2016-7-12 circulating load calculations in closed crushing circuits were ex- ploited to achieve graphical estimation of these parameters. Three basic charts were proposed and constructed. Thefist one ir for the regular closed circuits where the new feed goes to the crusher. The second is for the reverse closed circuits

2013-1-1 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.
2016-2-29 A final calculation is now performed to arrive at the amount of original feed which, when added to the circulating load, will equal the capacity rating of the crusher at each trial setting. The formula for this calculation is: (III) Tones of fresh feed = Crusher Capacity / (1 + Circulating Load
