the treatment measures: to improve the service life of the jaw plate, jaw plate from the scientific choice of materials to start. In order to improve the service life of the jaw plate, the jaw plate should choose some good wear resistance materials, such as Zhejiang Shengda mechanical composite alloy jaw plate. In order to improve its wear resistance, our company developed the jaw crusher jaw plate is the use of high manganese steel (Mn13, Mn18), manganese chromium alloy (Mn13Cr2, Mn18Cr2) or new composite materials, in a scientific and strict smelting, Casting, heat treatment process, can resist severe abrasive wear.
