For the fluidized bed granulation the influence of process parameters on the material properties of the granules have been studied. A decreasing strength of the products with rising binder content in the injected liquid was found. On the other hand an increased binder content leads to a better granulation. Furthermore, it was shown that the retention time of the particles in the fluidized bed has an influence on the strength of the product, especially during the first minutes of fluidization. The moisture content of the granules in the case of this fluidized bed spray granulation seems to be negligible. In spite of different liquid injection rates, the moisture content of the particles was very dry (<< 1 mass-%).
