Abstract
A belt drier arrangement for drying an aqueous polymer gel and for comminuting the dried polymer gel to give dried polymer particles, having: a belt drier having a drier setup and a conveyor belt for receiving and for drying the aqueous polymer gel to give a dry cake or fragments on a receiving surface of the conveyor belt, and a comminution arrangement, disposed downstream of the drier setup in product flow direction, for comminution of the dried polymer gel of the dry cake or fragments to give dried comminuted polymer particles. The comminution arrangement has a comminutor in the form of a milling drum which is disposed with an upper working line of a working edge of the milling drum at the level of or above a receiving surface of a conveyor belt, for mill processing of the dry cake or of the fragments, where the milling drum is designed to eject comminuted dried polymer particles of the dry cake or of the fragments in the downward direction.
