PDF First choice for HPGR technology and service

High pressure grinding is achieved by an advanced type of grinding roll. Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls. This particle bed is created between two choke-fed, counter-rotating rolls.

High pressure grinding rolls (HPGR) - Metso Outotec

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.

PDF 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 = 2-2.5% of diameter), so a high aspect ratio design has a greater edge

First choice for HPGR technology and service

A High Pressure Grinding Roll produces a particle size distribution (PSD) that is wider, with more fines, than a tertiary crusher (e.g. cone crusher) would produce. The reason is that the compressive force not only acts on the coarse end of the PSD, but throughout the particle bed on both coarse and fine particles,
