Concave Segments for Gyratory Crusher
3-Stage Structure & Position-Specific Materials
Qiming Casting is a professional China-based foundry specializing in manufacturing high-performance gyratory crusher concave segments (bowl liners), the core wear-resistant components for primary gyratory crushers. Our 3-stage segmented liners are widely applied in mining, aggregates and quarry industries worldwide.
- Upper Intake Liners: Adopt premium high manganese steel, providing excellent toughness to resist heavy impact loads from large feed materials.
- Chamber Mid Liners: Made of high-strength alloy steel, balancing impact resistance and abrasion performance for the middle crushing zone.
- Chamber Bottom Liners: Produced with high-chrome steel, delivering maximum abrasion resistance for the high-abrasion lower crushing area.
We provide customized concave segment designs with precision profiling optimized for site-specific conditions. Using advanced liquid-quenched Ni-Cr-Mo steels, our liners outperform standard air-quenched products, extending service life by over 50%, reducing failure risks, maximizing crushing throughput, minimizing energy consumption and lowering total cost of ownership for crushing operations.
With strict dimensional quality control and full compatibility with mainstream primary gyratory crusher models, our concave segments help operators maximize crushing throughput, minimize energy consumption, reduce liner changeout frequency, cut maintenance and labor costs, and achieve a significantly lower total cost of ownership for primary crushing circuits.
Material Options for Gyratory Concave Liners
Gyratory crusher liners operate under extreme impact loading from oversized feed. Material selection prioritizes toughness and work-hardening capacity.

TF Alloy Steel Gyratory Crusher Concave Segments
Qiming Casting has independently developed the proprietary TF Alloy Steel series, engineered exclusively for manufacturing high-performance gyratory crusher concave segments (also known as bowl liners) fully compatible with all major brands of primary gyratory crushers worldwide. Strictly compliant with international standards including EN 10293 and ASTM A532, our TF Alloy Steel range covers TF40 to TF70 full grades, precisely tailored to the differentiated working conditions of the 3-stage concave structure: high-toughness grades for upper intake liners to withstand extreme impact loads, balanced strength-toughness grades for middle chamber liners under combined impact and abrasion, and high-hardness high-chrome grades for bottom chamber liners to handle extreme abrasive conditions, ensuring uniform wear and optimized performance across the entire crushing chamber.
Every set of our TF Alloy Steel concave segments is subject to strict full-process quality control, including 100% dimensional gauging for perfect fitment, 100% MT & PT non-destructive inspection to guarantee crack-free castings, and rigorous surface quality control. Compared with standard manganese steel liners, our TF Alloy Steel concave segments deliver over 50% longer service life, significantly reducing unplanned downtime, liner replacement frequency, and per-ton processing costs for mining, quarry and aggregate crushing operations.
