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 ...
