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.
