comminution in hpgr is a result of high inter-particle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. the priority that hpgr can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous mills.the hpgr is the core equipment of the high pressure grinding process. the machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. this forces the rocks against each other and compresses the feeds density to 80% of its solid
hprm. other designations were also used for the high pressure grinding technology with respect to a wide range of applications from coarse crushing to very fine grind-ing, such as high pressure roller crusher, hprc. the ge neric term that has been widely settled upon is hpgr, high pressure grinding rolls, and is used in this paper as well.using a high-pressure roller mill in the process of the grinding system can increase the production efficiency of the entire system by 20% to 30%. At the same time, the total power consumption of the grinding system can be reduced by to 50% compared with the conventional grinding method.
