A new methodology to obtain a corrected Bond ball mill work …
The standard Bond ball mill test requires a material of appropriate granulometric composition, −3.35 mm created by a stage-crushing process, which is ground in a ball mill. A small number of very brittle ores can naturally generate very fine sizes, in spite of being correctly prepared.

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 a mill's …
