Today's portland cement still relies on Aspdin's raw materials for its basic components ofcalcium,silica,alumina, and iron. The most common combination is limestone, clay, and sand. In today's cement production, minerals from a quarry near the plant are ground to fine powder, then blended to the exact proportions needed for the final cement product.Get Price

Cement plantsare typically located central to the minerals required to make thecement, which saves the transportation costs and reduces the price of thecement. Once the ore material to be used forcementhas been mined, it is transported to the crushing/screeningplant, where it is crushed and screened, to produce the desired particle size.Get Price
ALTERNATIVE RAW MATERIAL SOURCES FORCEMENTPRODUCTION.Cementis a complete mixture of mineral substances that gradually harden when mixed with water. It is the product of the reaction of lime with the oxides of silica alumina and iron. It is used in the construction of industry as a blending material.Get Price
