ABSTRACT:
The present invention provides a granulation method with increased drying effect while assuring the pressure for spraying the aqueous solution and the necessary number of nozzles equivalent to those of conventional design. Specifically, the granulation method uses a granulator structured by a fluid bed which fluidizes the granulating-particles, an air feed pipe to introduce air, a nozzle for spraying the raw material aqueous solution being located at center part of the air feed pipe, and a perforated plate to feed a fluidization air to the fluid bed, thus granulating the raw material aqueous solution by spraying thereof from the nozzle into a granulation part, wherein a multi-nozzle in a specified shape having a plurality of nozzle ends thereon is used as the nozzle for spraying the raw material aqueous solution.
