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 Cmodel or Nordberg equation to get the RPM that corresponds to 75% for that mill diameter.

Wilczek: The mill accepts a maximum particle size of about mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 1020 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.
