I use alumina or zirconia milling media, and don't worry a bit about ball-milling single chemicals. Mixtures, on the other hand, I don't mill (except, rarely, BP with brass or 300 series stainless steel milling media; and all this remotely and behind barricades). I never mill chlorate or perchlorate mixtures; it's not if but when it goes wrong ...

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
