At the same time, the dredging rod reciprocates and moves up and down to dredge the feed pipe to prevent the feed pipe from being easily blocked and difficult to discharge. Manual processing and dredging of the feed pipe are required, which makes the grinding and discharging time longer, greatly delays the production and processing time, and affects the work efficiency to a certain extent. The present invention has a simple and reliable structure, good grinding effect on the negative electrode material of the lithium ion battery, is easy to control, and is suitable for promotion.
