    factor for ball mill product fineness to apply, the ball mill circuit P80 should be no less than approximately 70 µm (See reference by Bond, 1962). This (Bond) efficiency determination should not be applied to circuits with a P80 finer than 70 approximately µm, without making qualifiions. Please refer to the example(s) that follow.

  • The working principle of ball mill

    22/05/2019 · 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.
