| description | The invention relates to a process for producing superabsorbent polymer particles, comprising surface postcrosslinking, classifying the surface postcrosslinked superabsorbent polymer particles, deagglomerating the separated oversize fraction using a roll crusher and recycling the disintegrated oversize fraction before or into the classification of the surface postcrosslinked superabsorbent polymer particles.
L'invention concerne un procédé de production de particules polymères superabsorbantes, comprenant la post-réticulation de surface, la classification des particules polymères superabsorbantes post-réticulées en surface, la désagglomération de la fraction surdimensionnée séparée à l'aide d'un broyeur à cylindres, et le recyclage de la fraction surdimensionnée désintégrée avant ou lors de la classification des particules polymères superabsorbantes post-réticulées en surface. |
