A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical.

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed.

The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet dry). None of the characteristics of the material being ground have any influence on K 1.
