- This process not only solves the tasks, but also the services and to increase the capacities of the spray towers while maintaining the same energy requirements (performance increases of 20% and above are possible) and at others to ensure the processability of highly concentrated slurries (Concentration by 10% and more possible compared to the prior art), but in the case of spray drying of tripolyphoshate-containing ones Granules also achieve a higher degree of phosphate conservation.
- This can be explained, for example, by reducing the Slurry viscosities can also lower the tower inlet temperatures (lower energy consumption), which causes the decomposition of the tripolyphosphate is pushed back. This in turn has the consequence that the increased Conservation level lower amounts of phosphates are used can without suffering a loss in primary washing performance.
- Another major advantage is the increase in Bulk density of the spray-dried granules, resulting in further compaction measures (e.g. compacting granulation) essentially become unnecessary. This has the advantage of being uniform, free-flowing heavy, yet low-dust granules are obtained.

Das Schüttgewicht der sprühgetrockneten Granulate betrug 769 g/l.
- M4/3:
- Es wurden 2 Gew.-%, bezogen auf das sprühgetrocknete Granulat, Natriumgluconat im Austausch gegen Natriumcarbonat eingesetzt. Die Slurrykonzentration betrug jedoch jetzt 75,9 Gew.-%, die Viskosität unter Betriebsbedingungen 12000 mPas. Das Schüttgewicht der sprühgetrockneten Granulate betrug 762 g/l.
- M4/4:
- Es wurden 3 Gew.-%, bezogen auf das sprühgetrocknete Granulat, Natriumgluconat im Austausch gegen Natriumcarbonat eingesetzt.Die Slurrykonzentration betrug wie in M4/3 75,9 Gew.-%, die Viskosität unter Betriebsbedingungen jedoch nur 10000 mPas. Das Schüttgewicht der sprühgetrockneten Granulate betrug 749 g/l.
