Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

United Nuclear Black Powder Manufacture

Turn on your Ball Mill and let it rotate for 2 to 4 hours. As the Ball Mill rotates, the lead balls will crush the chemicals together and reduce them into a super fine powder. The longer you let it grind, the stronger your Black Powder will be. Let the Ball Mill do its grinding in an uninhabited area, not in a place like your bedroom.
