    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 = 2–2.5 of diameter) so a high aspect ratio design has a greater edge

  • Comparison of grinding characteristics in high-pressure

    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.

    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.
