The surging phenomenon of the balls in the mill was confirmed by the photo graphic analysis. Based on this result, it is predicted that the grinding mechanism in the planetary ball mill consists of compressive, abrasive and shear stress of the balls, which is believed to be effective in producing very fine particles.

2019-12-15 Based on these observations, a mechanism that explains the relatively rapid nitridation of hafnium during high-energy treatment in a planetary ball mill is proposed and discussed. 2. Experimental. Nitride synthesis. Hafnium powder (LLC “OCHV”, purity 98%, Russia; particle size 40–60 μm), and nitrogen gas (LLC “NII KM”, Russia, purity 99.999%) were used as the initial precursors. High-energy ball milling (HEBM) was performed using a double-station planetary ball mill

1994-8-10 Planetary ball milling was investigated as a method of comminuting presintered thoria (ThO/sub 2/)-urania (U/sup E/O/sub 2/) granules for the preparation of sinterable feed powders. The experimental results indicated that planetary ball milling offers significant size-reduction rate advantage over conventional wet ball milling.
