[0002] The ball mill is mainly used for grinding materials. In the production process of rare earth oxide powder products, the ball mill is often used in the grinding process. The existing ball mill mainly uses 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 the zirconium balls and the material, resulting in failure of the lifting pump, inability to circulate the ground material, reducing the grinding effect and production efficiency, and increasing production costs. Therefore, there is an urgent need for a ball mill with side lifting circulation. Summary of the invention

[0006] The lifting mechanism includes a lifting cylinder; a stirring motor is provided on the top surface of the lifting cylinder, the stirring motor is connected to a stirring shaft, the stirring shaft extends to the bottom of the lifting cylinder, and a spirally wound lifting blade is provided on the stirring shaft. When the stirring motor drives the stirring shaft and drives the lifting blade to rotate, a vortex negative pressure is formed, and the powder material is sucked into the lifting cylinder from the discharge port, and is transported to the feed port through the lifting blade to realize the circulation grinding of the powder material.

[0007] Furthermore, two sides of the grinding cylinder are respectively connected to the frame on that side through connecting pieces.

[0008] Furthermore, the grinder is provided with stirring shafts evenly distributed on both sides of the grinder, and the stirring shafts are arranged in the grinding cylinder.
