Rotary Kilns by Therelek

The material is processed in the rotating drum at high temperature for a precise time to induce a physical change and is kept inclined to assist the moving material inside.

In direct-fired kilns, the material is directly in contact with the process gas. Indirect fired kilns are used for applications where the processing occurs in an inert atmosphere or when the material has to be controlled.
Ā 
It is refractory lined because of the high amount of heat is being pushed inside. External heating is applied to kiln enclosed in the furnace thus by avoiding contact with combustion gas and material.
Ā 
This is a highly resourceful thermal processing machine capable of treating a variety of components for an application like calcination, thermal desorption, organic combustion, sintering.

Why Choose Therelek?

  • Therelek Engineers designs and manufactures rotary calciners to the requirement of the end-user.
  • Rotary calciners are directly or indirectly heated by gas-fired burners, the rotating element is a metallic tube.
  • The orientation of the burner (or burners) depends on the application and functional requirement and can either be located at the entrance of the calciner or perpendicular to the calciner rotation.
  • The rotating metallic tube and rotation speeds are determined by the composition of the feed and output required, and the material selection is based once again on the composition and operating parameters like temperature and gases formed during the process.
  • Suitable cooling arrangements are made to ensure the feed comes out of the rotary calciner at the acceptable temperature range without risk of oxidation.
