A Review of the Grinding Media in Ball Mills for Mineral …
pharmaceutical industries normally use dry grinding whereas the mineral processing in-dustry mostly resorts to wet-milling. In mineral processing, grinding, which is key to the liberation of valuable minerals from gangue, is achieved in primary, secondary and ter-tiary applications as well as regrind mills.
Variables affecting the fine grinding of minerals using stirred mills
Fine grinding is a relatively new area and considers grinding below 30 μm down to around 10 μm. Below 10 μm, the term "very fine grinding" can be used. The energy consumption in ball milling rises sharply for grinding products below 75 μm and below 30 μm grinding using ball mills becomes uneconomical.

Energy Use of Fine Grinding in Mineral Processing
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 …
Grinding Mills
Ball mills are used extensively for grinding metal bearing ores and abrasive minerals. When grinding ore prior to concentration, on the other hand, the grind is determined by the degree of reduction necessary to unlock the valuable mineral from the gangue.
