Mining & Quarry - Granite crusher - Mag impact crusher - Stationary equipment - Italy - +45% lifetime

Objective

Compare the wear performance of Creusabro^® Dual to 500HB water-quenched in a granite crushing application using a Mag’Impact crusher, with the goal of increasing wear life and reducing maintenance frequency in an extremely abrasive environment.

Test Conditions

• Location: Granite quarry in Modena, Italy

• Environment: High-speed impact crushing of hard granite aggregates, creating extreme abrasive wear on internal wear plates.

• Function: Internal protection plates in the Mag’Impact crusher, directly exposed to violent collisions with 0/50 mm granite fractions.

• Original material: 500 HB WQ, flame cut

• Replacement material: Creusabro® Dual, same dimensions and processing (flame cutting)

Results

• The Dillidur 500 plates achieved 241 hours of service life.

• The Creusabro® Dual plates lasted 324 hours, delivering a +45% improvement in wear life under identical conditions.

• No changes were required in fabrication or installation, ensuring a smooth transition.

Value Delivered

• +45% Wear Life Gain: Longer plate life significantly reduced downtime and replacement frequency.

• High-Abrasion Performance: Outstanding wear resistance in a granite environment, where only top-tier materials can perform.

• Reliable Integration: Flame cutting ensured dimensional accuracy and compatibility with existing crusher design.

• Lower Operating Costs: Fewer shutdowns and part replacements led to tangible savings over the production cycle.

Conclusion

By switching to Creusabro® Dual, Inerty Pederzona and Abraservice achieved a high-performance and cost-effective solution for protecting internal surfaces in Mag’Impact granite crushers — delivering a 45% increase in wear life without altering design or process.

Creusabro® Dual proves its strength in severe impact and abrasion applications, where it outperforms conventional 500 HB steels in real-world crushing operations.
