The feed material was dry batch milled for selected periods ranging from 3; 5; 15; 30–90 min. For all the batch tests, the mill feed was kept constant at 1941g and after each duration the mill was stopped and the contents offloaded. This was then followed by separation of the product from the grinding media on a wire mesh.

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.
