Trelleborg Wear Liners Reduce Downtime, Down Under

Trelleborg’s engineered products operation in Australia has assisted in reducing unplanned downtime at the Tropicana Gold Mine, 330 kilometers east-northeast of Kalgoorlie, Australia, by improving the wear life of the High Pressure Grinding Rolls (HPGR) discharge pulping boxes. The high pressure grinding roll (HPGR) that handles wet composite for gold mining, was facing unacceptable shutdown rates due to the large amount of wear that was taking place on the discharge side of the two discharge pulping boxes. Engineering Consultant, Mintrex, was appointed to design a new box and called upon Trelleborg’s expertise to ensure that the lining and layout of the box would be robust and durable.
