Vertical Screw Conveyor Engineering Guide

Vertical Screw Conveyor Illustration

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

KWS designs vertical screw conveyors to meet the needs of many industries, such as Chemical, Minerals Processing, Food, Wood Products and Wastewater Treatment. For example, our unique shaftless vertical screw conveyor design is used in many Wastewater treatment facilities for elevating dewatered biosolids.

KWS Vertical Screw Conveyors are available in many configurations. Inlet sections can be offset to either side or can be in-line. Horizontal feed conveyors are required to accurately meter bulk materials directly to the vertical conveyor’s inlet for maximum efficiency.
