Cutting-Edge Grinding Solutions

In cement manufacturing, the grinding process is of utmost significance, as it entails the comminution of clinker, a raw material composed of calcium carbonate, silica, alumina and iron oxide. This pivotal process converts the raw material into a finely ground powder known as cement, a fundamental constituent in concrete production.

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 ...
