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].

Fault 2: Mining ball mill reducer bearing heats up. Reason: One of the possible reasons for the ball mill reducer bearing heating is insufficient lubrication. Insufficient lubrication can cause bearings to operate at high temperatures, resulting in overheating. Another cause could be excessive load or improper installation.
