Built for LKAB's Underground Iron Mine: XX Tooth Achieves 40% Longer Service Life Breakthrough

LKAB of Sweden, a world-leading underground iron ore producer, faces extremely hard and abrasive magnetite ore at its Kiruna mine. The customer's previous bucket teeth had an average service life of only 120 hours under continuous loading, resulting in frequent replacements, increased equipment downtime, and significantly impacted production efficiency and overall costs.

Through joint on-site inspection by our engineers and technical team, we provided a customized solution:

• Material Upgrade: Implemented "Super Alloy Steel" to enhance surface hardness and core toughness.

• Structural Optimization: Redesigned the tooth tip angle and wing plate structure to optimize stress distribution and reduce fracture risk caused by stress concentration.

• Precise Compatibility: Provided a full tooth series customization for their Liebherr R 9200 loaders, ensuring seamless installation and optimal performance matching.

After 6 months of on-site tracking, data comparison showed significant improvements:

• Life Leap: Average service life per set extended to 168 hours, a 40% increase.

• Efficiency Gain: Reduced replacement frequency led to a 15% improvement in overall equipment utilization.

• Cost Reduction: Despite a 10% higher unit price, the cost of wear parts per ton of ore mined decreased by 22%, with estimated annual savings for the customer exceeding €120,000.

• Customer Testimonial: "The durability of XX teeth exceeded our expectations. It's not just the product; their professional preliminary analysis and rapid technical response created real value for us." — LKAB Kiruna Site Equipment Manager
