Abstract

See full text

A process for producing superabsorbent particles by polymerizing a monomer solution or suspension, comprising drying of the resultant aqueous polymer gel in an air circulation belt drier, grinding, classifying, and optionally thermal surface postcrosslinking, wherein the aqueous polymer gel is introduced into the air circulation belt drier by means of an oscillating conveyor belt, the underside of the revolving conveyor belt is freed of adhering polymer gel by means of at least one stripper device, and the underside of the revolving conveyor belt is sprayed with water.
