The main raw materials used in the cement manufacturing process are limestone, clay, sand, shale and iron ore. Limestone is usually mined on site while the other minor materials may be mined either on site or in nearby quarries. Another source of raw materials is industrial by-products. The use of by-product materials to

Raw Material Grinding. Next, a measured quantity of limestone is extracted from our limestone hopper. Additives, such as laterite, iron ore or clay, are also extracted from their respective hoppers and mixed with the crushed limestone. These additives are added to the limestone to enhance the reactivity of the limestone

The principal raw materials for an integrated mill are iron ore, limestone, and coal (or coke). These materials are charged in batches into a blast furnace where the iron compounds in the ore give up excess oxygen and become liquid iron. At intervals of a few hours, the accumulated liquid iron is tapped from the blast furnace
