The starting point for ball mill media and liquid charging is generally as follows 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...
This weight value is a close approximation of the weight of your mills optimum charge lets say it weights 150 grams. That means each time youre going to mill BP in the future the only thing you have to do is to weight out 112.5 grams of bulk KNO3, 22.5 grams of bulk charcoal and 15 grams of

The drum I used for the ball mill was originally a plastic container that held abrasive grit used in vibratory tumblers. It is about two liters in size. I had several empty containers of this type, and decided to put them to use in this project. They work pretty well in this application. There are a few potential problems.
