Clinkerization - Cement Plant Optimization

Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.

How Cement And Concrete are Made | Rediscover Concrete

This results in the production of cement clinker, an intermediate product in the manufacture of cement. The cement clinker emerges from the kiln, is cooled, and then finely ground to produce the powder we know as cement. The fuels combusted to heat the kiln account for about 40% of cement manufacturing emissions.

In cement plants, industrial ecology can be reflected in two ways: - partial substitution of traditional fossil fuels with alternative fuels - use of cement additives as raw materials as a partial substitute for clinker. This may involve by-products such as slag from the steel industry or fly-ash from coal-fired power stations.
