摘要： There is disclosed a method for detecting clogging of air feed pipes, comprising air feed pipes (15), each having an outlet (13) for jetting air into a granulation section (1), and jetting nozzles (13), each situated at the center of the air outlet of a said air feed pipe for jetting a liquid of a molten raw material (e.g. molten urea), wherein, in jetting the liquid of the molten raw material from the jetting nozzles into the granulation section to carry out granulation,(a) an orifice section (14) is provided at a lower part of each of the air feed pipes (15), a section for taking up orifice rear pressure (16) is provided in each air feed pipe and is located downstream of the orifice section, and a section for taking up orifice forward pressure (17) is provided upstream of the orifice section, and(b) the pressure difference between the orifice forward pressure and the orifice rear pressure is measured, to detect clogging of the air feed pipes based on an abnormality in the pressure difference regarding the air feed pipes. 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.

摘要： 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 involves the steps of 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.
