By simply reversing the oil flow, the hydraulic cylinders can be used to retract the rolls and allow the tramp to fall through, getting the machine back online quickly. Oil-cooled bearings The HPGR has a skid mounted tank with a lubrication oil conditioning system that supplies clean filtered and temperature conditioned oil to the roll bearings.
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.
