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.
The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as …
Slide 3 circulating load ratio : As the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit. Circulating load circulating load ratio New feed circulating load ratio [8] 4.
Then the circulating load ratio is equal to 'A' divided by 'B', the number of passes through the mill needed to generate the total amount of new circuit product. Example: A ball mill circuit product (cyclone overflow) contains 80% passing 75 um (200 mesh). The circuit feed (from the previous stage of size reduction) contains 20% passing 75 um.

The adopted hydrocyclone flow split parameter was 83.74%. This indicates that 83.74% of the hydrocyclone feed returns to the mill as circulating load. Considering the new feed is equal to 482 t/h, the calculated circulating load was equal to 2,482.33 t/h, being necessary 177 iterations for the calculation.
Circulating load ratio and ball mill circuit performance makes the optimisation objective seem nebulous to both plant metallurgist and designer some of this confusion can be eliminated by taking a step back from the overwhelming detail of sharpness of separation curves circulating load ratios cyclone feed pressures vortex and apex sizes etc .
"The circulating load ratio is necessary to determine the capacity of the ball mill initially. Once the ball mill is installed, you cannot change its capacity" The underflow is circulated into the ball mill as shown in the figure "The underflow is not a waste; it is further sent to the ball mill operation for further recovery of the ...

that accumulate during each pass through the mill. Low circulating load equates to long mill residence time and the buildup of fines. Another factor that plays a role is the breakage characteristic (the tendency to create fines during a breakage event) of the ore.
