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 ...
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.
