The capacity of an HPGR circuit, as distinct from the unit capacity discussed above, is obviously a function of the circuit design. Of the above variables, the feed bottom size is particularly relevant in this regard, as a truncated feed necessarily implies the pres- ence of a screen or other classification device upstream of the HPGR.
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

HPGR—FAQ large roll diameter, smaller width—whereas KHD have traditionally preferred a low aspect ratio and Köppern a 'square' ratio. More recently, KHD have offered higher ratios for certain large capacity applications. Polysius and Köppern use self-aligning spherical roller bearings, whereas KHD use cylindrical roller bearings.
HPGR product the improved grindability will result in significant cost savings for energy and from reduced labour and maintenance around fewer operating ball mills. This is especially advantageous in operation where power is a costly item, or where it is necessary to maintain the plant capacity where harder or leaner ores are encountered.
