The Effect of Grinding Media on Mineral Breakage Properties Hindawi
网页2021年12月11日Grinding is used to primarily liberate useful minerals and secondarily provide fine ores with a proper particle size for separation. Gaudin [ 9] developed a mineral liberation model for breakage, but it considered materials only as cubes of equal volumes in an excessively simplified mineral mosaic relation.

Energy Use of Fine Grinding in Mineral Processing SpringerLink
网页2013年12月18日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
