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 ...

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
