To provide a cooling and solidifying device for bused slag in which the processing capacity is large, cooled slag is readily separated, and even when the fused slag including salts is processed, no problems occur, such as hindrance in the operation of the device, lowering of the quality of discharged solidified slag.
The device comprises two cylindrical rotors 10a, 10b which are constituted so as to exert cooling. One of the rotors, the rotor 10a, is provided with guide flanges 11a, 11b at both ends thereof, respectively. The other rotor 10b is inserted between the flanges 11a, 11b with its ends being in contact with the flanges. The two rotors 10a, 10b are horizontally located while being in contact with each other at their peripheral surfaces. Each of the rotors is constituted so that it is rotated upward direction from the portion that has been in contact with the peripheral surface of the other rotor, and that the number of revolution can be controlled. The diameter of the flange 11b is smaller than that of the flange 11a.
