Calcination is a thermal treatment used to cause chemical separation. It refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.

Rotary kilns are generally used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired or indirect-fired type. Here in Kani Sanat, we design and manufacture custom rotary kilns based on the needs of customers’ process and material.
