Breakthrough in Clinker Grinding
Raw materials crushing and grinding seeks to reduce materials from roughly one meter cubes of blasted stone to a size where at least 80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns.

Laying the foundation for zero-carbon cement
Adding CO 2 makes the concrete stronger and reduces the amount of cement needed. Carbon-cured concrete could also use CO 2 captured during cement production. Today's methods could sequester up to 5 percent of the CO 2 produced during production, but newer technologies could sequester 25 to 30 percent.

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 ...
