A Grinding Ball Mill is a type of grinder used to grind and blend materials for use in mineral processes. A Grinding Ball mill 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.

The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for high-speed milling. Schematic view of motion of the ball and powder mixture.
