Clinker Making Industrial Efficiency Technology Measures

Clinker is produced by sintering limestone (calcium carbonate) and clay (alumino-silicate) at elevated temperatures. The production of clinker involves the feeding of the raw meal into the kiln, where first the calcination of calcium carbonate takes place and then the resulting calcium oxide is burned at high temperatures together with silica, alumina and ferrous oxide to form clinker.
