You can fill the container with about as much of the substance you want to grind but leave some empty space for things to move around. Make sure to periodically oil everything up. This is a good time to make sure everything is running smoothly. Running a ball mill is quite noisy so it is a good idea to operate it in a closed room or basement.

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.
