Centrifuge types, classification particle size

Centrifuges are used for the classification of particles in size ranges below 10 /im. Two types are used solid bowl centrifuges, usually with a cylindrical, conical bowl, rotated about a horizontal axis and nozzle bowl machines, fitted with discs. 

Centrifugation uses centrifugal force to separate particles on the basis of their size or density, to separate immiscible liquids of different densities, filter a suspension or break down an emulsion and colloidal suspension, or to separate isotopes. Centrifuges can be classified into two types ones which utilize filtration and ones that use sedimentation for separation. Theoretical analysis changes depending on the type of classification.
