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.
Dry comminution technologies, such as High Pressure Grinding Rolls HPGR and Vertical Roller Mills VRM, have been successfully used in other industries such as cement and coal for decades, and ...
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
