The first comminution stage in a mineral processing plant is crushing, which reduces the size of particles from up to 1 m down to cm (depending on the type of milling circuit). Crushing is typically a dry process that makes use of Gyratory, Jaw, and Cone crushers (NapierMunn et al., 1996), which predominantly make use of impact mechanism.

MILLS USED IN MINING. Stamp mills were used in mining to crush ore from deep deposits into small pieces before further processing. The metal ores needed to be crushed down to a pea or walnut size before it could be smelted. At times, the mills were also used in metal working after the completion of the smelting while the metal was red hot.

Energy Use of Fine Grinding in Mineral Processing | SpringerLink

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 ...
