摘　　要：空气重介流化床干法选煤是选煤工艺的一次改革，其工艺关键在干流化床床高及密度的均匀和稳定。本文简要介绍了空气重介流化床干法选煤的工作原理和控制机理、介绍了流化床床高和密度的在线测控方法。The dry coal separator with air dense medium fluidized bed is a reform of preparation technology, and the crux of this technology is that the density and height of the fluidized bed are uniform and stable. The paper briefly introduces the operating principle and control mechanism of the separator, and discusses the online monitoring method for the density and height of the bed.
