Cement Production - an overview | ScienceDirect Topics

The reaction products leave the kiln as a nodular material called clinker. The clinker is cooled in the clinker coolers before being stored in the clinker silos. The clinker is ground with gypsum and other materials such as fly ash in a cement mill to form Portland cement. In this paper, we present two cement related industrial MPC applications.
