Wet granulation is subjected to powders having poor flowability and insufficient ability to bond between particles. In both cases, binding solutions are added to the mass, improving the adhesion between the particles. Granulation, or wiping of the wet mass, is carried out in order to compact the powder and obtain uniform grains — granules with good flowability. Wet granulation includes successive stages: grinding of substances into a fine powder and mixing of dry medicinal substance with auxiliary substances; mixing of powders with granulating liquids; granulation; drying of wet granules; powdering of dry granules. Grinding and mixing is carried out in mills and mixers of various designs presented earlier. The resulting powder is sifted through a sieve.
