Thermal processing of powders, granules and bulk products in continuous, electrically heated process and controlled atmospheres. Since 30 years, we produce precise, high quality equipment for a climate friendly industry. Our solutions are alternatives to the old, fossil-fuel based processes in minerals, food and chemical industries. Technology concept based on electricity supports the global energy transition.
SPIRAJOULE: Equipment for CONTINUOUS HEATING OF ORGANICS AND MINERALS
Spirajoule is eletrically heated screw conveyor proven for 20 years in industrial operation. Technology allows perfectly controllable, thermal processing of organics and minerals. Our system is dedicated for a continuous thermal treatment in temperatures up to 850 degree C, basing on a hollow shaft screw conveyor heated by a low voltage current. The screw is made from electrically conductive material and is connected to an electricity power supply.
Electricity is conveyed from the power supply by the specially design components located at both sides of the screw. The passage of electronic current through the conductor (screw) generates heat, which is as a result of Joule heating (also known as Ohmic heating or resistive heating).Â
