thyssenkrupp Industrial Solutions - Cement Manufacturing. In the final process stage of cement manufacturing, the cement clinker is extracted from the clinker stores or silos and finely ground, together with gypsum as a setting regulator and possibly other additive materials with hydraulic or pozzolanic properties.
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 limestone in the clinker production process.. From 2014 to 2018, the clinker-to-cement ratio increased at an average of 1.6% per year, reaching an estimated 0.70 in 2018; .
Competence for the processes in the Cement Industry 6 The Cement Industry typically produces Portland cement – sometimes also masonry cement.
