an 8 m diameter SAG mill with LID = grinding a copper ore, and predicted maximum capacity and minimum kWh/ton at about 6070 ball load at 25070 total filling. Two FAG mills of LID = 2 were necessary to give the same capacity, and the simulations indicated a lower kWh/ton for these mills. For this ore, both systems were technically feasible.
