A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

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