To provide a method of producing ferric phosphate and a byproduct fertilizer using ammonium phosphate.SOLUTION: A byproduct fertilizer production granulator used in the method, comprises a housing comprising a storage space. The storage space of the housing is successively divided into a granulation chamber, a screening chamber and a material storage chamber from top to bottom. A blow assembly is provided between the granulation chamber and the screening chamber. A vibration screen reciprocally movable in the vertical direction is provided between the screening chamber and the material storage chamber. A material discharge pipe is connected to the material storage chamber. A top cap is detachably attached on the upper end of the housing. A plurality of sprayers are provided on the top cap to spray a molten material into the housing. An exhaust pipe is connected to the top cap. The blow assembly includes mutually connected distribution pipes arranged in a zigzag shape. A plurality of air-ducts are connected to the upper end of the distribution pipes. An air introduction pipe is connected to one side of a distribution pipe.SELECTED DRAWING: Figure 1 【課題】リン酸アンモニウムを用いてリン酸第二鉄および副産物肥料を調製する方法を提供する。【解決手段】本方法に用いる副産物肥料生産用造粒装置は、収容空間を有するハウジングを備え、前記ハウジングの収容空間は、上から下へ造粒室、篩い室および材料貯蔵室に順次仕切られ、前記造粒室と篩い室間にブローアセンブリが設けられ、前記篩い室と材料貯蔵室間に垂直に往復変位可能な振動篩が設けられ、前記材料貯蔵室に材料排出管が接続され、前記ハウジングの上端にトップキャップが着脱可能に設けられ、前記トップキャップに前記ハウジング内に溶融材料を噴霧するための多数の材料噴霧装置が設けられ、前記トップキャップに排気管が接続され、前記ブローアセンブリは千鳥状に配列されて相互に接続された分配管を含み、前記分配管の上端に多数の送風管が接続され、前記分配管の一側に空気導入管が接続される。【選択図】図１
