[0002] The ball mill is mainly used for grinding materials. In the production process of powder products of rare earth oxides, ball mills are often used in the grinding process. Existing ball mills mainly use a horizontally or vertically arranged cylinder and a grinding body arranged in the cylinder. The grinding body rolls in the cylinder and collides with the material, thereby grinding the material into powder. A discharge port is set at the bottom of the cylinder, and the material is connected to a lifting pump after being screened through a filter, and then circulated to the cylinder for further grinding. Since the cylinder of the ball mill is filled with zirconium balls, the discharge port is easily blocked during the mixed grinding of zirconium balls and materials, resulting in failure of the lifting pump, inability to circulate the ground material, reduced grinding effect and production efficiency, and increased production costs. Therefore, there is an urgent need for an anti-clogging vertical ball mill. Summary of the invention
