Alex G. Doll C O N S U L T I N G L T D TECHNICAL MEMORANDUM November 28, 2019 TO: UBC MINE331 CLASS FROM: ALEX DOLL, ALEX G DOLL CONSULTING LTD. SUBJECT: SAG MILL + BALL MILL CIRCUIT SIZING Summary: Most large tonnage mineral processing facilities consist of a primary SAG milling and secondary ball milling grinding circuit.

Doll (Doll, 2012) considering the various power losses in the transmission system. The estimated SAG mill power includes a correction for the interstitial mill filling. In the case of the estimated ball mill power, the power was calculated using the Bond methodology. Table 4 shows the principle parameters obtained.

For two-stage AG/SAG/Ball mill circuits, the primary mill transfer size is not an input for specific energy modelling, but it is rather an outcome of the ore characteristics and performance of the milling circuit given the operating conditions (configuration, feed size, mill speed, ball charge, grate design etc.).

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 ...

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.

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)

· 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.
