You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have a drying function besides grinding.

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.
