Cement Extraction and processing Britannica. There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as clinker, together with some 5 percent of gypsum (to control the time of set of the cement) The
Raw material proportioning The homogenized limestone and clay/silcastone along with other raw materials like sand and iron ore are reclaimed into separate feed bins. The proportional ratio of the raw materials is fixed using raw mix design and is determined from the chemical analysis of the raw materials.

Cement Raw Materials used in Manufacturing of Cement
Raw Material Preparation Cement Plants and Kilns in From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below mm), followed by a tube mill for fine grinding.
#0183;#32;Raw materials used for manufacturing of Portland cement are found naturally in the earths crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silicaalumina and iron. Both are found as clay or shale.
