Grinding mechanism of centrifugal mills — a

The results obtained by the simulation indicate that the grinding action of centrifugal mills is largely dissimilar from that of vibration mills and that centrifugal mills provide a much higher energy dissipation rate per unit volume of the charge compared to vibration mills at an equal centrifugal coefficient.
