The Cement Manufacturing Process. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.

Cement production is an energy intensive industrial process that requires heat to be supplied at high temperature levels under the constraints of gas-solid heat exchange phenomena and the kinetics of chemical reactions.
