20191126 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s

202048 The mill’s SAG/ball/flotation circuit was initially designed for 35,000 mt/d. As mentioned earlier, a secondary crushing circuit had been installed to boost the mill tonnage rate to 40,000 mt/d. However, the increased circulating load led to overloading of the original 12 x 28ft singledeck SAG mill discharge screen.

The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from oversize discharge product (critical size “pebble” discharge) that is screened out and may be stockpiled or requires secondary crushing prior to reintroduction to the SAG mill
get priceThroughput optimisation in milling circuits
SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification hydrocyclone variables (feed density, flow and pressure) and water feed rate to the sump. Model predictive control (MPC), which is a multiinput multioutput (MIMO) controller, is very suitable for this purpose.
