Now the crusher hammer head on the market can be divided into two types based on the manufacturing process: casting and forging, but their wear-resistant degree is not the same. Hammer crusher also can be classified according to the material species: high-manganese steel hammer, bimetallic composite hammer, large gold teeth hammer head, chromium alloy hammer and other high manganese steel with alloy material. The alloy hammer head has good wear resistance. However, the process is complex and costly.
Currently widely used material is a white cast iron, the material having a high hardness and wear resistance, tensile strength, flexural strength is equivalent to the modulus of elasticity, but the white iron has relatively poor toughness, it is difficult to use the impacting force under large working conditions. Improve the toughness to eliminate the shortcomings greatly improves the material strength and toughness as well as wear resistance.
