A Review of Advanced Ball Mill Modelling ... (Morrell, 2004). These different approaches have one thing in common: they use a single number to describe energy in grinding. This number, the specific energy, is the ratio between the power and the throughput in the case of continuous sys-

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.

SAG mills, Morrell (1993). The mill with scats had a considerably finer size distribution, and notably lacks ball in the 40mm to 60mm size range. This is the size at which the porosity is exposed, and they suddenly become smaller and non-spherical. For a normal finer ball size distribution a finer grind and lower throughput would be expected.
