Dense medium density adjusting system for coal dressing

Abstract

The invention discloses a dense medium density adjusting system for coal dressing, and belongs to the technical field of coal. The dense medium density adjusting system comprises a medium preparation system, a medium storage container, a medium mixing container and magnetic separation equipment, the medium preparation system comprises a guiding structure, a flushing mechanism and a containing groove, the guide structure comprises a containing area for containing a medium powder pile, the flushing mechanism flushes water to the medium powder pile in the guiding direction of the guiding structure, and the containing groove is formed in the end of the guiding structure in the guiding direction of the guiding structure. The inlet end of the magnetic separation equipment communicates with the containing groove through a first channel, the outlet end of the magnetic separation equipment communicates with the medium storage container, and the first channel is provided with a first control valve. The medium mixing container is communicated with the medium storage container through a second passage, and the second passage is provided with a second control valve; and the medium mixing container is communicated with the inlet end of the magnetic separation equipment through a third passage, and the third passage is provided with a third control valve. According to the technical scheme, manual medium storage and medium adding are not needed, the labor intensity is reduced, the medium returning function is added, and the suspension density and liquid level can be effectively reduced by combining water replenishing.

Description

Technical field [0001] Technical Field The present application belongs to the coal, in particular to a density PREPARATION conditioning system dense media. Background technique [0002] At present, heavy media separation coal preparation process has become the main mode, the main high-density magnetite powder, coal itself slime and water to form a density-suspension, suspension and appropriate density are sorting mixed coal fed sorter, floating suspension of lower density than coal, waste rock and the high density of the sink, and then using a separation technique to separate and discharge the coal and gangue. After Recommended discharged from the sorter carries a large number of suspension, the need for treatment sculping suspension so that the suspension to return to the barrel via engagement reuse. However, due to the coal itself to carry heavier quality, increase quality losses are inevitable, so the production process need to constantly add new media, in order to maintain th...
