  • The working principle of ball millMeetyou Carbide

    May 22 2019 · Therefore in the rolling ball mill the grinding efficiency is increased as the ball diameter decreases. It has been proven that the highest grinding efficiency can be obtained with a small ball of .mm diameter. However the ball diameter is too small to wear too fast and it is also difficult to discharge due to the small gap of the ball.
