High Pressure Grinding Roll Press Frame

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.

These are supported in the frame by spherical roll bearings, which are inherently self-aligning and very robust. In addition to radial loads, the bearings are able to accommodate axial loads acting in both directions, making them

High Pressure Grinding Rolls (HPGR) TENOVA

The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface.
