CRUSHING APPARATUS FOR A SUPERABSORBENT POLYMER, AND METHOD FOR PRODUCING A SUPERABSORBENT POLYMER USING SAME

WIPO Patent Application WO/2011/149313

A2

The present invention relates to a crushing apparatus for a superabsorbent polymer, comprising: an inlet unit through which a plate-type superabsorbent polymer is fed; a crushing unit which crushes the superabsorbent polymer fed through the inlet unit; and a discharge unit which discharges the superabsorbent polymer crushed by the crushing unit. The crushing unit includes: a rotating drum on which a plurality of rotating blades are attached; one or more fixed blades which cooperate with the plurality of rotating blades to crush the superabsorbent polymer; and a housing in which the rotating drum and one or more fixed blades are arranged. The present invention also relates to a method for producing a superabsorbent polymer using the above-described crushing apparatus for a superabsorbent polymer.
