In June 1998, the world's largest grinding mill, the 40 ft (12.2 m) diameter 20 MW Cadia gearless SAG mill, was commissioned. This was a leap of over 40% above the largest operating SAG mill. A significant saving in capital cost gave the incentive necessary for a single mill line at Cadia, resulting in the selection of the 40 ft (12.2 m ...

As the SAG model in JKSimMet does not take account of the variation in breakage rates at different mill loads, the SAG mill load for different A and b values (Table 5) is kept the same as in the base case (Table 4). Simulated throughput was compared with the base case and the results are presented in Table 6, Table 7).
