The Cement Manufacturing Process - CMA India
After receiving cement raw materials from the Indian mining industry, limestone is transferred in raw mill for grinding into a fine powder. This fine powder of limestone is then heated at a very high temperature of 1450 degrees centigrade for clinkerisation. To heat, this fine powder at such high-temperature coal is used in clinkerisation section.
