Objectives of size reduction Size reduction leads to increase of surface area. Pharmaceutical capsules, insufflations (i.e. 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.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Jul 01, 2015 Media milling can be considered a modernized version of the ball mill . This technology, first developed by Liversidge and co-workers [76] , [77] , is a classical wet milling technique wherein a sufficiently concentrated dispersion of drug particles in an aqueous or non-aqueous liquid medium is subjected to a traditional ball milling operation ...
Milling is a powerful unit operation to aid in the control of particle size for a variety of processing, bioavailability, reactivity, and safety‐related drivers.
