Critical rotation speed for ball-milling
To examine the dependence of critical rotation speed on ball-containing fraction, we measured critical speeds at various ball-containing fractions from 0.3 to 0.95 stepped by 0.05. Since at lower fraction than 0.3 we could not observe the centrifugal motion, we chose this fraction range. A jar of ball-mill consists of a cylinder and two lids.

Effects of the speed ratio on the efficiency of planetary mills
4. Conclusions. The influence of the ratio ( k) between the rotational speed of the supporting disc ( ωd) and vials ( ωv) at different ωd and BPR on the milling efficiency of a Pulverisette 4 planetary mill was studied. The milling efficiency was determined indirectly by measuring the ignition time (t ig) for the formation of TiB 2 from its ...
