High Pressure Grinding Mill Performance Feature: 01- Compared with the traditional mills, its capacity increases by 10%-20% under the same power condition, and compression force of rollers to material improve 800-1200kgf under the force of high-pressure spring. 02- Output Size of final product can be 0.613mm (30mesh) –0.033mm (425mesh).

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.
