Ball milling replaces potentially unsafe hand grinding of chemicals and compositions. The crushing of the material is accomplished by the repeated falling of heavy balls onto it, over and over, inside the mill jar. So, it sounds like I need a ball mill. I want my chemicals to have small particle size and be intimately mixed. What are my choices?

A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5axis mill, you can try "Sturz" milling to combat the slow moving tip. See below for details.
