Abstract: The invention relates to a method for producing water-absorbing polymer particles, wherein an aqueous polymer gel is applied to the conveyor belt of a circulating air belt dryer by means of a slewing belt conveyor, and the slewing belt conveyor is accelerated starting from an end position over a first slew angle to an angular velocity v
1 , decelerated over a second slew angle to an angular velocity v
2 , and decelerated to the other end position over a third slew angle.-

Abstract: Surface-crosslinked superabsorbents are produced using a process that comprises the steps of contacting a superabsorbent base polymer with a polyvalent metal salt solution produced by dissolving at least two different polyvalent metal salts, at least one of which comprises a chelate-forming anion, and heat-treating to produce a surface-crosslinked superabsorbent.
