KWS designs and manufactures Shaftless Screw Conveyors to meet the needs of many industries, such as chemical, rendering, wood products and wastewater treatment.
KWS Shaftless Screw Conveyors efficiently convey dry, semi-fluid or sticky materials. The shaftless design provides a nonclogging conveying surface by eliminating the need for intermediate shaft bearings.
KWS Shaftless Screw Conveyors provide the flexibility you need for a variety of applications.
KWS Shaftless Screw Conveyors are a wise investment. Lower capital cost and lower overall maintenance are realized from equipment designed to require fewer parts. Better performance is achieved through zero-clearance between the trough and spiral. This improves conveying efficiency and eliminates many of the flow-impeding issues common with shafted screw conveyors. Higher trough loading allows for lower operating speeds. Finally, the KWS Shaftless Screw Conveyor design allows for greater flexibility and efficiency in plant layout, providing for end-to-end, side inlet/discharge and vertical configurations.
Every KWS conveyor system is manufactured in the USA by highly skilled craftsmen who show their dedication to producing quality products every day.
