1. a method of making super absorbent resin comprises the step sizing mode of utilizing, wherein:

  • The concentration that contains acidic group monomeric water-soluble unsaturated monomer and unsaturated monomer solution of neutralization ratio in 45 to 85 moles of % scopes is carried out polymerization in the scope of 20 to 55 weight parts, the water gel of reaction back gained, cut into the following body that coagulates of particle diameter 20mm with 100 ℃

    of warm air dryings to 180 ℃

    of scopes of temperature, pulverizing, screening is to utilize the rotational circle cartridge type mesh screen machine with at least one rotary vane arrangement to be screened super absorbent resin in advance.
