Calculating a grinding circuit's circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill and hydrocyclones, .
overflow that is similar to the final ball mill product, and the phantom cyclone underflow is then used as an adjusted ball mill feed for the ball mill power calculation. ... can be determined by a simple mass balance, i.e. by subtracting a proportion of the final product (P) from the AG/ SAG mill product size distribution (T) as follows:
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating .

Consider the balance around a classifying cyclone: Thus, the volumetric yield to the underflow stream can be obtained from the following expression: Formulas for figuring the balance around a classifying cyclone [diagram 135-2-1] Slurry Solids Concentration by Weight. A classifying cyclone is treating 150 gallons/min of slurry.
two ball mill-cyclone circuits of Los Pelambres Mining. • The SAG line 1 presented a balanced distribution 50% - 50% for the ball mills BM 4 and BM 5, during the surveys. • SAG line 2 showed an unbalanced condition, where the feed flowrate to the BM 6 circuit was higher than the flowrate to .
Additionally, floating the coarser cyclone underflow stream reduces the chance of gangue entrainment (Allen, personal communication, 2015), allowing a higher grade flash concentrate. It is also worth mentioning that a typical mill discharge mass flow is larger than the cyclone underflow mass flow.
