volume of mill, the rate of ballonball 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 m diameter mill were given as aT α 1/d 9.

CONCLUSION: As a conclusion, the higher the speed of the sets, the higher the products amount produced in desired size range. The high amount of products produced can also be because of the longer duration of the sets in ball milling process. However, the speed has more effects on products produced compared to duration of the sets in this experiment.
