The 18% manganese liners used prior to the trials lasted for a maximum of 12 weeks (16,800 tonnes through crusher). The first trial liners using hardfacing lasted 38 weeks (53,200 tonnes through crusher), providing 216% extra life. As this proved such a success, it was decided (correctly) that a lower-cost manganese could be used.
medium manganese, i.e., 18% manganese content along with 2% chromium, is becoming famous due to its increased mechanical properties and improved wear life [2]. Initially, British metallurgist Sir R Hadfield first developed the manganese steel in 1882 and observed that AMS achieved high toughness when Mn levels were

Force analysis. The main function of the ball mill liner is to protect the mill and use the convex peak of the liner to play the ball to grind and crush the material. Therefore, the main failure mode of the liner is abrasive wear under the repeated impact of small energy. Fig. 1 shows the motion diagram of grinding ball and material.

As rocks meet the surface of the manganese steel its exterior layer hardens. This results in a material that is harder to wear down during operation and can handle higher impact blows compared to other alloys. However, it is a common misconception that higher percentages of manganese content within an alloy result in a more robust wear part.
