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.

The raw materials mix composition would be 90-93% limestone, 2- 3% clay, 2-3% Bauxite, 1-2% Iron ore in cement making. Fuel: Coal is used for burning the raw mix in powdered form. Normally both imported and indigenous coal are used, coal is being imported from mainly South Africa, Australia etc. because of low ash content.

A cement mill is a grinding machine that used to grind hard, nodular clinker from cement kiln into fine powder that is cement. At present, most cement is ground in ball mills. As the rapid development of construction, more and more cement are required. Grinding systems are either 'open circuit' or 'closed circuit.'.
