Micronizing Apparatus for Hydrogel of Super Absorbent Polymer

A micronizing apparatus for hydrogel of super absorbent polymer comprising:

• a body supplied with hydrogel or reassembled hydrogel through a hopper formed at one side, and having a transfer space formed inside of the body configured for transferring the supplied hydrogel to the other side;
• a first rotation shaft rotatably disposed in the transfer space, and having a screw formed on an outer circumferential surface so as to transfer the hydrogel from the one side to the other side;
• a pre-cutter fixedly installed to the body at the other side of the screw, and having a plurality of pre-cutter holes through which the hydrogel transferred by the screw may pass;
• a first cutter rotatably disposed at the other side of the pre-cutter in the body, and connected to the first rotation shaft so as to be able to rotate together with the first rotation shaft and primarily cut the hydrogel having passed through the pre-cutter holes;
• a first hole plate fixedly installed to the body at the other side of the first cutter, and having a plurality of first through-holes through which the hydrogel primarily cut by the first cutter may pass;
• a second rotation shaft co-axially disposed with the first rotation shaft, and disposed so as to be rotatable independently from the first rotation shaft;
• a second cutter rotatably disposed at the other side of the first hole plate in the body, and connected to the second rotation shaft so as to be able to rotate together with the second rotation shaft and secondarily cut the hydrogel having passed through the first through-holes;
• and
• a second hole plate fixedly installed to the body at the other side of the second cutter, and having a plurality of second through-holes through which the hydrogel secondarily cut by the second cutter may pass.
