Abstract: The invention relates to a process for producing water-absorbing polymer particles, comprising the steps of: • - processing an aqueous polymer gel from polymerization of a monomer solution or suspension, • - drying the aqueous polymer gel in a conveyer dryer, in particular in a forced air conveyer dryer, wherein • - the conveyer dryer has a circulating conveyer belt and the aqueous polymer gel is conveyed on the circulating conveyer belt, and wherein • - the circulating conveyer belt is formed as a circulating plate conveyer belt, comprising a number of belt plates separated by a hinge line of a hinge assembly and each belt plate having a surface for receiving the aqueous polymer gel, wherein said hinge assembly comprises a knuckle joint (301) with the hinge line in form of a straight hinge line.
