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.
