The iron ores to be supplied to the second pelletizer 18 are sifted out by a mesh in the range of 0.5-10 mm, the iron ores under a sieve are crushed, size-regulated and turned to the raw material of the granulated substances P, and the iron ores on the sieve are supplied to the first pelletizer 12 together with remaining iron ores not to be supplied to the second pelletizer 18. For the iron ores under the sieve which are crushed and size-regulated, 90 mass% or more of them are under 500 μm and 80 mass% or more of them are under 22 μm, and they are pelletized under the presence of moisture further.

Thereby, the decomposition of crystal water is suppressed and further inhibited because the drying temperature is controlled to be ≥40 and ≤250°C. Further, the breakdown and degradation of the pellets can be suppressed and further prevented.
