Size Seperation (Pharmaceutics) |authorSTREAM

Dec 29, 2016Definition Size separation is a unit operation that involves the separation of a mixture of various size particles into two or more portions by means of screening surfaces. Size separation is also known as sieving, sifting, screening. This technique is based on physical differences b/w the particles such as size, shape and density.

Size separation equipment in which particles move in a fluid stream is now considered, noting that most of the plant utilises the difference in the terminal falling velocities of the particles: However, in the hydraulic jig, the particles are allowed to settle for only very brief periods at a time, and this equipment may therefore be used when the size range of the material is large.
