how to mixing of clinker and gypsum:

What is the purpose of adding gypsum in cement?

Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the “setting of cement”.

Difference between Clinker and Cement - Civil Engineering

Clinker is a granular substance containing spherical pellets of diameter 3-25 mm. Cement is such a fine powdery substance that each pound of cement contains 150 billion grains. 3: Clinker is produced inside the kiln during the cement manufacturing process. Raw mix is heated and then rapidly cooled to produce the marble-sized pellets of clinker.

Chemicl parameters defining clinker composition

In practice, the mixing of raw materials is never perfect and there are always regions within the clinker where the LSF is locally a little above, or a little below, the target for the clinker as a whole. This means that there is almost always some residual free lime, even where the LSF is considerably below 1.0.
