It’s really helpful to the industry to have their ores tested in our large HPGR before replacing their rod or ball mills,” said Rao. “We’re able to determine if the ore is amenable to high pressure roll crushing, identify the mineral composition, and test a variety of pressures and roll speeds. Third party testing is very important.”
