A ball mill is a type of grinding machine that uses steel or ceramic balls to grind materials into a fine powder. It works on the principle of impact and attrition. Impact occurs when the balls are lifted by the rotating mill and then drop onto the material to be ground. The force of the impact breaks the material into smaller pieces.
Planetary Ball Mills 101 from Union Process Inc. Planetary ball mills share the same design as other basic ball mills – a grinding jar filled with media and rotated on its own axis.

Under ideal working conditions, Raymond Mill consumes less energy than other ordinary grinding mills. For example, the MTM Medium-speed Grinding Mill only consumes 1.02kW/h when yielding a ton of materials and 1.48kW/h when feeding a ton of materials. Its electricity consumption is lower than that of ball mill at the same level by over 60%.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
