摘要： PURPOSE:To produce granules efficiently without remelt-sticking by solidifying a high-temp. melt by cooling in a tank of an inverted circular cone shape while ejecting a gas of a specific velocity from the lower and upper parts of the tank. CONSTITUTION:In the stage of granulating a high-temp. melt such as molten slag and solidifying the same by cooling, a tank 21 of an inverted circular cone shape having a small opening in the bottom part and a large opening in the upper part is used and a gas is ejected at such a velocity that the velocity is higher than the suspending velocities of particles in the lower part of the tank 21 and attains roughly the min. fluidizing velocities for particles in the upper part of the tank 21. Then, even with compact hardware, treating capacity is high, and the high temp. melt is granulated and solidified by cooling with virtually no remelt-sticking among the particles.
