Abstract

Wet granulation involves the addition of a liquid binder to the feed powder. Capillary and viscous forces are responsible for the cohesion of granules in the wet state. In this work we investigate transition between capillary and viscous forces for pendular liquid bridges. Colloid probe atomic force microscopy is evaluated as a tool for investigating such phenomena at the nanoscale. A model describing the interparticle adhesive properties is developed.
