The ball mill working process is carried out in the cylinder. After the ball mill grinding media in the cylinder body is brought to a certain height with the rotation of the cylinder body, the ball mill grinding media falls due to its self-weight, and the raw materials in the cylinder body are severely impacted by the grinding media.
