Effect of high-pressure grinding rolls pretreatment on the
The diameter of roller was 250 mm and the length was 120 mm. By operating the hydraulic transmission system, the roller pressure was kept constant at 25.2 kN, 31.5 kN and 37.8 kN respectively. Correspondingly, the pressure intensity on the cross section of the roller could reach 0.8 Mpa, 1.0 Mpa and 1.2Mpa respectively.High Pressure Roller Mills are used in the cases of medium-fine crushing of hard materials such as ceramics, minerals from 5 up to 9 on the MOHS hardness scale, metals and metal alloys.

A time dynamic model of a high pressure grinding rolls crusher
The crusher was then retrofitted with hydraulic cylinders to increase the pressure between the rollers. This was the predecessor to the high-pressure grinding rolls (HPGR) crusher, which became popular in Europe for applications in the cement industry. The introduction of the HPGR in minerals processing sparked at the beginning of the 2000s.Hybrid Comminution with High‐Pressure Roller and Stirred Bead Milling. Yanmin Wang E. Forssberg. Materials Science. 2005.
