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.

BASIC CONCEPTS OF PRIMARY SIZE REDUCTION. In a cement plant, crushing is the primary size-reduction process carried out under the action of external mechanical forces. Generally, three levels of crushing are recognized: coarse (top product size, up to 150 to 200 mm), intermediate (up to 40 to 70 mm), and fine (up to 5 to 25 mm).
