Clinker size and cement grinding | GCP Applied Technologies

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 in some cases the formula will result in the prediction that 100mm balls be used to deal with large clinker particles.
