It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, glass and ceramics and other production industries. It can grind various ores and other grindable materials by dry or wet method. Ball mill is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to different discharge methods, it can be divided into grid type and overflow type.

[0003] When the ball mill is working, it uses the power generated by the movement of internal steel balls to crush the materials. However, since the material particles at the inlet of the ball mill are relatively large, the wear intensity of the inner wall of the ball mill is relatively high, which will reduce the service life of the ball mill.
