The cyclone preheating system Phase IV: Calcination. The calcination is the core phase of the cement making dry process. The calcination of the preheated raw meal takes place in the rotary kiln of the cement plant. The rotary kiln is a huge rotating furnace in which the raw meal is heated up to 1450 ⁰C and turned to clinker.

What makes concrete so strong is the chemical reaction that occurs when cement and water mix — a process known as hydration. "Hydration occurs when cement and water react," says Ulm. "During hydration, the clinker dissolves into the calcium and recombines with water and silica to form calcium silica hydrates."

However, when the road to carbon neutrality is the topic, then the clinker capacities and clinker utilisation rates become more important, because the clinker process is responsible for about 2/3 of the direct CO 2 emissions of the cement industry. With a clinker factor of 74% in 2021 (Cembureau) the EU27 clinker production was about 146.2 Mt/a.
