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 ...
