The Role of Crusher Liners

Crusher liners is an important part of the crusher. It is usually installed in the crushing chamber of the crusher, directly in contact with the crushed material, commonly used in cone crusher, jaw crusher, impact crusher, gyratory crusher. its main functions include:

1. Protect the crusher body: Reduce the wear and impact of materials on the crusher body and prolong the service life of the crusher.

2. Improve crushing effect: Through reasonable liner shape and design, it can optimize the crushing process of materials and improve the crushing efficiency and product quality.

3. Enhance the crushing force: Change the trajectory and force state of the material to enhance the effect of crushing force.

The materials of crusher liners are mainly as follows, and the performance characteristics of each material are as follows:

1. High-manganese steel: Manganese crusher liners have good toughness and work-hardening properties. When subjected to heavy impact and extrusion, the surface will harden rapidly, thus improving wear resistance. However, under low impact load or low stress wear conditions, the work hardening effect is not obvious, and the wear resistance may not be as good as some other materials.

2. Alloy steel: Alloy steel crusher liners higher hardness, high strength, wear resistance is better. Through the reasonable proportion of alloying elements, you can get different performance, adapt to a variety of working conditions.

3. Wear-resistant cast iron: With high hardness and certain toughness, relatively low cost. However, in the extremely harsh wear environment, its wear resistance may be slightly inferior.

4. Ceramic composite materials: Ceramic composite series, including high manganese steel ceramic composite materials, alloy steel ceramic composite materials, high chromium ceramic composite materials. Extremely high hardness, excellent wear resistance and good chemical corrosion resistance. However, ceramic composite materials are more brittle and may be prone to fracture under strong impact.

The crusher wear part selects different materials with different wear resistance and strength characteristics to adapt to different crushing conditions and material characteristics. Its shape and structure are also various, such as corrugated, serrated, etc., to meet different crushing needs.

In practice, the selection of crusher wear liners requires comprehensive consideration of the crusher working conditions, the type of material to be crushed, the cost and other factors to achieve the best results and economic benefits.
