Thus, in this case the ball mill grinding circuit resulted in 99.9% efficiency, which is here considered abnormally high. Another selected performance index was the by-pass or fine removal in the desliming stage. The calculations indicated a 69% by-pass of the 0.010 mm fraction which was here regarded as a very low efficiency.

maximize this rate. 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
Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
