how to select the best comminution circuit

Otherwise, it is a pretty broad range for a SAG/AG mill to cover. If you cannot, my personal choice (not necessarily the best) would be to consider on a small 3000 TPD plant like this; jaw or gyro crushers, rod mill + ball mill or maybe no rod mill and just a grate discharge ball mill with an oversized cone crusher ahead of it (if material ...

Sag Mill Advantages

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

sag mill power calculations grind

The software looks at the primary and secondary grinding stages and sees how much power is available in each stage. For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW ofpower drawavailable for a total of ratio of 10:15 (1:1.5)

MEI''s Barry Wills: SAG ''15 Conference Diary

 · At that time the grinding circuit featured the largest of a kind SAG mill at 12.2m x 7.92m and two 8.2m x 13.6m ball mills. The plant met the nameplate capacity in late 2011 but had some challenges in upstream and downstream plant areas. It was good to see Dave at the conference, another of my mid-1980s CSM students.
