Crusher machine life depends on the quality of spare parts, crusher machine parts, hammer is an essential part. Now the the crusher hammer on the market is generally divided into the casting and forging. Vico crusher long high-manganese steel hammer, good toughness, good technology, and to improve the wear resistance of the crusher, and thus extend the life of the crusher.Domestic and foreign large and medium-sized jaw crusher motor fixed jaw plate and side guard, hammer crusher hammer impact crusher board hammer and counterattack board, more high manganese steel as the main material. In general, the harder the hammer its wear resistance is also greater. To improve the abrasion resistance of the hammer bit, it is necessary to increase its hardness, but with the improvement of the hardness, the hammer impact toughness will be reduced.
Therefore, how to reconcile the hammerhead a suitable hardness and good impact toughness improve hammerhead abrasion is the key. Vico has long insisted crusher high manganese steel hammer, extend the life of the crusher. High manganese steel, good toughness, good technology, low prices, its main feature is the greater impact or contact stress under the surface layer will quickly generate work hardening, work hardening index is 5-7 times higher than other materials, has been greatly improved wear resistance, which can effectively extend the crushing time.
In addition to the use of raw materials, hammer crusher hammer manufacturing quality, structural design, technical parameters and feeding conditions are factors impact crusher life.
