1.Improve the hardness of the jaw plate: the larger the jaw crusher specifications, the greater the lumpiness of the broken material, the greater the impact load of the jaw plate. At this time, when choosing the material, we should first consider improving the hardness of the jaw plate under the premise of ensuring its toughness.
2.Consider the hardness of materials: the jaw plate should be different for different broken materials (such as granite, quartzite and limestone); The higher the hardness of the material, the higher the hardness of the jaw plate.
3.Considering the strength of moving plate and fixed plate: moving plate and fixed plate force and wear mechanism is different, the moving plate bears the impact force is larger, therefore, the toughness should be considered first; The fixed plate is supported by the frame, so hardness can be given priority.
4.Consideration of technical and economic effects: DENP also takes technical and economic effects into consideration when selecting jaw plates, striving to achieve high quality and low price and market competitiveness. At the same time, the rationality of the process should also be considered to make the production plant easy to organize production and control the quality.
