Prediction of 3D slurry flow within the grinding chamber

2012-12-1  SAG mill geometry and operating conditions. To explore three dimensional slurry flow in a SAG mill, including discharge through the grates and flow in the pulp chamber, we use a pilot scale Hardinge 6 ft (D) × 2 ft (L) (1.8 m × 0.6 m) mill.

What's the Difference Between SAG Mill and Ball Mill

2019-11-26  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

Copper Mountain Advances Mill Expansion With SAG

2020-4-8  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 28-ft single-deck SAG mill discharge screen.

Freeing up milling capacity in a SAG mill & ball mill

The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from over-size discharge product (critical size “pebble” discharge) that is screened out and may be stockpiled or requires secondary crushing prior to re-introduction to the SAG mill

Throughput optimisation in milling circuits

SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification hydro-cyclone variables (feed density, flow and pressure) and water feed rate to the sump. Model predictive control (MPC), which is a multi-input multi-output (MIMO) controller, is very suitable for this purpose.
