In a unit volume of mill, the rate of ballonball contacts per unit time increase as ball diameter decreases, because the number of balls in mills are increased. Thus, the rate of breakages of HGP are more for smaller diameter balls and for larger diameter balls, the rate of breakages for EGP is lesser making ball milling as efficient.
