  • Ball Mills an overview ScienceDirect Topics

    Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.Choosing Ball Milling Media for Firework Chemical Milling,So, I am choosing the half-inch lead balls to mill with in this example.
