PURPOSE:To provide a rotary type circular cooler for high-temp. granular materials such as sintered ore mixed with coarse and fine grains which is simple in construction, is small in size and capable of making efficient cooling by specifying the charging of the sieved coarse and fine grain sizes and providing partition walls in a cooling chamber. CONSTITUTION:The crushed high-temp. sintered ore is sieved by a screen 3 and is charged into the cooling chamber 2 formed between an outside peripheral wall 6b provided to the circumferential part on the top surface of a rotary table 11 and the inside peripheral wall 6a provided apart therefrom at a desired spacing. The high-temp. sintered ore is cooled by a gas 7 introduced through the wall 6a and the cooled sintered ore is fed from the bottom end on the outside of the wall 6b. The coarse and fine grain sintered ores 14, 15 sieved therein are respectively supplied to the chambers between the partition wall 20 and the wall 6b and between the wall 20 and the wall 6a. Mixing both ores with each other is prevented by the wall 20. The gas 7 flowing therein has the diffluent ratio corresponding to the difference in the packing density between the coarse grains 14 and the fine grains 15. The diffluent ratio can be adjusted simply by adjusting the grain size segments of the coarse grain part and the fine grain part.
