With the introduction of the high compression machines such as High Pressure Grinding Rolls (HPGR), Vertical Roller Mills (VRM) and Horomills, efficiency of the grinding circuits was improved in terms of energy and downstream effects. Among these devices, vertical roller mills have an important position in cement and mining industry. ...
HPGR consists of two counter-rotating rollers, i.e. a fixed roll and a floating roll. The hydraulic pressure system acts on a piston of the movable roller and makes it move towards the floating roll, applying high pressure for short durations on the material being crushed. ... The comparative performance of the HPGR-ball mill and HPGR-stirred ...
