Planetary ball mill includes a disc and vial(s) rotating on top of a disc in planetlike movement,, the disc and the vials rotate in the opposite directions similar to planets rotation around the sun (Fig. ); as such the centrifugal forces act in like and opposite direction alternately. This total centrifugal force acts on the material ...

High energy ballmill can also induce phase transformations in precursors such as: amorphization or polymorphic transformations of compounds, disordering of ordered alloys, etc., however, all these have similar chemical compositions. Alloys can be prepared by using different equipments such as, attritor, planetary mill or horizontal ball mill.
