Sieving is called the main process, in which powders are divided according to which sieves they go through. Cyclone separation and air separation use centrifugal forces to different particles depending on size and density. Elutriation suspends particles inside of a moving fluid to individual fractions based upon particle density and size.
In this presentation viewers will capable to study liquids for external use like liniments and lotions, liquids for oral cavity for example mouthwash, throat paints and gargles.
