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.
The wear parts within our High Pressure Grinding Roll are long-lasting, but also very easy to replace when they do wear down. Up to 20-30% reduced energy consumption Energy efficiency is key to running a profitable operation, so saving 20 to 30% could pay huge dividends.

ABB presents the well-known drive solutions for ball and SAG mills, which are gearless mill drives and dual pinion drives. Furthermore, ABB displays its capabilities in developing systems for demanding drive applications such as drives for high pressure grinding rolls, long belt conveyers and downhill conveyors.
To make the mill more efficient some roll mills are equipped with a system allowing to guarantee a high pressure (10-50 bar) in between the rolls. It is also mandatory for these mills to have a spring system allowing to release the pressure if the constraint is too important ( foreign body for example) and avoid mechanical damages.
