Abstract:
A water-absorbent resin particulate sieving process comprising the steps of:a) selecting water-absorbent resin particulates, with said water-absorbent resin particulates being at a temperature between 40 and 100.degree. C.;b) supplying a sieving device of which the temperature is maintained at or above a temperature lower than the temperature of said water-absorbent resin particulates by 20.degree. C.; andc) sieving the water-absorbent resin particulates with the mesh of the sieving device, with the step of sieving the water-absorbent resin particulates being conducted while the temperature of the sieving device is maintained at or above a temperature lower than the temperature of said water-absorbent resin particulates by 20.degree. C.
