Transcript

  • 1. Granulation
    • 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
  • 2. 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
  • 3. Granulation
    • Wet granulation equipment
      • 3 main types
        • shear granulators
        • high speed mixer/granulators
        • fluidized bed granulators
      • shear granulator
  • 4. Wet Granulation
      • high speed mixer/granulator
  • 5. Wet Granulation fluidized bed granulator
  • 6. Wet Granulation
      • other more specialized granulators
        • spray driers
  • 7. Wet Granulation
      • pelletizers
  • 8. Dry Granulation
    • Dry granulation equipment
      • sluggers
      • roller compactors
