Calcination Process Development & Calcining Equipment

Rotary kilns are 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. It is also common to follow the calcination process with a rotary cooler. This efficiently cools the material after it has been calcined, so it can move on to,Rotary Kiln Maintenance Procedures,rotary kiln operations. Regardless of rotary kiln size or configuration the basic principles outlined in this manual govern the reliable operation of every rotary kiln, calciner, dryer, incinerator, digester and cooler application.
