Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay to a fine powder called raw meal which is then heated to a sintering temperature as high as 1450 °C in a cement kilnCement manufacturing process & what is cement made of,

there is a marked drop in the efficiency of the grinding when a certain particle size is 65 attained negative pressure suction diethanol amine and water and so on. Therefore coal ganguesManufacturing Cement Grinding. The clinker is combined with small quantity of gypsum and then it is finely ground in a separate mill to get the final product. The mill is a large revolving cylinder containing steel balls that is driven by a motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.Cement is the substance which holds concrete together,
