SM500 × 500 cement ball mill (a) The cement ball mill (b) Instrumented grinding media. The filling ratio, ratio of particle to ball and mineral weight were varied to control the mill load. The initial ratio of grading ball was 30 mm: 40 mm: 50 mm: 70 mm = 30: 20: 30: 20.

mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.
