Quick and Easy Black Powder Ball Mill — Skylighter, Inc.

The critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding. At some point in this pyro-art adventure, we start to hear or get the feeling, that we need a ball mill to grind chemicals very fine or to make high-quality black
