<P>PROBLEM TO BE SOLVED: To provide an apparatus for producing a colored granular material, which can easily produce the colored granular material whose granule diameter is nearly uniform. <P>SOLUTION: The apparatus has a mixing machine 2 to mix a coating material C containing a glass frit and a core granule B, a firing machine 4 to fire the mixture of the coating material C and the core granule B to fuse the coating material C on the surface of the core granule B to thereby form a colored layer T on the surface of the core granule B, a cooling machine 5 to cool the core granule B having the colored layer T, and further a drying machine 3 to dry the mixture before the firing. The drying machine 3 can reduce moisture content contained in the mixture of the coating material C and the core granule B, and provides a state in which a large number of the core granules B is hardly fired in a lump state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
