deagglomerated by a hammer mill, ball mill or a V-separator (see Figure 3). A HPGR can reduce energy consumption when working as a pre-grinder ahead of a ball mill, with savings of around 1.8-2.5kWh/t for clinker and 2.5-3.8kWh/t for GBS.10 Conclusion To reduce the clinker factor while still developing concrete strength requirements,

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.

Breakthrough in Clinker Grinding

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. The
