  • Influence of ball size distribution on grinding effect in

    5/1/2014· From Table 5 we find that, the uniformity coefficient n and the characteristic diameter x 0 increase with the rise of the large size balls’ proportion in ball size distribution, that means when the ball size distribution is Φ16:Φ10 = 3:7, it will lead to a wider range of particle size distribution and smaller particle size than other four groups of ball size distributions.

  • THE OPTIMAL BALL DIAMETER IN A MILL

    The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
