A study on the effect of ball diameter on breakage

2016-7-20  volume of mill, the rate of ball-on-ball contacts per unit time increases with the increase in ball diameter, because the number of balls in the mill increases as 1/d3. Thus, the rates of breakage of smaller sizes are higher for smaller ball diameters. The relation with T a and ball diameter in a 0.6 m diameter mill were given as aT α 1/d 9.
