Product Introduction

How Concave Liners Improve Crushing Efficiency
The concave liner is the stationary crushing surface in a cone crusher, working directly with the mantle to generate compressive force for ore reduction. Its geometry governs throughput stability, wear behavior, and final particle size distribution.
ZM INDUSTRY CO., LTD. designs crusher concaves specifically for mining liners applications where predictable wear and uninterrupted operation are critical. Using 400 BHN heat-treated alloy steel and engineered chamber profiles, our concave liners deliver controlled wear progression, reduced liner change frequency, and consistent crushing performance over long service cycles-ultimately lowering total operating cost per ton.

Quality Control
Fully Traceable Mining Liner Quality
Chemical Control
Each casting heat undergoes independent chemical analysis, ensuring alloy consistency and predictable wear behavior across all concave liners supplied.
Heat Treatment Traceability
Complete heat treatment graphs and logs per heat provide transparency, repeatability, and compliance with strict procurement standards.
Mechanical Validation
Mechanical tests per heat verify strength and toughness under sustained crushing loads.
Hardness Verification
Every concave liner is individually hardness tested to confirm 400 BHN performance.
UT Inspection
Ultrasonic testing per concave detects internal discontinuities, supported by photo evidence.
MPI Examination
Magnetic particle testing confirms surface integrity, with documented visual records.
Packaging & Shipping

Secure Export Packaging for Crusher Liners
Concave liners are packed using reinforced export-grade solutions, combining steel-supported pallets, anti-rust treatment, and internal protection to safeguard structure and machining surfaces during international transport.
Professional Global Mining Equipment Logistics
ZM INDUSTRY CO., LTD. manages global logistics for crusher parts through engineered loading plans, complete documentation, inspection coordination, and reliable international freight services, ensuring safe and timely delivery.
