Dense Medium Cyclone - Metallurgist & Mineral …

Dense medium cyclones are rapidly becoming a common choice for cleaning a much broader size range of raw coal than considered economically feasible just a few years ago. From a nominal top size of 63.5 mm to 76.2 mm down to 0.15 mm dense medium cyclones have been shown to be capable of operating economically and over a narrow range of efficiencies.
