Clinker is the main ingredient in cement and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing due to both the combustion of fuels and the decomposition of the limestone in the processClinker is produced by sintering limestone calcium carbonate and clay alumino silicate at elevated temperatur 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
More InfoConsistently creating the perfect clinker recipe Clinker manufacturing is an energy intensive activity and choosing fuels the right blend of hot gases and optimum burner control affects both the environmental impact and the economics of the processFrom the limestone quarry to the delivery of the end product follow every step in the cement manufacturing process Step 1 extraction of raw materials The raw materials needed to produce cement calcium carbonate silica alumina and iron ore are generally extracted from limestone rock chalk clayey schist or clay
