ZGMn13 ZGMn13Cr2 ZGMn18Cr2 Cone Crusher Concave Fixed Cone Bowl Liner

1. Product Introduction

Cone Crusher Concave, also called Bowl Liner or Fixed Cone Liner, is a stationary wear-resistant casting installed inside the upper bowl assembly of cone crushers. It constitutes the fixed side of the crushing chamber and cooperates with the mantle. During operation, rocks and ores are squeezed, bent and sheared between concave and mantle to complete secondary and tertiary crushing.

Manufactured from high manganese steel ZGMn13, ZGMn13Cr2 and ZGMn18Cr2, the concave features prominent work-hardening performance. Its surface hardness rises continuously under impact load to deliver superior wear and impact resistance.

We customize cavity profiles, overall dimensions and flange structures according to customer drawings or crusher model numbers. Our concave serves as replacement spare parts for various cone crusher models, widely supplied to mining and quarry projects in Chile, Peru and other South American regions.

Key Advantages

• Work-hardening high manganese steel, great impact & abrasion resistance for longer service life
• Optimized crushing cavity design, stable product gradation and higher processing capacity
• Precision casting plus heat treatment, accurate dimensions for smooth assembly
• Optional coarse / medium / fine cavity types to satisfy different output particle requirements
• OEM & ODM available, complete documentation including MTC, MT and UT NDT inspection reports

Applicable Equipment

Single-cylinder hydraulic cone crusher, multi-cylinder hydraulic cone crusher, spring cone crusher

2. Application Scenarios

1. Metal Mineral Concentrators Secondary and tertiary crushing for copper, iron, gold, molybdenum, lead-zinc mines. Widely used in large South American mining projects.
2. Aggregate & Quarry Plant Medium and fine crushing of granite, basalt, limestone and river cobblestone for highway and concrete aggregate production.
3. Cement & Building Material Factory Limestone and clinker crushing under 24-hour continuous heavy-duty working conditions.
4. Metallurgical Solid Waste Recycling Crush steel slag, iron slag and mine tailings to realize solid waste resource recovery.
5. Non-metallic Minerals Crush quartz, feldspar, phosphate ore and fluorite, minimize over-crushing to guarantee downstream beneficiation efficiency.

Working Conditions Summary

• Secondary & tertiary hard rock crushing
• 24/7 continuous high-load mining operation
• Fixed cone wear liner replacement for cone crushers
• Strict requirements for finished particle shape and gradation

3. Inspection Procedure

1. Raw Material Inspection: Spectrometer test to analyze chemical composition of molten steel and verify alloy elements before pouring.
2. Casting Visual Inspection: Check surface defects including blowholes, shrinkage cavities, cracks and slag inclusions; remove risers and burrs.
3. Heat Treatment Inspection: Monitor heating and holding parameters; random hardness test (HB / HRC) to guarantee mechanical performance.
4. Dimension & Weight Inspection: Measure inner & outer diameter, height, taper, fitting surface dimensions against drawings; record single-piece weight deviation.
5. Non-Destructive Testing (NDT)
   • MT Magnetic Particle Testing: Detect surface and near-surface cracks
   • UT Ultrasonic Testing: Check internal shrinkage, porosity and inclusions inside castings
6. Final Sampling Inspection: Recheck appearance, dimension and hardness, compile full inspection documents.
7. Packing Inspection: Inspect seaworthy packing, mark part numbers and shipping marks before loading.

4. Certificates & Test Documents

1. Material Chemical Analysis Certificate
2. Mechanical Property Test Report (Hardness, Impact Toughness, Tensile Strength)
3. MT & UT NDT Certificate
4. Dimension & Weight Inspection Report
5. Mill Test Certificate (MTC), stamped by factory QC department
6. ISO9001 Quality Management System Certificate
