Aggregate - Plant crushing - Hammer chopper - Rotation 80 rpm - Stationary equipment - Switzerland - +36% lifetime

Objective

Evaluate the performance of Creusabro^® 4800 compared to standard 400 HB water-quenched steel in a low-speed crushing application, with the goal of increasing wear life while maintaining ease of processing.

Test Conditions

• Location: Environmental processing plant in Switzerland

• Environment: Low-speed crushing (80 rpm) of mixed materials including earth, clay, and pebbles, generating moderate but highly repetitive abrasive wear.

• Function: Hammer chopper component used in a crushing plant, exposed to continuous abrasion under rotation.

• Original material: 400 HB water-quenched steel

• Replacement material: Creusabro® 4800, processed by laser cutting.

Results

• The Creusabro® 4800 component reached 82 hours of service life, compared to 60 hours with the original 400 HB steel — a 36% increase.

• The switch to Creusabro® 4800 was seamless, with laser cutting ensuring precise geometry and rapid production turnaround.

Value Delivered

• Extended Wear Life: +36% longer service life reduced maintenance frequency and improved component reliability.

• Consistent Performance: Maintained wear resistance in a steady, repetitive abrasion environment with moderate rotational speed.

• Quick Implementation: Laser cutting enabled high precision and compatibility with the existing design.

• Cost & Time Savings: Fewer changeovers and lower operational disruption led to improved plant efficiency.

Conclusion

By selecting Creusabro® 4800, Blöchinger and Abraservice implemented a more reliable and efficient wear solution, achieving a 36% increase in service life for hammer chopper components in a green processing application.
