Abstract
The invention discloses a streaming assistant-selection jigging sorting method. A streaming device is additionally arranged in a bed layer so as to generate a local streaming area and streaming motion, a horizontally flowing water flow generates negative pressure in a tail flow area of a streaming motion plane, so that a part of relatively heavy sorted materials is gathered in the area, the horizontally flowing water flow generates a local loosing area in the tail flow area of the streaming motion plane, and accordingly local loose degree of the bed layer is improved. When the streaming assistant-selection jigging sorting method is used for sorting ores or coal, effects of improving sorting precision and a sorting lower limit can be obtained, water consumption is further reduced, processing quantity is increased, and the streaming assistant-selection jigging sorting method is brand-new and is particularly applicable to jigging sorting of high slack coal.
