Abstract
The present invention is to provide a shredder for super absorbent polymer that includes: an inlet portion for feeding a plate-shaped super absorbent polymer; a pulverizing portion for pulverizing the super absorbent polymer fed through the inlet portion; and an outlet portion for discharging the pulverized super absorbent polymer from the pulverizing portion. The pulverizing portion includes: a rotary drum to which a plurality of rotary blades are attached; at least fixed blade for pulverizing the super absorbent polymer in cooperation with the plural rotary blades; and a housing for holding the rotary drum and the at least one fixed blade. Each rotary blade has a shape of polygon with at least one vertex having an acute angle of at most 45 degree. The present invention is also to provide a preparation method for super absorbent polymer using the shredder for super absorbent polymer.
