Comparison of grinding characteristics in highpressure
Comminution in HPGR is a result of high inter-particle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous SAG mills.
HPGR High Pressure Grinding Rolls
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.
How HPGRs compare to conventional milling
Aug 20, 2019 Within comminution circuits, High Pressure Grinding Rolls HPGR are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40 less energy than traditional reduction methods, but their wearable
COMPARISON OF HPGR BALL MILL AND HPGR
In the past 20 years, the energy-efficient comminution technologies, including high pressure grinding rolls HPGR and high speed stirred mill, have been developed and adopted in the hard-rock mining operation in order to reduce the energy consumption and improve the process performance.

HRC Series high pressure grinding rolls HPGR Metso
High pressure grinding rolls HPGR are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

Mill Circuit Solution SAIMM
The pressure profile across the roll displays a tapering off of pressure toward the roll edges, leading to impaired comminution performance. The edge proportion is a function of the operating gap edge gap x 1.2, which is in turn a function of the roll diameter gap 22.5 of diameter, so a high aspect ratio design has a greater edge
