Cement is produced by heating the raw materials toproduce slaked lime (CaO) and other compounds in the chemical process of calcination. Large roller kilns, operating at 1450–1500°C, fire the input slurry to produce marble-sized cement clinker, which is then crushed to yield the final fine-powder product.
Themaking processof portlandcementin the modern industry can be divided into the wetprocess, dryprocess, and semi-dryprocess. Nowadays, the dryprocessis the most popularcement making processwhich is widely adopted bycement plantsall over the world for its great advantages in energy saving and environmental protection.
Cement is typically made fromlimestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
Aug 20, 2015· Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, calledraw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
The last stage ofmaking cementis the final grindingprocess. In thecement plant, there are rotating drums fitted with steel balls. Clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it contains 150 billion grains. This powder is the final product,cement…
