Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing a super absorbent polymer, comprising: preparing a monomer composition including an aqueous ethylene-based unsaturated monomer, and a polymerization initiator; supplying the monomer composition to a polymerization reactor including a conveyer belt and applying UV radiation or heat onto the supplied monomer composition on the conveyer belt to prepare a plate-shaped super absorbent polymer; supplying the polymerized plate-shape…
