13-5-7 Is water-soluble phosphorus good at controlling moisture?

We produced 13-5-7 once. The raw materials were calcium chloride and ammonium chloride. We found that the moisture was difficult to control.

During production in our factory, it was found that the moisture content was high, the inlet and outlet temperature control was high, and the pellets felt very dry. However, analysis showed that the moisture content was high. The raw materials were 250 kg of calcium chloride and 520 kg of ammonium chloride. Could it be that calcium chloride reacted with ammonium chloride? Ask experts to analyze

It's not the free acid, it's probably the large amount of dihydrate gypsum in the calcium chloride.
