Manufacture of cement. 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.

Cement Manufacturing Process Npc

Raw Material Extraction. Cement uses raw materials that cover calcium iron and aluminum. Such raw materials are limestone shale and sand. Limestone is for calcium. It is combined with much smaller proportions of dolerite sand and aluminium. Sand amp; clay fulfil the need of silicon iron and aluminum. Generally cement plants are fixed where the quarry of limestone is near bye.
