Ball-milling – Nanoscience and Nanotechnology I
These centrifugal forces operate on the powder mixture and the balls, resulting in fracturing and cold welding of the powder mixture. The milling balls can attain impact energies of upto 40 times more than that caused by the gravitational acceleration, in normal directions. Thus, planetary ball milling can be employed for high speed/energy milling.

Planetary ball‐milling of AlON powder for highly transparent ceramics
A detailed investigation of planetary ball-milling for coarsened AlON powder was carried out. Our results showed that the weight ratios of milling ball-to-powder, the revolution rate and the planetary ball-milling time have significant impacts on the microscopic morphology, particle size distribution and average particle size of powder.
