Screw Conveyors


Shafted screw conveyors: Are used in thousands of industrial applications every day for efficiently conveying a variety of bulk materials. A screw conveyor’s main function is to transfer bulk materials from one process to another. Screw conveyors are very cost-effective and require minimal maintenance to operate.

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.

Vertical screw conveyors: Are a very efficient method for elevating a variety of bulk materials at very steep inclines or completely vertical. The compact design allows for the vertical screw conveyor to fit into almost any plant layout. With a minimum number of moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.

Flexible Screw Conveyors: Move virtually any bulk material. Free-flowing and non-free-flowing materials and blends.Flexicon flexible screw conveyors offer efficiency and versatility, conveying bulk materials ranging from large pellets to sub-micron powders—both free-flowing and non-free-flowing—with no separation of blended products.
All Flexicon flexible screw conveyors are available on caster-mounted frames with conveyor support masts for in-plant mobility, reducing the need for multiple stationary units.

Heat Transfer Screw Processors: During the processing of many bulk materials, there is a requirement to cool, heat, or maintain a specific product temperature while conveying the product. The desired temperature fluctuations must be calculated and engineered into the system to accomplish the preferred objectives. KWS Heat Transfer Screw Processors are the perfect solution for these applications.
