The invention relates to a process for producing superabsorbent polymer particles, comprising storing acrylic acid in at least one tank (B) at a production site for acrylic acid and in at least one tank (B) at a production site for superabsorbent polymer particles, wherein the at least one tank (B) at the production site for acrylic acid and the at least one tank (B) at the production site for superabsorbent polymer particles are interconnected by one single pipe line () and the flow inside the pipe line () is temporary reversed during interruptions of the production superabsorbent polymer particles.

Process for producing superabsorbents

The invention relates to a process for producing water-absorbing polymer particles, comprising polymerization, drying the resulting polymer gel on a through circulation belt dryer, crushing the dried polymer gel, pre-grinding, separating of incompletely dried particles with a perforated plate, grinding and classifying the resulting polymer particles.

Process for producing water-absorbing polymer particles

The invention relates to a process for producing water-absorbing polymer particles, comprising thermal postcrosslinking in a contact dryer having external heated outer surfaces.
