Sep 01, 2013 As the feed size is reduced further, less of the 50.8 mm balls and more of the 25.4 mm balls are required for the maximum capacity, attaining 100% of 25.4 mm balls for a feed size of 4.7 mm (Fig. 6d).Circulating load calculation in mineral processing closedJan 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. Bond Efficiency-GMG-ICE-v1-r04 Determining thedard Circuit, assume 2.44 m diameter overflow mills, and use a rod mill F80 of 16,000 µm and a rod mill P80 of 1,000 µm. Note that—in order for no correction factor for ball mill product fineness to apply—the ball mill circuit P80 should be no less than approximately 70 µm (Bond, 1962). This
