[0002] The ball mill is a key equipment for crushing materials after they are crushed. It is widely used in cement, silicate products, new building materials, refractories, fertilizers, ferrous and non-ferrous metal beneficiation, glass and ceramics and other production industries to dry or wet grind various ores and other grindable materials. The internal liner of the ball mill is used to protect the cylinder from direct impact and friction between the grinding body and the material. At the same time, different forms of liners can also be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material. According to the Chinese utility model patent (application number: 202320760402.6), a liner of a ball mill is disclosed, including a plate body, a plurality of grooves are provided on the plate body, a mounting port is provided in the center of the plate body, and a connector is provided at the end of the plate body. When the ball mill grinds the material, the steel balls are driven to rotate by the plate with multiple grooves, and fall downward when reaching the highest point of the ball mill to achieve the purpose of grinding. However, the device still has the following problems: the device increases the height of the steel balls by setting the grooves, thereby improving the grinding effect. However, due to the increased height of the steel balls, a greater impact force will be exerted on the liner, and greater noise will be generated.
