| Abstract: | 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. |
