Mines & Quarry - Jaw crusher - Side plates in primary crushing - Sweden - +48% lifetime

Objective

Evaluate the performance of Creusabro^® 8000 as a replacement for 450 HB wear steel in jaw crusher side plates, with the goal of improving wear life efficiency (T/mm), reducing maintenance, and maximizing the use of steel volume under severe crushing conditions.

Test Conditions

• Location: Primary crushing site in Sweden

• Environment: High-impact and abrasive wear during the continuous crushing of large stone blocks (171,882 tonnes processed), placing significant stress on the jaw crusher’s side plates.

• Function: Side wear plates in a primary jaw crusher, responsible for protecting structural components from direct rock impact and friction.

• Original material: 450 HB, 40 mm thickness

• Replacement material: Creusabro® 8000, 40 mm thickness, processed by flame cutting and machining

Results

• The 450 HB plates delivered a wear efficiency of 4,297 tonnes per mm of plate thickness.

• The Creusabro® 8000 plates achieved 6,366 T/mm, representing a +48% improvement in material efficiency.

• Both materials were installed at 40 mm, making the comparison fully representative under identical conditions.

Value Delivered

• +48% Wear Efficiency (T/mm): Significantly more material processed per mm of plate thickness.

• Maximized Steel Usage: Homogeneous wear resistance across the full thickness of Creusabro® 8000 allowed for better value from each plate.

• Reduced Interventions: Longer wear life delayed maintenance shutdowns and reduced labor costs.

• Easy Processing: Standard flame cutting and machining ensured compatibility with existing manufacturing procedures.

Expert Insight

This case highlights the importance of evaluating wear materials not just by total lifetime, but by efficiency per millimeter (T/mm). Creusabro® 8000’s uniform hardness and wear resistance throughout the plate allow for full utilization of the steel, making it the optimal choice in high-load crushing environments where every mm counts.

Conclusion

By upgrading to Creusabro® 8000, KEWAB and Bergsmekaniska achieved a +48% gain in wear efficiency (T/mm) in jaw crusher side plates — extending performance without changing part design or process.

Creusabro® 8000 confirms its leadership in primary crushing applications, where material toughness and consistent wear resistance are essential.
