conversion costs. the potential benefits of converting an overflow mill to a grate discharge will frequently far outweigh the downsides. in operations needing improved grinding circuit performance, the ability to fully utilise the available installed ball mill power will enable higher throughput, a finer grind, or a combination of the two, which will lead in turn to increased production

fine grinding, to p80 sizes as low as 7 m, is becoming increasingly important as mines treat ores with smaller liberation sizes. this grinding is typically done using stirred mills such as the isamill or stirred media detritor. while fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mills energy budget
