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.

Classification liner for the second chamber of the ball mill

The second chamber of a ball mill is mainly for fine grinding. Therefore, using small balls was known to be more efficient as this increases the surface area of media and improves the grinding effect. For the conventional mill using a liner with lifter, however, it was difficult to reduce the ball diameter drastically because the grinding efficiency is extremely lowered by reverse ...
