The main source of heat is coal burning. Coal is fired as a main fuel () in the rotary kiln and calciner chamber. Coal is burnt to provide the required heat for calcination and to convert the kiln feed into clinker. This red hot clinker further goes to clinker cooler for cooling the clinker from 1400 degrees to 200 degrees.
