HPGR High Pressure Grinding Rolls | Weir
With their excellent throughput capacity, low maintenance requirements and energy efficiency, high pressure grinding rolls are fast becoming a goto for greenfield projects looking to maintain their margins despite commodity price pressures and declining ore grades On average, comminution is responsible for 25% of the final energy consumption of an average mine site13/7/2016· By adding a Polycom highpressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneouslyHPGR High Pressure Grinding Rolls
High pressure grinding rolls (HPGR) minevik Outotec
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 minevik Outotec's high pressure grindingHigh Pressure Grinding Rolls •HPGRs compress and grind the particle bed in the operating gap between two counterrotating rolls •The floating roll is pressed towards the fixed roll to maintain a working gap and pressure set point •Increasing the operating pressure will increase the kWh/tHIGH PRESSURE GRINDING ROLL ceecthefuture
