During the last decade, semi-finish-grinding plants have been used more and more for the energy efficient grinding of high-quality cement. In 1999, it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantly. It was obvious, too, that the L/D ratio

Low filling degrees and low percentage of critical speed do not allow an efficient ball charge action on the material. High filling degrees and high percentage of critical speed lead to ball charge centrifugation and very little grinding efficiency. Mills with high percentage of critical speed can be operated with low filling degrees
