Ball Mill Circulating Load Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries Compared to Solids or Density based Circulating load equations a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios
In practice circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent It may appear strange at first sight that the circulating load between a mill and classifier producing for example 100 tons of finished product per day can be as much as 400 tons or more but this will be made clear by Fig 71
