Classifying efficiency plays an important role in grinding efficiency. High classifying efficiency means that those qualified grains can be discharged timely and efficiently,while low classifying efficiency means that most qualified grains are not discharged and sent to the ball mill for re-grinding, which is easy to cause over-grinding and ...

large influence on the grinding efficiency. In this case, the optimum %<75 µis in the region of 73.4% or 1.989 kg/l (see Graph 3). If one goes below that, the higher dilution will 'flush' the fines out of the mill and reduce the overall residence time in the mill. This will result in a coarser grind with a slightly

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.
