4. Capillarity: capillary pressure, force and rise
Interfacial tensions and wettability determine how well the granulating liquid spreads over the particle surface. To understand the mechanisms of granule formation, and to describe the intensity of the bonds formed, we need to look at capillary phenomena and their consequences: capillary pressure and suction. In wet granulation, these phenomena are involved from drop deformation through to granule formation, whether a binary agglomerate formed by a pendulum bridge or a wet granule formed by the wetting of a cluster of particles (figure 6 ).
4.1 Capillary pressure (or Laplace pressure)
Ever since Laplace's pioneering work was published in the early...
