Sometimes it is also used in the production of some Chinese herbal medicines, and the herbal medicines are crushed by ball mill.

[0003] Publication number CN205761471U discloses a tiltable ball mill for traditional Chinese medicine, comprising a machine body and a base, the machine body comprising a barrel body and a control device, a feed funnel opening is arranged on the upper part of the barrel body, discharge openings are arranged on the bottom of both sides of the barrel body, both sides of the barrel body are connected to the disc through connecting rods, the other side of the movable turntable is fixedly connected to the control device, an adjusting knob is arranged on the control device, a timer is arranged on the upper part of the adjusting knob, and an adjusting rod is arranged on the lower part of the control device.

[0004] In the above documents, the Chinese medicine is ball-milled by means of a stirring rod. This method is relatively simple, and it is easy for large pieces of Chinese medicine to remain inside the cylinder during ball-milling, which leads to the fact that the ball mill's grinding effect on the material is not very ideal. During the long-term grinding process, more Chinese medicine residues will adhere to the inner wall of the cylinder, which may affect the later grinding of other materials. Utility Model Content
