1. When the hardness of the material is higher, the hardness requirement of the hammer material is also higher, and the larger the material is, the higher the toughness requirement is. Therefore, the choice of hammer material should be paid attention to. Which requirement is more important for the fragmentation and hardness of the crushed material.
2. The larger the size of the crusher, the heavier the weight of the hammer, the greater the size of the crushed material, and the greater the impact load on the hammer. Therefore, when choosing the material of the hammer head, the toughness of the hammer head should be guaranteed first, and then how to increase the hardness of the hammer head should be considered on the premise of ensuring the toughness of the hammer head.
3. In addition to the above two points, there is another very important point, which is to comprehensively consider the rationality of the process, and consider the cost-effectiveness of the product, as well as the market acceptance, use effect, etc.
