    Effect Ofmilltype On Thesize Reduction Andphase

    Sep 29 2015 air jet milling is found to be the most effective in reducing particle size from a d 90 of 37 m to 29 m compared to planetary ball milling 302 m and single ball milling 105 m xrd and tem studies confirm that the planetary ball mill causes phase transformation to the less desired alumina resulting in a notable decrease in surface area from 1366 m 2 g to 825 m 2 g as measured
