ball mill comminution

Nov 01 2002 · Earlier work by Fuerstenau and Kapur on the comminution of quartz in a singleparticle 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
