How cement is manufactured

Cement manufacturing is the basic processing of selected and prepared mineral raw materials to produce the synthetic mineral mixture (clinker) that can be ground to a powder having the specific chemical composition and physical properties of cement. Some typical materials used for calcium carbonate in cement manufacturing are limestone, chalks, marbles, marls, and oyster shell. Some typical materials used for alumina in the cement manufacturing are shale, clay, slags, fly ash, bauxite, alumina process waste, and granite. Some typical materials used for silica in cement manufacturing are sand, clay, claystone, shale, slag, and fly ash. Some typical materials used for iron in cement manufacturing are iron ores, blast furnace flue dusts, pyrite clinker, mill scale, and fly ash.

Cement plants are typically located central to the minerals required to make the cement, which saves the transportation costs and reduces the price of the cement. Once the ore material to be used for cement has been mined, it is transported to the crushing/screening plant, where it is crushed and screened, to produce the desired particle size. Ore from the mines are typically reduced to about ¾ inch and stored in a coarse stockpile. From there, the ¾ inch ore is typically reduced to a powder in a large ball mill.

Liming Heavy Industry manufactures different kinds of crushing and grinding equipments, which are widely used in cement production line. If you want to manufacture cement, we can help you work out the best cement production line and select the most suitable cement manufacturing equipment.
