2020-11-27 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.

2019-11-26 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s
