摘要：The present invention is directed to a method and apparatus for separating coalfrom impurities, which comprises a first and second tank including drag conveyor meansand agitation means for the combination of saturating a raw mass containing coal andimpurities, dispersing the impurities in to water, separating the coal from the impuritiesand flowing the mass from the front of the tanks to the rear of the tanks. A crusher asarranged between the tanks through conveyor means for transferring the mass betweenfrom one tank to the crusher and from the crusher to the other tank. The mass from thesecond tank is conveyed in to a separator pan which includes a separator plate, theseparator plate having a configuration and being located within the separator pan at aposition, so that an upper flow portion of the mass having a lower specific gravity passesthereover, and so that a lower flow portion of the mass having a higher specific gravitypasses thereunder and out a hole in the bottom of the separator. A collector bin islocated at an output flow end of the separator pan for collecting coal particles from theupper flow portion of the mass flowing over the separator.
