Effect of ball and feed particle size distribution on the ...
Jun 01, 2018 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.

Ball milling: a green technology for the preparation and ...
Ball milling was performed for 24 hours at 1000 rpm. With this pretreatment, the resulting nanocrystals had a spherical shape with a 100–200 nm diameter and a 3–7 nm height, rather than a rodlike shape. This demonstrated that the applied pretreatment was a determining factor in the morphology and particle size of the resulting CNCs.
