Ball Mill Crushing Mineral Processing Metallurgy

Ball Mill Crushing by tube mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30 mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length.
