The variation of ball size in a planetary ball mill (PBM) was studied in terms of its effect on the specific impact energy of balls as a result of ball to ball and ball to vial collision calculated through a .
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.
Ball mill. A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
