Compaction-granulation is a dry process that transforms powders into randomly shaped granules in a calibrated range (e.g. 0.2 to 0.8 mm, 0.4 to 1.2 mm, 2 to 4 mm, etc....). Usually no binder is required in this process and the bonding of the particles is only ensured by the mechanical pressure applied to the product to be compacted.
