ball mill particle size reduction

  • Effect of mill type on the size reduction and phase

    Sep 29, 2015· Air jet milling is found to be the most effective in reducing particle size from a d90 of 37 µm to 2.9 µm compared to planetary ball milling (30.2 µm) and single ball milling (10.5 µm).

    balls, so that the size reduction is minimal (Fig a). High angular velocities: The ball are thrown out on to the mill wall by centrifugal force and no size reduction occurs (Fig.b). At about 2/3 of critical angular velocity: centrifuging occurs, a cascading action is produced (Fig. c). Maximum size reduction occurs by impact of the particles
