Impact energy of particles in ball mills based on DEM
It has been shown that the grinding of ball mills of different sizes follows the first-order kinetics. Although different collision environments exist with different sizes of mills, impact energy is a useful index that determines the grinding rate. Regardless of the mill size, for a given material, a unique correlation exists between impactVarious devices have been used for processing B powder, including attritor mills, conventional planetary mills, tumbler mills/mixers, vibratory mills, shaker mills, and uni-ball mills [161][162(PDF) Process Engineering with Planetary Ball Mills

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 Download. The Planetary Ball Mill PM 100 is a powerful benchtop model with a single grinding station and an easy-to-use counterweight which compensates masses up to 8 kg. It allows for grinding up to 220 ml sample material per batch.
