process of cement production

Cement Production

The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder It is then preheated to save energy before being transferred to the kiln, the heart of the process The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.

Cement kiln

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicatOver a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
