Formula Of Ball Mill Process

Ball Milling Theory Introduction Figure 1 Ball milling terminology. I was first given the formula for gunpowder by my Uncle at age 14 after he had observed my apparent obsession with class C fireworks. Being a scientist who had experimented with the ancient recipe himself during his youth he thought I should try making my own fireworks.
