INCREASING SAG MILL CAPACITY AT THE COPPER

Copper Mountain first feed to the SAG mill occurred in late May, 2011. The circuit began ramp up in mid-June of that year, with more consistent operating run times on the SAG and Ball mills. Plant throughput in the first months was quite variable with throughput tonnage greater than 40,000 tons one day and less than 25,000 the next on some

SAG Mill Grinding Circuit Design

Jun 06, 2016 By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the

What's the Difference Between SAG Mill and Ball Mill

Nov 26, 2019 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

How HPGRs compare to conventional milling

Aug 19, 2019 Within comminution circuits, High Pressure Grinding Rolls (HPGR) are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional reduction methods, but their wearable
