Fine clinker is less of an issue in a ball mill, since the material simply passes through to the second chamber for fine grinding, although this can reduce the impact of the 1st chamber crushing action somewhat. However, higher clinker fines content can often lead to harder grindability and so the target for less than 25% of clinker that is below 1mm in size is also appropriate for ball mills.
