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.Get Price

Dry grinding has been utilised in the cement industry for many years for comminution of limestone, slag and clinker, firstly through ball and rod mills, and in recent decades using high pressure
pressure is released. An example of Airflex clutch service life is given by one mill superintendent, who gives his Airflex VC grinding mill clutch major credit for a 4 percent annual production increase. He eliminated onceamonth repairs on a 600 hp synchronous motor because the Airflex principle permits modulated power transmission.
