First Graphene Limited provided results from field testing of PureGRAPH enhanced bucket wear liner trials. Rubber wear liners are an essential component on steel fabricated mining equipment, providing a resilient, sacrificial layer, which protects the steel equipment from abrasion wear during ore handling operations. The wear liners are replaced periodically and extending the periods between replacement is a critical need to maximise throughput at the mine. The bucket wear liners were installed at a major iron ore producer's load-out facility in the West Australia Pilbara region beginning in mid-2019. A standard wear liner and a graphene enhanced ArmourGRAPH wear liner ran simultaneously in the same location for the 62-week period. The ArmourGRAPH liners, manufactured by newGen Group, had been prepared using a low addition rate of PureGRAPH 20 in hot cast polyurethane (PU). The PureGRAPH enhanced liners were used side by side with standard PU liners throughout the 62-week trial before being returned to newGen Group for assessment. The liners as fitted in a reclaimer bucket after they were removed from service. An Elcometer 456 thickness gauge was used to determine the liner thickness at each point. The detailed abrasion analysis reported that the abrasion loss is significantly reduced in the PureGRAPH enhanced ArmourGRAPH liner, with a 6x reduction in average abrasion loss (improved resistance to wear). As abrasion loss is the primary mechanism of failure, a significant 6x increase in lifespan of the wear liner is anticipated. The abrasion analysis was performed on the rear sliding face of the bucket liner as this surface is well fitted to the steel bucket and provides the most representative analysis of liner wear life.
