| titleOfInvention | Method for producing water absorbent resin particles |
| abstract | A method for producing water-absorbing resin particles containing granulated particles, wherein the amount of aqueous liquid relative to fine polymer powder is small (for example, the total mass of the portion of fine polymer powder excluding water and the aqueous liquid). To provide a method for obtaining water-absorbing resin particles having excellent water-absorbing performance even when the content is 10 to 45% by mass based on the total amount of water. A method for producing water absorbent resin particles containing granulated particles is disclosed. In the method, a mixture is formed by mixing polymer fine powder and an aqueous liquid containing water and having a temperature of 0° C. or higher and lower than 40° C., and the mixture is kneaded to agglomerate the polymer fine powder. obtaining dried agglomerates by removing at least part of the water from the agglomerates; and pulverizing the dried agglomerates to form granulated particles. include. In this method, the amount of the aqueous liquid to be mixed with the fine polymer powder is 10 to 45% by mass based on the total mass of the portion of the fine polymer powder excluding water and the aqueous liquid.
