Heat Transfer Screw Conveying

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 Conveyors are the perfect solution for these applications


  • Common Applications
  • Cooling fly ash from boilers at coal-fired power plants
  • Heating lime for asphalt shingle operations
  • Maintaining a specific temperature for food products
  • Cooling drill cuttings from a rotary dryer

Our heating and cooling screw conveyors indirectly transfer heat to or from the product by introducing a heat transfer medium such as cool water, hot oil or steam through a special trough jacket and/or the pipe and hollow flights of the screw conveyor. Achieving the specified exit temperature of the product is accomplished by calculating the surface area of the auger and designing the system flow to match the heat load requirements of the application.

A properly designed system will be very cost-effective when compared to other heating and cooling screw conveyors. KWS designs and manufactures heating and cooling auger conveyors to meet the needs of many industries, such as Chemical, Minerals Processing, Food, Power and Wastewater Treatment.
