  • Method for Producing Water-Absorbing Polymer Particles
    Publication number: 20120048973
    Abstract: A process for producing water-absorbing polymer particles, wherein an aqueous polymer gel is applied by means of a swivel belt to the conveyor belt of a forced-air belt drier, and the swivel belt, proceeding from one end position, is accelerated through a first pivot angle to an angular speed v1, decelerated through a second pivot angle to an angular speed v2 and decelerated through a third pivot angle to the other end position.
    Type: Application
