The impact crusher plate is one of the main wearable parts of the counterattack crusher, and it plays an important role in the work of the equipment. Due to the serious wear of the impact crusher plate, it is necessary to choose a material with high wear resistance when selecting the material. What are the types of the impact crusher plate? How to choose? We introduce the material of the impact plate of the impact crusher from the following two points.

Material type of impact crusher board
1, High manganese steel counterattack plate: The main feature is that under the action of *er impact or contact stress, the surface layer will quickly produce work hardening, and its work hardening index is 5-7 times higher than other materials, and the wear resistance is *er. The improvement. Therefore, the high manganese steel counterattack plate has good toughness, good manufacturability and low price.

2, High chromium alloy impact plate: It is a good wear-resistant material and has been widely used in impact crushers, but high chromium alloy has poor toughness and is prone to fracture without the support of a hammer frame.

3, Cemented carbide impact crusher plate: Compared with other materials, cemented carbide impact crusher plate has the characteristics of higher hardness, bending strength and impact, thermal fatigue resistance, good thermal hardness, and low cost. This kind of material impact crusher The board solves the problems of cracks, desoldering, cracking, and falling blocks that are easy to appear in high manganese materials.

Selection of counter plate material
1,Wear resistance: When selecting materials, the wear resistance of the material should be paid enough attention. The hardness of the material is an important factor affecting the wear resistance. The hardness ratio of the material to the wear resistance has a * influence on the wear rate.

2,Toughness: With the same hardness and different impact toughness, the wear resistance increases with the increase in toughness. Therefore, when choosing the impact plate material, you should choose good toughness.
