Fine coal beneficiation: comparison study of the separation efficiency of a dense medium cyclone and flat-bottom cyclone
Near-gravity material (NGM) is the fraction of coal particles with a relative density within a range of ± 0.1 of the relative density of the separating medium during coal washing. High levels of NGM in coal impede classifier separation efficiency because NGM particles have low settling rates, which …
