How To Deal With Jaw Crusher Jaw Plate Problems

Zhejiang Shengda Machinery Co.,Ltd | Updated: Oct 19, 2017

Jaw crusher as a more extensive use of crushing equipment, in the course of the work of the key parts of the Jaw Crusher Jaw Plate prone to serious wear and tear, thereby reducing the jaw plate life and jaw crusher efficiency. Zhejiang Shengda Machinery on the jaw crusher jaw plate wear serious causes and treatment measures for a detailed analysis and introduction.

First, the cause of the malfunction: jaw plate wear jaw crusher is the main form of failure, the general jaw plate life is short, large consumption, need to reserve a large number of spare parts in order to maintain normal research and development, high research and development costs.

Jaw crusher jaw plate of the short life of the main factors are: jaw plate material selection is not appropriate. Jaw plate material often use high manganese steel, its toughness is good, high strength, process is good, have a certain hardness, in the larger impact or contact stress, high manganese steel surface layer will quickly produce severe hardening, greatly Improve surface hardness and wear resistance. But the actual use of the impact or contact stress is often enough, can not make the surface quickly produce hardening, wear resistance can not be fully brought out.

Second, 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.

Under the same working conditions, Zhejiang Shengda mechanical composite alloy jaw plate at least more than high manganese steel jaw plate more than 1 times, but the quenching and tempering heat treatment process is the key, it also greatly improve the jaw plate life.
