Roller Crusher Roller Shell
High Manganese Steel Wear-Resistant Roller Shell | Impact Resistant · Long Service Life · Stable & Efficient
Product Introduction
The roller crusher roller shell (also known as roller skin) is the core wear-resistant component of the roller crusher. Its performance directly determines the crushing efficiency, operation stability and maintenance cost of the equipment.
The Mn18Cr2 high manganese steel roller shell produced by Shandong Hengtai Intelligent Manufacturing is made of high-quality alloy steel raw materials through a water toughening treatment process of not less than 1040℃. It has both high wear resistance and high toughness, and is suitable for medium and fine crushing operations of medium and high hardness materials.
This product is widely used in mining and smelting, building materials, highway, railway, water conservancy and chemical industries. It can crush various ores and large materials with compressive strength ≤ 320MPa, and is an ideal choice for high-load continuous operation conditions.
Core Performance Advantages
Superior Wear Resistance
Made of Mn18Cr2 high manganese steel with high manganese and chromium content
A dense hardened layer is quickly formed on the surface under material impact and extrusion
Wear resistance is significantly improved compared with Mn13Cr2 roller skin
Stronger wear resistance to high-hardness ores, effectively extending the service cycle
Strong Impact Resistance & Non-Cracking
The core maintains a stable austenite structure with excellent toughness
Combined with centrifugal casting process, the structure is dense, free of pores and inclusions
Can withstand high-frequency impact and extrusion of large hard materials
Effectively avoid chipping, block falling and early failure during operation
Stable Operation & Long Service Life
Uniform hardness distribution after water toughening treatment
Strong resistance to mechanical and thermal shock
Suitable for long-term continuous high-load operation
Reduce downtime for replacement and lower maintenance costs
Service life is significantly better than ordinary high manganese steel roller skin

Frequently Asked Questions (FAQ)
Q1: What is the main function of the roller crusher roller shell?
The roller shell is the core wear-resistant component of the roller crusher, which directly undertakes the extrusion and crushing of materials. Its performance determines the crushing efficiency, finished product particle shape, equipment stability and overall maintenance cost.
Q2: What are the advantages of Mn18Cr2 high manganese steel roller shell compared with ordinary roller shells?
Mn18Cr2 high manganese steel has higher manganese and chromium content. Under strong impact and extrusion, it can quickly form a high-hardness work-hardened layer, and its wear resistance is significantly better than that of ordinary high manganese steel roller shells such as Mn13Cr2.
Q3: Is the roller shell prone to cracking or block falling?
No. The product adopts centrifugal casting process and water toughening treatment of not less than 1040℃, with dense structure and high toughness, which can effectively avoid chipping, block falling and early failure.
Q4: What materials is this roller shell suitable for?
It is suitable for medium and high hardness materials with compressive strength ≤ 320MPa, including granite, river pebbles, iron ore, shale, gangue, cement clinker and construction waste, etc.
Q5: What crushing working conditions is it suitable for?
It is suitable for medium and fine crushing working conditions, especially for high-load, continuous operation production lines, such as mining, sand and gravel plants, cement plants and construction waste treatment projects.
Q6: How long is the general service life of the roller shell?
Under the same working conditions, its service life is significantly better than that of ordinary high manganese steel roller shells, which can effectively reduce the frequency of shutdown replacement and lower comprehensive maintenance costs. The specific service life is related to material hardness and working conditions.
Q7: Is the hardness of the roller shell uniform?
Yes. After standard water toughening treatment, the overall hardness of the roller shell is evenly distributed, which not only ensures surface wear resistance, but also takes into account internal toughness, making the operation more stable.
Q8: Is customization available for different models of roller crushers?
Yes. Non-standard customization can be carried out according to the roller crusher model, roller diameter, roller width and working conditions to ensure installation matching and optimal crushing effect.
Q9: What improvements can be brought to production after replacing the roller shell?
After replacing with high manganese steel wear-resistant roller shell, the equipment runs more smoothly, the crushing efficiency is higher, the discharge particle size is more stable, and the loss caused by shutdown maintenance is significantly reduced.
Q10: Is this roller shell suitable for export projects or overseas working conditions?
Yes. The product has stable wear resistance and impact resistance, and has been widely used in high-intensity working conditions such as mining, building materials, highways and water conservancy, meeting the long-term operation needs of export equipment.
