Fine grinding, to P80 sizes as low as 7 μm, 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 mill's energy budget. Overall energy use and media ...

Ball mills tumble iron or steel balls. The balls are initially 5 to 10 cm diameter. They gradually wear away as grinding proceeds. Ball mills typically contain about 75% ore and 25% 'steel' (by volume). They give a controlled final grind. The ball mill accepts the semiautogenous or autogenous mill product. It produces uniformsize flotation feed.
