Sep 05, 2019· Optimise yourpebble crushingwithHPGR High Pressure Grinding Rollsoffer an energy-efficient way tocrushpebbles and alleviate bottlenecks caused by mills struggling to reduce the stubborn particles of hard ore.
Roll Surface WearofHPGR Crusher Increasing roll speed increases turbulencein the feed material and slip of feed against theroll surfaces, leading to elevated wear rates. This should generally be a concern only at the top end of the practical speed range.
In conventionalcrushing, a gap setting in the above size range would not result in an effective size reduction of material finer than this setting.HPGR’s can generally accept a coarse feed size up to about 90 mm, provided therolldiameter is sufficiently large (Rylatt and Popplewell, 1999, Morley, 2003, Ntsele and Sauermann, 2007). As a ...

High-pressure grinding rolls (HPGRs) have struggled for acceptance into the hard-rock mining sector. CRITICALHPGRPARAMETERSHPGR rolldiameters typically range from 0.5 m to 2.8 m, depending on the supplies, androllwidths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer. TypicalHPGR…
