A method for producing urea granules having low moisture absorption capacity, with a urea granulator, having a granule flow inlet side and oppositely a granule flow outlet side, forming an axis alongside which granules from a urea solution and a urea/ammonium salt-stream are formed, whereby the solution and the salt-stream are sprayed as a mixture or separately via a feed system unit via various nozzles into the granulator onto a seed material. In this process the highest amount of the salt-stream is sprayed into the granulator at the granule flow inlet side and the amount of the salt-stream is decreased alongside the axis of the granulator from the granule flow inlet side to the granule flow outlet side. |
