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.

Grinding and homogenization. The grinding process takes place in a raw mill to reduce the particle size of the components to a typical value of 10-15 % residue on a 90 um sieve. The output of the grinding process – called 'raw meal' – is transferred to a homogenization silo before the clinker manufacturing process.
