7. Clinker Grinding. The next step will be to grind the clinker because now it has lowered in temperature. This is done inside a ball mill where it is further mixed with a small proportion of Gypsum. Gypsum is important because it acts as a regulator of the cement's setting time and prevents it from early hardening after the addition of water.

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 ...

a Loesche mill, with a grinding track diameter of only 1.1 metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical roller mill did not take place until the beginning of the 1990's. 1935 The first Loesche mill for grinding cement clinker, an LM 11, was commissioned in Joao Pessao, Brazil.
