  • The energy efficiency of ball milling in comminution

    Earlier work by Fuerstenau and Kapur on the comminution of quartz in a single-particle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22 . Thus as a mechanical device for producing fine particles the ball mill is reasonably efficient energetically.
