High Pressure Grinding Roll Technology

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.

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.

High Pressure Grinding Rolls (HPGR) is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. Read more SGS comminution experts have developed a simple testing methodology to avoid some of the difficulties associated with using HPGR.
