[0002] like Figure 1 The working principle of the FL-120 fluidized bed granulator in the prior art is shown as follows: the airflow D is filtered by the air filter 1 under the negative pressure of the fan 10, heated by the heater 2, and enters the fluidized bed granulation chamber (raw material container) 4 from the first airflow distribution plate 13 through the air supply duct 14, agitating and suspending the powder contained in the fluidized bed granulation chamber 4 into a fluidized state, and mixing occurs. The adhesive liquid C is sent to the nozzle 8 from the second pipeline 6, atomizing the liquid material into fine droplets, wetting the powder material, and making it stick together for granulation. The hot air flow dries it at the same time, and the ungranulated powder is captured by the capture bag 9. When a certain amount is reached, the exhaust valve 11 is closed, the capture bag in the left chamber of the filter chamber shakes, and the shaken powder falls into the fluidized bed granulation chamber and mixes and bonds with the materials therein, and the capture bag in the right chamber of the filter chamber shakes.
