Cement Raw Material Grinding Process

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 Phases 1. 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 clay fulfil the need of silicon, iron and aluminum.The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
