[0002] The grinding operation is an important link in mineral processing. The quality of the grinding operation products directly affects the mineral processing indexes. The feeding of the ball mill has a great influence on the whole ball milling operation. When adding grinding feed and grinding media, they are both added through the ball mill feeding port. During the adding process, the materials and grinding media will impact or wear the inner wall of the ball mill feeding port. After running for a period of time, the inner wall pipeline of the ball mill feeding port will be worn through, resulting in material leakage. Only the whole pipeline of the ball mill feeding port can be replaced or the severely worn part of the pipeline can be repaired from the outside to ensure the normal operation of the ball mill, increasing the minor repair frequency of the concentrator, increasing the unplanned downtime of on-site production, and being unfavorable to the production and management of the concentrator. And mainly at the inner bottom of the feeding port pipeline at the site, and the wear degree of other parts is relatively small. Therefore, it is urgent to research and develop a new anti-wear device for the ball mill feeding port to extend the service life of the ball mill feeding port. Content of the Utility Model
