Circulating Load Calculation Formula· 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 The trend to the use of higher
Ball Mills Mine Various classifiers such as screens spiral classifiers cyclones and air classifiers are used for classifying the discharge from ball mills This formula calculates the critical speed of any ball mill Most ball mills operate most efficiently between 65% and 75% of their critical speed Photo of a 10 Ft diameter by 32 Ft long ball mill in a Cement Plant Photo of a series of ball mills in a
