摘　　要：分析了空气重介质流化床选矿方法与其他传统选煤方法在保持密度稳定性方面的差异。空气重介质流化床选煤技术分选精度高、投资少、无环境污染、分密度调节范围宽 ,该技术在 <6mm细粒级振动流化床、三产品双密度层流化床、>5 0 mm大块煤深床型流化床及The paper discusses the difference between coal dry beneficiation with air dense medium fluidized bed and other traditional separations in keeping density stability. Air dense medium fluidized bed dry beneficiation of coal is of high precision, low investment, no environmental pollution and wide density regulation. The great progresses of the technology have been made at lab, such as the vibrated fluidized bed of 6～0 mm, three product double density fluidized bed, deep fluidized bed of >50 mm and triboelectric cleaning of <1 mm.
