systems in raw material, coal, and cement grinding. While new plants mainly focus on highly energy-effi cient systems, using roller comminution systems like vertical roller mills (VRMs) and high pressure grinding units (roller presses), less effi cient ball mills and combined grinding systems (pre-grinder plus ball mill) are still widely used.
