Background

Centrifuges are machines that utilize centrifugal force to separate components of a liquid from solid particles or a mixture of liquid and liquid. The centrifugal machine is mainly used for separating solid particles from liquid in suspension or separating two liquids which are different in density and are mutually insoluble in the emulsion; it can also be used to remove liquids from wet solids, such as drying wet clothing with a washing machine; the special overspeed tube separator can also separate gas mixtures with different densities; by utilizing the characteristic that the sedimentation speeds of solid particles with different densities or particle sizes in liquid are different, some sedimentation centrifuges can also classify the solid particles according to the densities or particle sizes.
