Agglomeration processes compact strength

Figure 5 The microlevel processes of compressive agglomeration, or compaction. These processes combined control compact strength, hardness, and porosity.

These processes complement spray drying, especially when larger particles are needed. Compaction results in a compressed product with low porosity, i.e. more strength. Agglomeration, in contrast, produces a fluffy powder with high porosity, ideally suited for applications that which call for instant dissolving.
