Hammer crusher during operation, due to the continued impact and friction materials, inevitably hammer, liner, grate and other parts wear out and fail, and thus use of funds, and waste materials, impact crusher normal production. hammer wear on the factors were analyzed to help targeted solution. causing hammer crusher hammer wear failure of the main factors in the following three: the impact of domestic building materials industry hammer crusher hammer ① condition of most of them high-manganese steel materials. when the crusher at a high energy impact, hammer surface hardening phenomenon will generate a substantial increase in the surface hardness. but in fact, when the hammer at work suffered little impact stress, hammer hardening phenomenon was not significant, the surface layer does not form a larger hardness of the hard skin. charming hammer will be a lot of material from micro cutting, while there will be impact fatigue pits, eventually led to the hammer wear. ② general material impact hammer, hammer hardness greater wear resistance is greater. to improve the wear resistance, it is necessary to increase Raymond Mill the hardness, with the increase of the hardness, impact toughness is reduced. the main features of high-manganese steel is in contact with a large impact or stress, the surface layer will quickly produce hardening, wear resistant surface layer is formed. eventually leading to the potential of the hammer not fully wear high manganese steel, reducing service life. ③ affect the chemical Portable Crusher composition of the high manganese steel hammer chemical composition has a decisive influence on its mechanical properties and wear resistance. selected reasonable proportion of ingredients to improve the quality hammer, can effectively improve the life of the hammer. adding a certain amount of chromium in high manganese steel hammer can be greatly strengthened and improved organizational performance hammer, hammer improve life.
