Gyratory Crusher Mantle for Primary Crushing
Mn18 / Mn22 | TiC Inserts Available
Heavy-duty gyratory mantles engineered for mining applications. Designed for extreme compressive loads, consistent wear performance, and extended service life.
What Is a Gyratory Mantle?
The gyratory mantle is the primary wear component mounted on the main shaft of a gyratory crusher. It performs a continuous gyratory motion, crushing material against the concave segments to achieve primary size reduction.
Designed for high-capacity mining operations, gyratory mantles must withstand extreme compressive forces, heavy impact loads, and abrasive materials.

Our cone crusher liners include mantles, concaves and bowl liners manufactured from high manganese steel for demanding mining and aggregate crushing applications.
Key Functions of the Gyratory Mantle
• Performs primary crushing in large-scale mining operations
• Maintains consistent material flow and throughput
• Works together with concave segments to form the crushing chamber
• Ensures stable performance under continuous heavy loads
Manganese & Composite Materials for Gyratory Mantle
High Manganese Steel (Mn13–Mn22)
High manganese steel remains the industry standard material for cone crusher wear parts due to its impact-induced work hardening properties. Under high compressive and impact loads, the surface rapidly hardens while maintaining a tough core structure, ensuring excellent resistance to abrasion and impact fatigue.
We supply multiple manganese grades tailored to specific crushing conditions:
• Mn13Cr2 – Cost-efficient solution for medium impact and secondary crushing
• Mn18Cr2 – Enhanced wear life in high-impact applications
• Mn22Cr2 – Ultra-high manganese for extreme duty and large primary cones
Relative wear life increases with impact energy and feed hardness.
Micro-Alloy Cone Crusher Liners
Micro-alloyed manganese liners incorporate controlled additions of chromium, molybdenum or other strengthening elements to refine grain structure and improve toughness. This technology increases wear resistance while maintaining the work-hardening capability of traditional manganese steel.
Compared to standard Mn22 liners, micro-alloy solutions can extend service life by 20–30% in abrasive hard-rock conditions.
Suitable for:
• Copper ore
• Hard granite
• High reduction ratio crushing
Titanium Carbide (TiC) Inlay Cone Liners
TiC inlay cone crusher liners combine ultra-hard titanium carbide inserts (up to 2800 HV) with a manganese steel matrix. The carbide rods provide extreme abrasion resistance, while the manganese base absorbs impact energy.
Key advantages:
• 2–3× wear life in abrasive secondary and tertiary crushing
• Reduced liner change frequency
• Lower total cost per ton
• Ideal for quartzite and ultra-hard rock
Not recommended for uncontrolled large primary feed where point-load impact is excessive.
Cone Crusher Liner Material Selection Guide
Selecting the right manganese steel grade is critical for crusher performance and wear life. The following guide compares common cone crusher liner materials and their typical applications.
| Material | Hardness | Impact Resistance | Typical Applications |
|---|---|---|---|
| Mn13Cr2 Manganese | 200–240 HB (work-hardens to 450–500) | High | Limestone, secondary crushing, moderate impact |
| Mn18Cr2 Manganese | 210–240 HB (work-hardens to 500–550) | High | Hard rock secondary and tertiary crushing |
| Mn22Cr2 Manganese | 220–250 HB (work-hardens to 550–580) | Very High | Mining, coarse chambers, high impact conditions |
| Mn + TiC Composite | Mn base + TiC inserts | High | Highly abrasive rock, extended wear life applications |
Note: All cone crusher liners are manufactured from austenitic manganese steel, which work-hardens under impact and compression during operation. Surface hardness typically increases from around 200 HB to 450–580 HB, improving wear resistance over time. The optimal liner material depends on feed material, chamber design, and crushing conditions. Contact our engineers for material selection support.

| Moderate Wear | 1–2 mm CSS drift | 0–300 hours | Adjust CSS to maintain product size |
| Heavy Wear | 2–4 mm CSS drift | 600–900 hours | Plan liner replacement |
| Severe Wear | 4–6 mm CSS drift | 600–900 hours | Replace mantle and bowl liner |

Cone Crusher Liner FAQs
What is a cone crusher liner?
Cone crusher liners are wear parts installed inside the crushing chamber of a cone crusher. The two main components are the mantle and the concave (bowl liner). These manganese steel liners protect the crusher and crush material through compression.
What is the difference between a mantle and a bowl liner?
The mantle is the inner moving liner mounted on the main shaft, while the bowl liner (concave) is the outer stationary liner installed in the upper frame of the crusher. Material is crushed between these two surfaces during the crushing process.
What material is used for cone crusher liners?
Cone crusher liners are typically made from austenitic manganese steel such as Mn13Cr2, Mn18Cr2, or Mn22Cr2. These materials work-harden under impact and compression, increasing wear resistance during operation.
How long do cone crusher liners last?
The service life of cone crusher liners depends on factors such as rock hardness, feed size, crushing stage, and liner material. In most applications, liners may last from several weeks to several months.
When should TiC insert cone liners be used?
TiC insert liners are recommended for highly abrasive materials where standard manganese liners wear quickly. The TiC inserts increase wear resistance and help maintain the crushing profile longer.
How do I choose the right cone crusher liner material?
The correct liner material depends on the type of rock, crushing conditions, and crusher configuration. Mn13 is typically used for softer rock, Mn18 for general hard rock crushing, and Mn22 for severe mining conditions.
