There is also disclosed a granulation method, comprising monitoring the pressure difference by the above method, stopping the feed of a liquid of a molten raw material to the air feed pipe whose pressure difference is abnormal, and compensating the amount corresponding to the stoppage with the remaining function. The detection method is a method capable of detecting accurately a malfunction related to jetting of air in the granulation of urea or the like. Further, the granulation method is a granulation method wherein, accurately, in response to the occurrence of a malfunction related to the jetting of air, the feed of a raw material liquid to the malfunctioned section is stopped, and the raw material liquid to be fed to the jet nozzles having other normal air outlets is suitably increased, thereby allowing continuous operation, with the productivity before the occurrence of the malfunction kept.
