Patent ID: 8329844

Claim:
A process for producing water-absorbing polymer particles by polymerizing a monomer solution or suspension comprising a) at least one ethylenically unsaturated monomer which bears acid groups and may be at least partly neutralized, b) at least one crosslinker, c) at least one initiator, d) optionally one or more ethylenically unsaturated monomer copolymerizable with the monomer specified under a), and e) optionally one or more water-soluble polymer in at least one polymerization reactor, a resulting polymer gel being removed from the polymerization reactor, optionally comminuted, stored intermediately in at least one delay vessel in the form of a particulate polymer gel, removed by means of at least one first conveying device at a lower end of the delay vessel and dried, wherein the intermediately stored particulate polymer gel is conveyed within the delay vessel by means of at least one second conveying device above the first conveying device in the direction of the first conveying device.
