Hammer crusher hammer crusher as the most important wear parts, hammer wear resistance is directly related to the efficiency of the crusher. For now, at home and abroad for the manufacture of hammer crusher wear-resistant materials are mainly 3, respectively, high manganese steel, low alloy wear-resistant steel and high chromium cast iron. Xiao Bian now to a brief introduction of these three materials produced by the hammer of performance advantages and disadvantages. First of all, we all know that high-manganese steel with hardening characteristics, however, the high manganese steel hammer in the actual work process by the force of mostly low-stress, the impact is not enough, resulting in the hammer surface height can not be rapidly hardening resistance hammer mill, will wear high manganese steel hammer poor long-term survival of the fittest choice after market trend, high manganese steel hammer trend gradually be eliminated. Second, low-alloy steel hammer bainite or martensite wear the majority of market requirements should arise, it is high hardness, good toughness, excellent wear resistance and low production cost, occupy a certain share in the current market. However, high wear-resistant low-alloy steel hardness, general hardness is too high brittleness increases, so will increase the risk of hammer breakage. In addition, the organization of low alloy wear-resistant steels no or only a small amount of high hardness carbide, so that the wear resistance of the hammer is still not ideal, can not meet the growing market demand for abrasion resistance. Finally, high chrome cast iron, with its excellent toughness and hardness is recognized as the current production hammer crusher ideal wear-resistant materials, and tissue contains a lot of high hardness carbide, so the service life of high chromium cast iron hammer high manganese steel hammer and low alloy steel hammer 4 to 6 times. Therefore, the high chromium cast iron hammer are replacing the traditional hammer on the market at home and abroad to become Nova mine currently on the market. However, due to the addition of high chrome hammer rare element leads directly enhance the production cost hammer, in addition, lack of high chromium cast iron hammer toughness will lead to frequent breakage is the case, it did not in this type of hammer industry market On the strong promotion. Bimetal composite hammer is my company developed in 2007 to develop wear-resistant hammer price of patented products, patent number: ZL201010547430.7. The hammer adopts dual-hydraulic EPC casting process, a cast molding. Low-alloy steel hammer handle part, has good toughness, not broken, hammer part of the high-chromium alloy with good wear resistance wear hammer model, the use of certain production processes will be both organic combination of large resistance hammer mill, so that the hammer while meeting the requirements of toughness and wear resistance. The hammer is suitable for crushing limestone, granite, pebbles, coal rigid material, the actual use of the results showed that the double-metal composite hammer than the ordinary high manganese steel hammer wear resistance 3-4 times.
