Objectives of size reduction Size reduction leads to increase of surface area. Pharmaceutical capsules, insufflations ( powders inhaled directly into the lungs), suppositories and ointments require particles size to be below 60 mm size. To increase the therapeutic effectiveness of certain drugs by reducing the particle size. Size reduction produces particles in narrow size range.

REDUCTION Size reduction is the operation carried out for reducing the size of bigger particles into smaller one of desired shapes size with the help of external forces. Comminution is another term used for size reduction. The row materiel is generally present in the large size which cannot be used by the industries so, the materiel needs to be converted into smaller particle or powder.
