What are the materials used for the impact crusher hammer?


Hammer is one of the most important wear parts of impact crusher, excellent product need qualified wear hammer. The material and casting process have important influence on the life of wear plate hammer. Proper hardness and impact toughness is the key factor to improve the wear resistance of crusher hammer. So how to choose the correct material we really need?


The most common materials of wear resistant plate hammer are: high manganese steel, high chromium cast iron, inlaid hard alloy rod.

 First, the greater the size of the impact crusher, the greater the fragmentation is ,the impact load of the plate hammer will be greater. Under these circumstances, you should first consider how to improve its hardness.

Second, according to different material (such as granite,quartzite, and limestone),plate hammer material should be different, the higher the hardness of the material ,the higher hardness plate hammer should be.

Third, in the selection of plate hammer material, consideration should be given to the cost of the material and strive to achieve high quality and low price. So we could win the market. At the same time, we should also consider the rationality of the process, so it will be easy for the factory to organize production and control quality.

For the impact crusher, the material fo the hammer is a fundamental factor. In order to extend the service life of the hammer, we must grasp the correct selection of materials, laying the foundation for the high quality of the plate hammer.
