Ball Mill from Skylighter TL5005 It is the ball-milling which will give our powder the power we need. Ball-milling the black powder ingredients ensures a very small, fine particle size. This maximizes the surface area of the ingredients, and the resulting burn speed. After milling, the ingredients are also extremely intimately mixed.
