(1) hammer crusher working principle of material falling from the feed inlet into the crushing chamber, and the high-speed rotary hammer with impact material was broken at a rapid rate in a certain impact on the grate, larger size After repeated crushing materials, after crushing the material to meet the requirements of small to exclude crack through the grate. (2) analysis of hammer crusher hammer wear during operation, in addition to being hit, but also by the material erosion bimetallic hammer in such long-term repeated use, the work surface hammer would be destroyed, it is deformed, if used on reversible crusher, hammer edges on both sides will be ground into a smooth circular surface. Hammer crusher in the early work surface shape changes as the hammerhead mainly by the impact of wear, the material in the positive impact force shaping metal surface deformation and impact craters. When the hammer of the working face ground into the arc, then the surface stress changes, metal migration from the hammer surface erosion wear, resulting in failure of the hammer. Despite the impact of material can produce a certain amount of wear is not enough, and ultimately makes the hammer failure in the initial work. Thereby increasing the hardness of the hammer, hammer wear resistance can be improved, thereby reducing the impact of wear and improve the toughness of the material helps to suppress the generation of cracks and expansion will help reduce erosion wear. Therefore, the choice of what kind of wear-resistant material is the basic way to improve the life of hammerhead. High chrome hammer almost hard cast iron and nickel simultaneously developed. As early as 1930, the United States conducted a high chrome hammer Metal hammer, due to the high chromium content, so when on the one hand cupola melting chromium and carbon combine easy, not easy to control the carbon content; the other hand, due to the easily oxidized with chromium oxide cupola burning hammer, making a low yield of chromium, therefore, in the melting furnace is still very rare cases, high chrome hammer unable to obtain large-scale applications. After World War II manganese steel hammer, along with large-scale use, high chrome hammer furnace before they get a larger development and applications. Adding chromium to make a mesh M3C carbide structure type type type M7C3 become isolated, and the carbide hardness increased from M3C of 840 ~ 1100HV to M7C3 of 1300 ~ 1500HV, which not only improve the wear resistance , but also improve the toughness, their effectiveness is higher than the nickel hard cast iron. Therefore, since the advent of high chrome hammer, has been the task is an ideal wear-resistant materials, the application has been widely promoted. Our world in the early 20 70s, high chrome hammer achieved good economic benefits mining, building materials and other industrial applications. High chrome hammer often divided hypoeutectic and hypereutectic two categories, the current high chrome hammer commonly used in industry generally hypoeutectic. Hypoeutectic high chrome hammer, the eutectic carbides were isolated strips off the distribution network, thus hypoeutectic high chromium hammer with high wear resistance and relatively poor toughness, can be used to produce bear has the impact of conditions in certain parts. And hypoeutectic high chromium hammer compared hypereutectic high chromium and carbon content hammer high volume chromium carbide volume fraction increased significantly improve the wear resistance of the material can promote. Hypereutectic high chromium hammer appeared coarse primary carbides, resulting in high chrome hammer toughness sharp decline in casting and heat treatment process easy to crack, so that the hammer reject rate increases, currently hypereutectic hammer Applications little. But with too refined and improved toughness hammer eutectic carbides, the future will continue to expand the range of applications.
