JowetP isaccepted, then ball milling isabout 80per centefficient. CONCLUSIONS It has been shown that ball milling isarelatively efficient process when compared with allother known comminution processes. There would seem tobesome evidence to support the validity of the proposal of JowetP that the standard of 100per cent efficiency should bebased onsome standard slowcrushing test. Theefficiency ...

Ball mill media optimization

The mill grinding efficiency can also be calculated by taking the ratio of the 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 ...
