SikaGrind® for vertical roller mills
The common intergrinding of limestone and clinker in classical ball mills is there-fore producing a cement of very high surface. The higher the limestone content, the higher the negative impact of its surface on water demand and powder flowability. The intergrinding of Portland-Limestone Cement (PLC) with Vertical Roller Mills avoids

Clinker size and cement grinding | GCP Applied Technologies
As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

The effect of ball size on mill performance
The ball motion in the mill was simulated via discrete element method (DEM). Our results show that steel balls achieved faster breakage of clinker into finer particles than alumina balls, which was explained by the higher total–mean energy dissipation rates of the steel balls. The PSD became finer as smaller balls were used.
