Presentation 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
