摘要:
An apparatus for manufacturing cement clinker is disclosed in which raw material powder of cement pre-heated by a pre-heating unit such as a suspension pre-heater and pre-calcined by a calciner is charged into a granulating furnace as to be granulated, thus-obtained granulated material is charged into a sintering furnace as to be sintered, and the sintered material is cooled and recovered by a cooling unit, the apparatus having a granulating furnace so that the granulating performance of the granulating furnace is improved. A fuel supply unit for forming a local hot region is disposed immediately above a porous perforated distributor disposed in the throat portion between the granulating furnace and the sintering furnace so that the granulating furnace is formed into a jet fluidized bed structure, the lower portion of the granulating furnace has an inverse frustum of circular cone (a cone portion) so formed as to cause the granulated material to form a downward moving bed, and raw material powder of cement is blown through the side wall of the cone portion, and it is sufficiently dispersed in the moving bed before it reaches the local hot region.
