1, the choice of jaw crusher Material
Of non-metallic inclusions in steel will lead to the stress concentration of these inclusions are most likely to form cracks, thus reducing the contact fatigue life of the material. The edge of the internal defects of organization, materials, also have great impact on the wearer. Usually, fine grain, uniform, hard alloy material is spherical, is conducive to the improvement of the rolling process of bearing steel. The fatigue life after the residue to make the surface compressive residual strength should reduce the useful force and the carburized layer, making it easier to produce micro cracks. The undissolved carbides, by proper heat treatment, it tends to be smaller, small size, uniform thickness, avoid or banded carbide, have for Eliminate fatigue cracks
2, reduce the surface roughness of the bush
Practice proves that the appropriate to reduce the surface roughness of the pad is to improve the ability of anti fatigue wear, contact stress level and bushing surface roughness can withstand the high contact stress or jaw plate, effective method usually surface hardness requirement, is on the liner surface roughness is low.
