulk material conveying and processing applications. The use of helicoid or sectional screws is
Shaftless screw conveyors are ideal for pulling vertical conveyors since there is not a bottom shaft or seal. Cons of a shaftless screw conveyor: A Shaftless conveyor is going to need the liner removed and replaced since it is a wear item. This can often be an issue if the screw conveyor is located high up or in a tight location. For longer runs and higher volume applications, there will be the need for reinforcements on the screw, due to the compression of the spiral under pushing load, and ...
