high pressure grinding rolls have a length to diameter ratio of 0.5.this provides the following advantages: large roll diameters allow the feeding of lumpy ores,minimised wear costs;thick roll tyres permit refurbishment of the roll bodies,self-aligning roller bearings dimensioned for a 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
applied the high pressure crushing mechanism, the machine will have the higher crushing efficiency, lager crushing ratio and wider adaptability. To adjust the clearance of roll surface automatically, so it can keep the crushing force constancy and makes the better grain shape and more fine granularity.hpgrs (high pressure grinding rolls, also known as roller at a high specific pressure of 4..0 nmm and the quartz impact crusher, to avoid introduction of high crusher ,quarry plant,quarry crusher ,stone crusher ,grinding mill
