    The Three Types of Ball Mills Minerallurgy

    Aug 21 2021 Ball mills are often operated at higher speed than rod mills so that the larger balls cataract and impact on the ore particles. The work input to a mill increases in proportion to the speed and the ball mills are run at as high a speed as is possible. Applications. Ball mills are used extensively in the mechanical alloying process.
