摘要： When fly ash is added to a cement kiln to materialize it after being desalinated by washing, scale is prevented from growing in a dissolution reaction apparatus depositing calcium-containing compounds dissolved in slurry, and the fly ash is effectively used as a cement material. A dissolution reaction apparatus according to the invention comprises: a dissolution tub 3 for dissolving powder material, a wet dust collector 5 for collecting powder material and mist while reacting slurry S in the dissolution tub 3 with gas G and returning the collected powder material and mist to the dissolution tub 3. A second wet dust collector 7 can be provided for collecting powder material and the like accompanying to the gas G discharged from the wet dust collector 5, and both the wet dust collectors 5, 7 can be vertical type and mounted independently with each other on the dissolution tub 3. The slurry S and the gas G can react with each other with parallel flow by feeding the slurry S and the gas G to an upper portion of the first wet dust collector 5, or the powder material and the like accompanying to the gas G may be collected with counter flow by feeding the gas G discharged from the dissolution tub 3 to a lower portion of the second wet dust collector 7.

摘要： To provide a cement manufacturing apparatus and the like capable of increasing quantity of fly ash used in the apparatus while controlling unburned carbon content in cement within a permissible range. The cement manufacturing apparatus and the like comprises a removal means for removing unburned carbon from gypsum, and a grinding means for grinding gypsum from which unburned carbon is removed by the removal means together with clinker to generate cement. With the apparatus, total unburned carbon content in cement can be reduced, and the quantity of fly ash used in the apparatus can be increased by the reduced amount of unburned carbon. The removal means can remove unburned carbon contained in gypsum as well as unburned carbon contained in fly ash, and the grinding means may grind the fly ash from which unburned carbon is removed together with the gypsum, from which unburned carbon is removed, and clinker. The removal means may simultaneously remove unburned carbon contained in gypsum and unburned carbon contained in fly ash.
