how to calculate circulating load in ball mill – stone cruxder

By calculating this ratio, you can determine whether your system is operating optimally or if adjustments need to be made. To calculate the circulating load ratio, divide the mass of solids in each stream by their respective flow rates. The sum of these ratios represents the overall circulating load ratio for your ball mill.
