The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers which transport the materials and unload into hoppers

Cement Manufacturing Process. The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to 80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw materials in the

Energy costs and environmental standards have encouraged cement manufacturers worldwide to evaluate to what extent conventional fuels can be replaced by different alternative fuels, processed waste materials. The clinker burning process is well suited for the use of various alternative fuels because of the long residence times in both rotary kiln and gas channels.

In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw meal. The raw meal is pumped into a blending silo.
