Research on broad-scale dry coal screening and deep separation system at power coal preparation plant
Coal screening and separation equipment plays a decisive role in coal quality control in the coal industry.The characteristics of raw coal and the slurry properties of coal and gangue were studied and analyzed,the performances of flip-flow screen and intelligent jigging separator were comprehensively analyzed by various methods,including vibration testing process,particle size analysis,density analysis,screening,separation efficiency evaluation.The research results showed that processing capacity had a significant impact on screening efficiency,with a significant decrease in screening efficiency as processing capacity increased.In addition,it was found that there was clean coal in the first stage of gangue in the research of intelligent jigging separator,so it was necessary to further optimize the intelligent algorithm of the jigging separator.Optimizing screening parameters and separation effects is particularly important for meeting the demand for high-quality coal products of the coal industry,and has practical application significance for improving coal screening efficiency and quality control.
