Large-size media are required to fracture particularly hard particles in the mill charge; smaller media fill the voids and promote finer grinding. For continuous grind applications or batch mill, attending to media volume is advisable maintaining a 40-45% media charge (of mill volume) and keeping throughput constant will provide best results.

Energy Use of Fine Grinding in Mineral Processing

Dec 18, 2013 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.
