Understanding The Dry Granulation Process Pill Presses

In wet granulation, powders are bound together using adhesives rather than compacting motion. As more liquid is added to the mix, bridges form between the particles, which increase the tensile strength of bonds. The process of wet granulation includes the massing of mix dry powders with granulating fluid.

Granulation Wikipedia

Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material.It is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use.
