Abstract: Granules are concentrated in a side stream of the water used during granulation (for cooling and cutter lubrication). This side stream forms the conveying medium for the granules. Preferred features: The side stream of granulation water contains 15-35 wt%, preferably 15-25 wt% of granules. Separation between granulator (C) and storage location exceeds 200 m, preferably exceeding 500 m. Drying of granules takes place in the immediate vicinity of further treatment and/or storage. Side stream temperature after leaving the separator (D) is raised, especially through 5-40 deg K. Vertical relationships between: granulator, side stream handling plant (G), and if appropriate, the drying unit (H), facilitate granule conveying to further processing and/or storage.
