Northern Star Resources Limited, an Australian gold producer, sought improvements for their primary C125 Norberg jaw crusher to extend the life of fixed and swing liners. The current two-piece configuration caused premature wear on the middle wedges. Mining Wear Parts’ engineering team redesigned the crusher liners to a one-piece configuration, restricting unnecessary movement and upgraded the liners to heavy-duty Ceramic Metallic Inserts (CMI).
These changes resulted in a 71% increase in the life of fixed and swing jaws, providing an additional 5 weeks of usable wear life, increasing it from 7 to 12 weeks. The success of these improvements led the customer to request further assistance with liner developments for their HP6 crusher.Download PDF
