<P>PROBLEM TO BE SOLVED: To provide a rotation type cooling device for dry cooling, small and excellent in cooling operation, and allowing maintenance of a severely damaged inlet part to be easily carried out in a short time for increasing operation rate. Ž<P>SOLUTION: In the cylinder rotation type cooling device to which granular or massive material to be processed is input at high temperature, a cooling drum which cylinder-rotates includes an internal watering pipe for spraying cooling water to the inside to such an extent that the water can be evaporated, as well as an air jet pipe for introducing cooling air to the inside, and a watering device for cooling inside via the drum by watering the cooling water outside. An exhaust gas outlet port and a cooled material outlet port of the cooling drum are respectively provided with temperature sensors to detect exhaust gas temperature at the outlet port and/or cooled material temperature at the outlet port. The cooling device includes a control device by a computer for adjusting a spraying amount by the internal watering pipe based on the detection. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
