PROBLEM TO BE SOLVED: To provide a production method that makes it possible to obtain a granule with excellent strength, excellent flowability, and a reduced occurrence of impalpable powder.SOLUTION: A method for producing a granule has the following steps 1 and 2, where an organic acid content is 30 mass% or more and 70 mass% or less, and the ratio of the organic acid relative to a nonionic surfactant is 5 or more and 25 or less. Step 1: the organic acid and the nonionic surfactant are mixed. Step 2: the mixture obtained by step 1 is mixed with water-soluble binder and the mixture is granulated, to obtain a granule.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】強度に優れ、流動性が良く、微粉の発生の少ない造粒物が得られる製造方法を提供する。【解決手段】下記工程1及び2を有し、有機酸の含有量が30質量%以上70質量%以下であり、非イオン界面活性剤に対する有機酸の割合が5以上25以下である造粒物の製造方法。工程1:有機酸と非イオン界面活性剤とを混合する工程工程2:工程1で得られた混合物に水溶性バインダーを混合し、混合物を造粒し、造粒物を得る工程【選択図】なし
