PURPOSE: To uniformly cool the sintering material crosswise carried on the cooling machine by disposing partitions in the hood above the trough discharge end so as to demarcate the space above the sintering material carried on the trough into a plurality of sections, and disposing an air flow regulating damper at the top of the partitions as well as a thermometer in the sectioned space between the partitions.

CONSTITUTION: In a suction type sintering material cooling device, two to four partitions 7 are disposed in the upper hood 2 above the trough 5 to demarcate the upper hood into three to five sections crosswise. Further, a regulating damper 8 is disposed at the top of the partitions 7 to regulate the air delivery rate, and a thermometer 9 is disposed in the respective sectioned spaces 14 to measure the delivered air temperature. By controlling the regulating dampers 8 so that the measured delivered air temperature may be uniform crosswise, the cooling rate of the sintering material 6 in the trough can be made uniform crosswise.
