摘要： A sintering method of cement clinkers in which preheated cement raw material powder is granulated and sintered in a fluidized bed granulating and sintering furnace, and granulated and sintered clinkers are introduced into a cooling device, for manufacturing high-quality cement clinkers by use of a single fluidized bed granulating and sintering furnace efficiently with a small heat loss, wherein clinkers are discharged from the fluidized bed granulating and sintering furnace (14) through a clinker dropping hole (26) which is provided in a fluidizing gas distributor (22) of the furnace (14) or in a radial direction extending from the gas distributor (22), an opening area of the clinker dropping hole (26) is regulated by a gate portion (34) to maintain the differential pressure in a fluidized bed (18) within a predetermined range, air for classifying and cooling the clinkers is blown into a discharge chute (28) connected to the clinker dropping hole (26), the amount of the blown air is regulated to make the flow velocity of the air blowing from the clinker dropping hole (26) different from the flow velocity of air flowing through nozzles of the gas distributor (22), and the clinkers are introduced into a cooling device (16) through a hermetic discharge device (30) provided below the classifying and cooling air intake position.
