How HPGRs compare to conventional milling
Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. This makes HPGRs more flexible when it comes to meeting ...

"In recent years, the trend to smaller top-size ore feed into SAG mills has been matched by a trend toward smaller but more balls in the SAG mill charge. High ball-to-rock ratios and low overall mill charge levels are now widely used. These practices can result in periodic loss of rock charge and ball-on-liner damage," said Royston.
