Ball Mill Crushing by tubemills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. ( to m.) in length. Pebbles were used as a grinding medium and the mills were lined with either silex blocks ...

The most common machines for the comminution of coarse feed material (primary crushers) are the jaw crusher (1m > P 80 > 100 mm), cone crusher (P 80 > 20 mm) and hammer crusher. Primary crusher product in intermediate feed particle size ranges (100mm > P80 > 20mm) can be ground in autogenous (AG) or semiautogenous (SAG) mills depending on feed properties and application requirements.
