Abstract

The present invention relates to a method for producing a superabsorbent polymer, and more specifically, to a method for producing a superabsorbent polymer, which uses a specific component of an inorganic substance in a fine powder regranulation process to improve drying efficiency during the production process, thereby realizing excellent absorption-related physical properties of the produced superabsorbent polymer.
