In Germany, cement finish-grinding is currently mostly conducted in ball mills (over 100 mills, some of which are over 40 years old). Finish-grinding of cement on much more energy-efficient vertical roller mills is already widespread internationally, especially in greenfield projects, but is hardly ever practiced in Germany (less than five mills).
