Conquering Extreme Conditions in Chilean Copper Mine: XX Teeth Achieve 35% Longer Life in Continuous Blasting Operation

Codelco's El Teniente mine, one of the world's largest underground copper mines. Working face rock hardness reaches Mohs 7-8, with continuous large-scale blasting operations causing severe impact wear on bucket teeth.

• Impact Fatigue: Over 200 high-intensity impacts daily
• Thermal Cracking: High-temperature rock contact post-blasting reduces material performance
• Compound Wear: Hard rock cutting + abrasive wear dual degradation
  Previous teeth average replacement cycle: 5-7 working days

Phase 1: Material Revolution

• Patent "Dual-Phase Wear-Resistant Alloy Technology"
• Surface hardness HB550-600
• Core maintains impact toughness ≥120J

Phase 2: Engineering Optimization

• 3D Scanning Modeling for Caterpillar 6040 hydraulic shovel
• Reinforced Tooth Base Design increases bending strength by 30%
• Self-Cleaning Tooth Profile reduces material adhesion loss

"In El Teniente's extreme conditions, XX teeth performance has been impressive. We have included this project in our 2024 Standard Procurement List, with estimated annual maintenance savings of $180,000." — Codelco Procurement Director

Based on this project's success, we have developed:

• "Blasting Conditions Special Series" - For metal mines
• "Deep Mine High-Temperature Version" - For mines below 1000m
• "Smart Wear Monitoring System" - Real-time replacement alerts
