Ball mill circulating load

Ball mill circulating load

CONCLUSION The circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and HPGR circuits. This is a well-known fact for ball mill circuits that has been recognised for almost 100 years. For HPGR circuits the knowledge is more recent, and is still being investigated

    Jan 01, 2013 A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution

    It can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250% to 600%. This is because of the reduction in classification efficiency from 50% to 30% as calculated by Eq. (11). Compared to the ''reference point'', a ball mill

    Feb 21, 2015 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
