Mining & Quarry - Crusher - Interlinings - Stationary equipment - Sweden - +200% lifetime

Objective

Compare the wear performance of Creusabro^® 8000 to 450 HB water-quenched steel in crusher interlinings, with the aim of improving wear life and reducing the frequency of part turning or replacement — all while using thinner material.

Test Conditions

• Location: Aggregate and gravel production facility in Sweden

• Environment: Heavy abrasive wear from continuous crushing of stone, with repeated contact between the interlining and processed material.

• Function: Crusher interlining plates that protect the machine structure and require regular turning or replacement as they wear.

• Original material: 450 HB water-quenched steel, 8 mm thickness

• Replacement material: Creusabro® 8000, 6 mm thickness, processed by plasma cutting.

Results

• With 450 HB steel (8 mm), the interlining had to be turned or replaced twice to process 200,000 tonnes.

• With Creusabro® 8000 (6 mm), the same part was turned six times, processing 600,000 tonnes before replacement — a 200% increase in wear life.

• The thinner Creusabro® plate delivered triple the material throughput, confirming its superior wear resistance and full-thickness efficiency.

Value Delivered

• +200% Wear Life Gain: Extended use between turning/replacement operations tripled material processed.

• Reduced Thickness, Increased Performance: 6 mm Creusabro® 8000 outperformed 8 mm 450 HB — demonstrating superior efficiency per mm.

• Fewer Maintenance Interruptions: Less frequent handling and replacement operations reduced downtime and labor cost.

• Optimized Steel Usage: Better performance with less material means more sustainable and cost-effective operations.

Expert Insight

This case demonstrates the power of wear efficiency per mm. Thanks to its homogeneous and toughened microstructure, Creusabro® 8000 provides full-thickness wear resistance — allowing thickness reduction without compromising durability. In fact, the thinner plate outperformed a thicker standard steel by a wide margin.

Conclusion

By switching to Creusabro® 8000, LedinsGrus AB and Bergsmekaniska implemented a high-performance, lighter, and longer-lasting solution for their crusher interlinings — achieving a 200% increase in service life and processing three times more material.

Creusabro® once again proves to be the smart choice for high-abrasion applications in the aggregates industry.
