Hpgr Vs High Pressure Roller Mill

Comparison of grinding characteristics in highpressure

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 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

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

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
