Manufacturing Process – Continental Cement

This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O.

Ball Mills - an overview | ScienceDirect Topics

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.

As the chemistry of this dust is normally different from kiln feed composition, therefore kiln feed must be adjusted/biased to yield the desired clinker composition. Major portion of this dust is taken to raw mill and coal mill with hot gases and a part of it is directly precipitated in bag filter or electrostatic precipitator before flue gases ...
