Abstract

The subject invention provides water-absorbent resin agglomerates having high strength and superior absorbency, and a method of producing water-absorbent resin agglomerates which can prevent agglomerateion of hydrated water-absorbent resin, allowing the resin agglomerates to be efficiently dried and cured. A method of producing water-absorbent resin agglomerates according to the present invention comprises the steps of: (a) mixing first water-absorbent resin particles and an aqueous soluteion so as to produce a hydrated water-absorbent resin; and (b) mixing the hydrated water-absorbent resin with second water-absorbent resin particles or fine particles.
