METHOD FOR PRODUCING SUPERABSORBENT PARTICLES

摘要

The invention relates to a method for producing superabsorbent particles by polymerisation of a monomer solution or suspension, comprising the steps of drying the obtained aqueous polymer gel in a circulating-air belt dryer, grinding, classification, and optionally thermal surface post-cross-linking, wherein the aqueous polymer gel is introduced into the circulating-air belt dryer by means of an oscillating conveyor belt, and deflector elements are provided on the edges of the conveyor belt.
