  • ACTTR Inc.Principle of Ball Mill Operations

    Nov 27 2020 · A ball mill rotates its long shaft and drive a jar which is placed on it. The friction of the rubber surface of the shaft can rotate the jar. The grinding beads (grinding balls) in the jar will constantly hit the sample due to gravity and mechanical force. After a long period of rotation and impact the sample gradually changes from large pieces to small pieces and small pieces to powder.
