What are the risks faced by our client due to their worn jaw crusher?
- Loss of efficiency/productivity during crushing
- Increase in unplanned maintenance operations
- Significant and repetitive repair costs
- Compromised safety for employees working nearby
- Higher electricity consumption as the machine exerts more force
One of our experts visited the site to study the wear phenomena and the type of jaw crusher to be made more reliable.
Our client was using a standard 450 HB anti-abrasion steel with a thickness of 40 mm. However, the wear caused by this type of equipment was so significant that it was no longer sufficient.
Produr, therefore, proposed a solution with Creusabro® 8000 anti-abrasion steel. This steel has a unique metallurgical composition (enriched with Chrome, Nickel, Molybdenum) and a specific heat treatment (oil quenching).
Its wear resistance is 40 to 50% higher than conventional 500 HB steels.
It is particularly resistant in cases of extreme wear with violent impacts, such as in jaw crushers (or even in linings for hoppers, chutes, screens, etc.).
Based on existing dimensions, Produr constructed side crusher linings using Creusabro® 8000, and the results observed at our client’s site are astonishing
