The present invention is a method for producing super absorbent particles by polymerizing a monomer solution, wherein the monomer solution is continuously polymerized on a continuous belt of a belt reactor, the obtained polymer gel is masticated, and the polymer gel obtained on the bottom of the belt reactor Rinsing the polymer gel with water into the separation unit, separating the polymer gel from the water in the separation unit and recycling the polymer gel to a mastic, wherein the polymer gel has a swelling capacity in water of at least 100 g/g, and the polymer in rinse water The residence time of the gel is less than 40 minutes, and the separation unit has an opening with a perforated width of at least 1 mm. |
