The high manganese steel crushing wall of the cone crusher has become an important part of the equipment due to its good wear resistance. High manganese steel (usually containing 11-18% manganese) has a unique self-hardening property, that is, during the force process, a hardened layer will gradually form on the surface of the crushing wall with friction, thereby significantly improving its wear resistance. This hardened layer can effectively resist the continuous wear from high-hardness materials such as ore, sand, and gravel, greatly extending the service life of the crushing wall. In addition, the design of the crushing wall also takes into account the addition of alloying elements such as chromium (Cr), molybdenum (Mo), and nickel (Ni), which not only enhance the hardness and toughness of the steel but also improve its impact resistance, ensuring that it is not easy to crack or break in a high-intensity working environment. The addition of chromium and molybdenum also makes the crushing wall have strong corrosion resistance, which can effectively prevent material corrosion when facing high humidity, high temperature, and crushing operations containing corrosive substances, further improving its wear resistance.
