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 inert atmosphere or when the material has to be controlled.

It is refractory lined because of 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

This is a highly resourceful thermal processing machine capable of treating variety of components for application like calcination, thermal desorption, organic combustion, sintering.
