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 cement .

Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

Cement Manufacturing Process Stepbystep Guide Cce L. Jul 20, Cement manufacturing process in summary. Portland cement is manufactured by heating limestone calcium carbonate with other materials such as clay to 1,450 176C 2,640 176F in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime.

· Cement Cement Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
