    The conversion of the 80 of initial hematite to amorphous phase during extended dry grinding by tumbling planetary and vibratory mills needs 4000 8500 and 50 000 kJ/kg energy respectively. It was understood that vibratory mill introduces the minimum lattice strain and gives the largest crystallites when applying the same level of stress energy.
