2021-6-14 Fig. 20 Megapact vibratory ball mill. Courtesy of Battelle Memorial Institute. Impact forces acting on powders in a vibratory mill are a function of the rate of milling, amplitude of vibration, and mass of the milling medium. High-energy milling forces can be obtained by using high vibrational frequencies and small amplitudes of vibration.
