What material is best for jaw crushing plates? ——Analysis of hot topics on the Internet in the past 10 days
Jaw crusher (jaw crusher) is the core equipment in mining, building materials and other industries. The material selection of its tooth plate (also called jaw plate) directly affects the equipment life and production efficiency. Recently, the discussion on the material of jaw breaking plate has become more and more popular all over the Internet. This article combines the hot industry data in the past 10 days to provide you with an in-depth analysis of the best material selection plan.
1. Core performance requirements of jaw breaking plate material
The die plate needs to have high wear resistance, impact resistance and corrosion resistance. Common materials are divided into the following three categories:
| Material type | Representative brand | Hardness(HRC) | Wear resistance | Applicable working conditions |
|---|---|---|---|---|
| High manganese steel | ZGMn13 | 18-22 | medium | Medium and low hardness materials |
| alloy steel | Cr26 | 58-62 | excellent | High hardness materials |
| Composite material | Tungsten carbide + steel base | ≥65 | Excellent | extreme wear environment |
2. Comparison of material performance hotly discussed on the entire network (data in the past 10 days)
According to statistics from a machinery forum, the comparison of the three material properties that users are most concerned about is as follows:
| Contrast Dimensions | High manganese steel | alloy steel | composite materials |
|---|---|---|---|
| average service life | 3-6 months | 6-12 months | 12-24 months |
| Crushing cost per ton | 0.8-1.2 yuan | 0.5-0.8 yuan | 0.3-0.6 yuan |
| Market purchasing popularity | down 17% | up 23% | up 41% |
3. Latest recommendations from industry experts (updated in 2024)
1.granite broken: Cr20Mo2TiB alloy steel is recommended, its impact toughness is 40% higher than traditional materials
2.Iron ore processing: Nano-modified high chromium cast iron (Cr30) has become a new trend, with wear resistance up to 3 times that of ZGMn13
3.Construction waste disposal: Bi-metal composite die plate can handle the mixed wear of steel bars and concrete at the same time
4. User feedback on real cases
A comparative test at a Zhejiang sand and gravel plant shows:
| test group | Material | Processing capacity (10,000 tons) | Wear amount (mm) |
|---|---|---|---|
| Group A | Mn13 | 12.5 | 38.7 |
| Group B | Cr26 | 24.3 | 21.5 |
5. Precautions when purchasing
1. Confirm the Mohs hardness of the material (it is recommended to test the material composition)
2. Pay attention to the manufacturer’s heat treatment process (isothermal quenching can increase the service life by more than 30%)
3. New surface strengthening technologies (such as laser cladding) can reduce maintenance costs
in conclusion:At present, alloy steel has the best comprehensive cost performance, and composite materials are the future development direction. It is recommended to choose according to the specific working conditions, regularly check the wear of the tooth plate, and replace it in time to avoid damage to the equipment host.
