There is disclosed an improved, energy-saving granulation method, wherein use is made of a granulator (1) having a bottom floor (9) of a granulation section whose bottom is a perforated plate, an upper air feed pipe (23) for feeding air for fluidization to the bottom floor of the granulation section, a lower air feed pipe (2), air feed pipes (3, 4, 5) branched from the lower air feed pipe for jetting air into the granulation section, and jetting nozzles (6, 7, 8) provided at the centers of the air outlets for jetting a molten raw material; which comprises jetting a molten raw material from the jetting nozzles to approximately spherical nuclei in the granulation section, which have been fed after the particle diameter has been caused to be an average particle diameter of 0.4 to 3.0 mm, to form granules. There is also disclosed an improved granulator.
