Vertical Screw Conveyors

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.

  • Ability to elevate bulk materials up to 30-feet without use of internal bearings
  • Totally enclosed design for dust and vapor-tight requirements
Vertical Screw Conveyor Benefits

KWS designs and supplies 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.
