In addition, it includes the engineering for two 15.6 mw GMD systems for two 26 ball mills. ABB Switzerland Ltd, Z rich CH, Tel. 41 58-586-8832, www.abb.com
In 1998 the worlds largest SAG mill and two of the worlds largest ball mills were commissioned at Newcrest Minings Cadia Hill property in New South Wales. The design of the comminution circuit and selection of mill sizes followed two years of study and evaluation of a wide range of alternatives, predominantly using simulation techniques.
Each mill is equipped with a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From startup, the mill struggled to meet the required production rates. Over time, a major initiative that involved blasting and fragmentation, optimization of the SAG mill in terms of discharge grates, ball size and slurry
