The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.

2013-04-01· The relative capacity of a closed ball mill circuit as function of circulating load was calculated for three different classification arrangements: 1. cyclones with 38% of fine material reporting (by-pass) to coarse product (cyclone underflow), 2. screens with 20% of fine material reporting to coarse product (screen oversize), 3.

Cited by: 13For a closed circuit ball mill flowsheet as represented in Figure 2, a simplified relationship (Equation 1) for relative capacity at different circulating load and classification efficiencies was

Spreadsheet-based simulation of closed ball milling circuits

Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) Semi-Autogenous Mill Note the size of the mill: Why does the diameter need to be so big [image: (135-6-2)] SAG Mill Circuit Example — Gold Processing

2019-10-20· Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to

2009-08-27· with the overflow going to the flotation circuit. Cyclone 1 underflow constitutes the fresh feed to the second milling circuit that runs in closed circuit with its own cyclone (Cyclone 2). Ball mill 2 discharges to a sump where water is added before the slurry is
