this way. • Crystallization of dissolved substances: when the granules dry, crystallisation of this material takes place and the dissolved substance acts as a hardening binder. Any material in the granulating liquid will function in the manner, e.g. lactose incorporated into powder blends granulated with water. The size of the crystals produced in the bridge will be in influenced by the rate of drying of the granules; the slower the drying time, the larger the particle size. Therefore, it is…
