Polysius has already delivered four ball mills, and the two HPGRs should arrive in the March quarter of 2010. The JV partners, Perth-based Gindalbie Metals and China's Anshan Iron & Steel (Ansteel), plan to start production of direct shipping hematite in early 2011 and of magnetite concentrate by mid-2011.
A variable speed drive on large primary semi-autogenous mills can overcome this problem to a considerable degree. A major disadvantage of large semiautogenous mills has been the necessity to keep the mills fully loaded at all times to minimize ball and liner breakage.
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
