Pressure GrindingRoll. High pressure grinding rolls (HPGR) SKD High pressure grinding rolls are an energy efficient grinding solution, and now SKD has improved this technology even further. The HRC, our innovative approach toHPGRtechnology, is like no otherHPGRon the market. Get Price

Interparticle comminution is theHPGRspecific grinding process in which material particles arecrushedand ground within the compressed material bed and not by contact with theroll surface. Feed material can be smaller than the gap, which is an important distinction as compared tocrushers, for example.

HPGRscan be usefully employed in brownfield projects to de-bottleneck conventionalcrushing/millingcircuits resulting in an increase in total plant capacity. “Furthermore, they can also be used as tertiary and/or quaternarycrushing stagesor in thepebble-crushing stageto improve downstream milling performance,” says TAKRAF.

Minerals Engineering 22 (6), 544–549), an approach was described to predict the specific energy of a range of tumbling mill andcrushing/high pressure grinding rolls (HPGR) circuits.

The Polycom can be specified as torolldiameter,rollwidth,rollspeed, hydraulic pressure and bearing size. Each model is designated byrolldiameter/rollwidth and frame size so, for example, a PC 17/12–4 has a 1.7-m-diameterrollthat is 1.2-m wide in a size 4 frame.
