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.
