Abstract:
1. A method for producing a particulate water-absorbing agent comprising: a polymerization step for polymerizing a monomer to obtain a polymer gel; a drying step for drying the polymer gel to obtain a particulate water-absorbing resin; a pulverization step for pulverizing the particulate water-absorbing resin; a classification step for sieving the particulate water-absorbing resin; a surface cross-linking step for cross-linking the neighborhood of the surface of the particulate water-absorbing resin to obtain a particulate water-absorbing agent; a packaging step for filling the particulate water-absorbing agent into a packaging material container for packaging; and a transportation step for transporting the products produced in each of the steps to the other steps; wherein at least any one of the steps including and subsequent to the drying step is in two or more lines for one line of the polymerization step, in which two or more units of the same apparatus are installed in parallel for one unit of a polymerization apparatus.
