Change the original grindability. Step#2. More crushing and less grinding to reduce the feed size into mill. Step#3. Reasonable filling rate of steel ball. Step#4. Reasonable size and proportion of steel ball. Step#5How To Calculate The Efficiency In For Mill SizingThe mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the materials 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.
