### The energy efficiency of ball milling in …

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. Since single-particle breakage always produces a product with a distribution modulus of unity ...
