At 23 rd speed at which centrifugation just occurs is called the critical speed of the ball mill. At this speed the balls are carried almost to the top of the mill and then fall in a cascade across the diameter of the mill. By this means the maximum size reduction is obtained by impact of the particles between the balls and by attrition .

mm and speed about 1200 rpm of the clamp motion the ban velocities are high on the order of 5 ms and consequently the force of the balls impact is unusually great. Therefore these mills can be considered as high-energy variety 16. Planetary Ball Mills . Another popular mill for conducting MA experiments is the ball mill
