Particle Size Distribution Effects that Should be ...
2016-6-8 Because of the wider size distribution produced from ball milling, they are almost always operated in closed circuit with classifi cation at full scale. Classifi cation results in more selective breakage of the coarser sizes because the fi nes are removed preferentially from the circuit and therefore a steeper size distribution curve is produced.

Effect of ball and feed particle size distribution on the ...
2018-6-1 For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
