  1. Granulation • Is done to: • improve flow properties of the mix • improve compression properties of the mix • prevent segregation of components in powder mix • reduce production of toxic dust • reduce possibility of ‘cake’ formation • increase convenience of transport CHEE 440

  2. Wet Granulation • particle bonding mechanisms • adhesion and cohesion forces in immobile liquid films • interfacial forces in mobile liquid films • solid bridges • attractive forces between solid particles CHEE 440

  3. Wet Granulation • Wet granulation equipment: • high shear granulator CHEE 440

  4. Wet Granulation • low shear granulator

  5. Wet Granulation fluidized bed granulator CHEE 440

  6. Wet Granulation • spray granulation CHEE 440
