Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in an emulsion (for example, separating cream from milk). It can also be used to remove liquid from wet solids, such as using a washing machine to dry wet clothes. Special ultra-fast tubular separators can also separate gas mixtures of different densities. Solid particles of different densities or particle sizes have different settling speeds in liquids. Some sedimentation centrifuges can also classify solid particles by density or particle size.
