Product Description

Use: impact crusher

Material: high manganese Mn13%,Mn14%,Mn18%.etc

Features: low abrasion, high resistance

There are different kinds of spare parts for impact crusher. Among them, liner is one of the most important spare parts. The liner is easily to be worn out. Therefore, the liner materials should be required to have both very high hardness surface to resist the drilling and cutting of ore and very high strength and toughness to resist impact extrusion.

Tips

The function of impact liner of impact crusher

Impact liner is the most important part of impact crusher. Impact liners are the wearing resistant part of the crusher. They are installed on the crusher frame and they protect the crusher frame in the meanwhile.

When the impact crusher is working, the crushing material was fed into the crushing chamber. The crushing material will firstly hit the blow bar on the rotor. The crushing material will be crushed once. Then the crushing material will hit the impact liners and rebound straight to the blow bar. This process will be repeated until the crushing material is discharged.


The impact liners are installed to prevent the crusher frame from wearing. For the whole crusher liners, the cost of impact liner is much less. It is easier and cheaper to exchange one impact liner than the whole crusher liners when they are worn and that is one of the functions of the impact liner.


The main reasons of why liners will be worn

Impact crushers are the the common equipment in mining industry. Liners are the wearing parts of the impact crusher equipment. This article will introduce the main reasons of why liners will be worn.

The liners suffer from great forces: While the impact crusher is working, the fixed liner, the swing liner and the crushing material are forcing each other. The surface of the liners are suffering from complicated stress. The drilling, cutting and impact extrusion are the main way of wearing.


1. The operating conditions are harsh: Because of the job nature of the impact crusher, the liners will be worn unavoidably. If the impact crusher is under harsh operating conditions, it will exacerbate the wear of the liners.


2. Hardness and grain size of ore is different: According to the difference of the hardness of crushing material, the damage degrees of the liner will be different. The harder of the crushing material, the much force liners will suffer. When hardness is the same, the bigger of the feeding grain size, the more serious liner will be worn.


3. The way of feeding material is improper: If the feeding machine of the impact crusher equipment hasnt installed properly or the feeding material is too much, crushing chamber will be blocked by the material or any other problems. This will make the liners suffer from great forces, and strengthen the wearing of the liners and the liners will be worn seriously.
