Applications

KINTEK's Electric Rotary Kilns are widely used across various industries for diverse thermal treatment processes, including but not limited to:

  • Calcination and drying of positive and negative electrode materials for batteries
  • Processing of rare earth materials
  • Production and regeneration of chemical catalytic materials

Principle of Operation

The KINTEK Electric Rotary Kiln operates by continuously feeding material into a rotating cylindrical chamber (tube). This tube is externally heated by high-performance electric heating elements, segmented into multiple zones for precise temperature profiling. As the material tumbles and transits through the heated chamber, it undergoes the desired thermal process, such as calcination, drying, or pyrolysis. The rotation and tilt of the tube ensure uniform heating and controlled movement of the material towards the discharge end. The system can be operated under ambient or controlled atmospheres (e.g., inert gas) to prevent oxidation or achieve specific reaction conditions.
