摘　　要：空气重介质流化床干法选煤是适用于缺水地区煤炭加工的一种方法.阐述了流化床床高和密度对分选过程的影响和重要性,针对其特定的工艺特点提出利用PLC对空气重介质流化床叶轮给料器进行变频调速,使流化床床高和密度保持均匀、稳定.Air dense medium fluidized bed dry coal is suitable for coal processing in dry areas. The infuence and im- portance of height and density of fluidized bed height on sorting process is described. According to the technological features, it＇ s proposed that use of a specific PLC on the air dense medium fluidized bed impeller feeder for frequency control make the height and density of the fluidized bed height maintaining uniform and stable.
