  • Ball Mill Crushing Mineral Processing Metallurgy

    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. (5.5 to 6.7 m.) in length.

  • Whats the Difference Between Ball Mill Rod Mill and SAG

    The biggest feature of SAG mills is the large crushing ratio which can crush and grind the materials to 0.074mm at one time accounting for more than 20% to 40% of the total product. The crushing ratio can reach 4000 5000 which is more than ten times higher than that of the ball mill machine and rod grinding machine.
