The mass of two mill charges and the number of revolutions per given circulating load was equal, and mill speed was kept constant (the one in the standard test mill, 70 rpm). More feed was added to the Relo tests to reach the steady state (desired circulating load) due to the Relo media's apparent higher grinding kinetics.
Irrespective of the sampling, it was possible to visually notice a large amount of material between 25 and 76 mm in the mill load during inspection shutdowns. At the time, the circulating load was approximately 20% to 25% of fresh ore fed into the SAG mill, at a rate of approximately 1,100 – 1,200 tons/hour.

retaining gravity recoverable gold within the grinding circuit resulting in high circulating loads of gold (Banisi, Laplante and Marois, 1991). The retention of GRG within the grinding circuit allows for effective gravity recovery of gold from within the grinding circuit. A typical partition curve for both the ore and GRG, presented in Figure 3,
• Circulating load will depend on mill capacity and target grind size. – worn apex can increase load unnecessarily (leads to inefficient grinding) Vortex Increases cutpoint and water split to Finder overflow, reduces pressure coarser overflow, lower circ. load Apex Decreases cutpoint and water split to overflow increased amount of water and ...

(this should also reduce the circulating pebble load in the SAG circuit). If your ball mill is drawing less than the full installed power while operating, add grinding steel - if the mass of additional steel drives the bearing pressure higher, it should be offset at least partially by reduced solids loading.
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 load ratios and circulating load tonnage on tons/day or tons/hour. This is %Solids/Densities ...
