Clinkerization - an overview | ScienceDirect Topics

This clinker is then ground in the ball mill together with gypsum and other additives to reduce cement. The main energy-intensive phase of the cement production process is the precalciner, kiln, and during the production of clinker. A large amount of thermal energy is required to create enough heat for the cement kiln and precalciner.

Manufacturing Process – Continental Cement

The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
