Maintenance Measures for Crusher Liner
The lining used in the existing jaw crusher is generally ZGMn13, which is characterized by surface hardening under the impact load, forming a hard and wear-resistant surface while still maintaining the inner layer of the original metal. Its toughness, it is the most common wear-resistant material used on the jaw crusher.
Product description

The jaw crusher of the jaw crusher appears to be worn at the beginning, and the toothed plate can be used for turning the head, or two upper and lower heads can be used. The wear of the seesaw is mostly in the middle and lower parts. When the tooth height is worn off by 3/5, the root needs to be replaced with a new one. When the two side linings wear out 2/5, they also need to be replaced with new ones.
1 reduce the surface roughness of the liner
Appropriately reducing the surface roughness of the lining is an effective way to improve the fatigue wear resistance. The surface roughness requirements of the lining are related to the contact stress on the lining surface. When the contact stress or the surface hardness of the lining is high, the lining is applied. Surface roughness requirements are low.

2 liner shape
Tests on smooth surface liners show that under the same conditions, the productivity is increased by about 40% compared with the toothed liner, and the life is increased by about 50%; but the crushing force is increased by about 15%, and the crushed product size cannot be controlled, and the power consumption is Slightly increased. Therefore, for the crushed layered material, it is not suitable to use a smooth lining under the condition that the product has a high particle size. For the extremely hard material with strong corrosion, in order to extend the life of the lining, a smooth lining can also be used.
3 liner material selection
