Impact Crusher Hammer

The Function of Impact Crusher Hammer

The impact crusher uses the plate hammer on the high-speed rotating rotor to impact and crush the materials fed into the crushing cavity at high speed, and throw the crushed materials to the impact plate at the other end of the crushing cavity along the tangential direction at high speed, then crush again, and then rebound to the plate hammer. In this process, it mainly depends on the impact crusher hammer to strike the material and initially crush the material.

The Material of the Impact Crusher Hammer

When the carbon content is higher than the upper limit, more carbides can be found in the structure of impact crusher hammer. The hardness after heat treatment is higher, reaching HRC55~60, but the toughness is significantly reduced. Compared with the high manganese steel, it can not bear a large impact load. Therefore, as the materials of impact crusher hammer, the content of 42CrMo should not be too high. Since the impact crusher hammer is easy to wear, it's necessary to choose the material with high wear resistance when selecting.

Improvement Measures of Impact Crusher Hammer

In order to improve the operation efficiency of equipment, Nile Machinery has already upgraded the wearable part of the impact crusher hammer. The specific method is to change the theme material of the impact crusher hammer to high manganese steel ZGMn13 and inlay three pieces of tungsten-cobalt alloy YG6 on the top of each impact crusher hammer with an angle of about 20 degrees. Because the tungsten-cobalt alloy YG6 has high hardness and good wear resistance performance, which can improve the yield strength and wear resistance of impact crusher hammer.
