1. the wear resistance of alumina ceramics. Because during the use of the ball mill, the surface of the inner tank is constantly rubbed against the grinding ball, which is easy to wear. Therefore, it is necessary to choose alumina ceramic materials with high hardness and good wear resistance.
2. the chemical stability of alumina ceramics. In the process of ball milling, some chemical reactions may be involved, and alumina ceramics need to have good chemical stability and are not easy to be corroded and dissolved.
3. the thermal stability of alumina ceramics needs to be taken into account. During the use of the ball mill, the frictional heat of grinding minerals is very large, and the lining material needs to be able to withstand such high temperature resistance.
4. the manufacturing process and cost of alumina ceramics. Various types of alumina ceramic materials, their preparation costs and processes are different, need to choose the right alumina ceramic materials to meet the required performance requirements, and be able to prepare within a reasonable cost range.
