Abstract
A process for pneumatic delivery of water-absorbing polymer particles, the compressor used for pneumatic delivery having a steep characteristic and the initial gas rate in the delivery corresponding to a Froude number of from 10 to 18.
Claims12
A process for pneumatic delivery of water-absorbing polymer particles, wherein a volume flow rate of a compressor used for the pneumatic delivery falls by less than 50% when a pressure rises from no-load operation to 800 mbar and an initial gas rate in the delivery corresponds to a Froude number of from 10 to 18.
