The cement grinding process is the final stage in the production of cement, where clinker particles are ground into a fine powder. This process involves the use of a cement mill, which contains grinding media (balls or cylpebs) that crush and grind the clinker particles. List of cement grinding process:

Pre-grinding to a fineness of 2500- 3000 Blaine is per­ formed in the coarse grinding mill. In the open circuit fine grinding mill, fine particles of up to 6000 Blaine can be attained [143b]. The one-compartment fine grinding mill is filled with 4- 8 mm cylpebs grinding media; because of its small size, the grinding media are called minipebs.

The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%. Role of Gypsum in Cement The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water.

 — In this study, the effect of cement fineness and its grain size distribution on compressive strength and water-reducing admixture demand for providing target flow value was investigated.

ulometric distribution of the clinker in a ball mill operating in dierent rotation speeds, varying the lling degrees of grinding media and clinker. Then, through DEM simula-tions, it was analyzed the dynamic of grinding media and the collision forces engaged between them and between the grinding media and the wall. These results were related to

[2], [7], [6], [11] Almost all Grinding Aids types can accelerate the hydration of the aluminate phases, for that reason a fine tuning is needed to adjust the gypsum additive in mills to control setting time, especially when producing High Blaine Cement.
