In the manufacture of OPC cement, heating is the main important step. In this step, with the help of conveyor belts, the product obtained from the mixing is passed into the Kiln. Firstly, to 550C the mix is preheated and all the moisture content is evaporated and clay is broken into silica, iron oxide, and aluminum oxide.
