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.
