BASIC CEMENT PLANT LAYOUT – Process Cement Forum
Ball mills are suitable for low and medium moisture content in the range of five to six percent and are preferred for abrasive material. The main advantage of VRM is higher grinding efficiency and the ability to accept material with higher moisture content. Normally the energy consumption level in VRM is 10 to 20 percent lower than in ball mills.
