Abstract
An apparatus for sintering cement clinker with a spouted fluidized bed granulating furnace and a fluidized bed sintering furnace is provided which includes a perforated distributor having a multiplicity of nozzle holes through which gas for granulating injected raw material for cement while spouting and fluidizing the same is introduced; a dropping port through which granulated raw material for cement is discharged and which is disposed to face a spouted fluidized bed, wherein classifying gas is introduced through the dropping port at a classifying flow velocity which is selected to be different from a flow velocity of gas to be introduced through the multiplicity of nozzle holes into the spouted fluidized bed granulating furnace, and means is provided therein to discharge the granulated raw material for cement while classifying the same by using the effect of the classifying gas which is introduced through the dropping port; and an injection chute for injecting the granulated raw material for cement from the dropping port to the fluidized bed sintering furnace.
