Impact Crusher Hammer Wear Resistance

The hammer of the impact crusher plays an important role in the crushing of the material. The life of the component has an important influence on the efficiency of the production. Therefore, when designing the machine, we need to pay attention to the improvement of the wear resistance of the component.

The improvement of the life of the internal components of the impact crusher is an effective solution to reduce the occurrence of faults in the work and improve the efficiency, and the significant effect on the life improvement is mainly reflected in the wear parts, such as the liner, the counterattack, the hammer, etc. Because these components are directly involved in the production process, they have an important role in production. If any of these components fails, the production is difficult to carry out smoothly, so it is very important for the improvement of its life. To improve its life, it is necessary to improve its wear resistance. Here is an analysis of how the wear resistance of the hammer head is improved.

To improve the wear resistance of the hammer head, it is necessary to start from the material of its production. The hardness of the material is an important factor affecting the wear resistance. The hardness ratio of the material to the wear-resistant material Ha/Hm has a great influence on the wear rate. Starting to rise, the wear resistance is reduced. At this time, if the hardness of the material is constant, the hardness of the metal material can be improved to make the wear resistance significantly improved. Therefore, when the impact crusher is processed, the internal wear-resistant material is used. The choice is very important and directly determines the life of the part.

However, only increasing the hardness of the material does not necessarily improve the wear resistance of the material, because wear resistance is a comprehensive index, which is closely related to the hardness and toughness of the material. The toughness plays an important role in improving the wear resistance of the material. For the hammer of the impact crusher, toughness refers to the sign that the material itself absorbs the external energy. It is proved by production practice that the hardness of the hammer with the same hardness and the impact toughness is the same as the impact. After the increase in toughness value, we can find that to improve the wear resistance of the hammer head, we need to start from two aspects:

  1. 1. Increasing the hardness of the material of the hammer head will inevitably contribute to the improvement of the wear resistance, and the phenomenon of pear cutting of the metal surface can be alleviated;
  2. 2, improve the toughness of the material can inhibit the initiation and expansion of cracks, help to reduce the fatigue of the peeling, and thus improve the wear resistance.

The article mainly introduces the improvement of the wear resistance of the hammer of the impact crusher. From the above introduction, it can be found that to improve the wear resistance, it is necessary to start from two aspects, one is the improvement of hardness, and the other is The improvement of toughness, in order to improve these two aspects, can improve the service life of components and help the production to proceed more smoothly.
