Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.

This study showed pronounced changes in the Raman scattering of silicon powder during high-energy ball milling. The powders were milled for 1–18 h in a steel ball mill in argon. The approximate pressure imposed on particles was 2 GPa. The spectra of the as-milled powders were compared with the initial silicon.

The ball milling induces heavy cyclic deformation in powders and promotes the formation of nanostructures by the structural decomposition of coarser-grained structures as a result of severe plastic deformation. Cryogenic ball milling (or cryomilling) can reduce oxygen contamination and minimize heat generated during the milling process.
