The SPEX ball mill was carried out at a speed of 1000 rpm. SPEX ball mill was proved to be much more efficient than the planetary ball mill. The rate of grinding in SPEX mill was significantly greater than the planetary because of the differences in the energy levels, working principles, and rotation speeds. The milled powder of SPEX ball …
DEM calculations performed for a Retsch 400 PM planetary mill operated with standard vials at 350 rpm, show that when the number of milling balls increases above 50, the balls move as organized two-dimensional structures. The organization of the balls into structures dramatically changes the energy dissipated in collisions.
