SIZE SEPARATION - PHARMA NOTES

Mar 24, 2021  SIZE SEPARATION. 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.
