Classification of centrifuges

A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Centrifuges are widely used in various sectors such as chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment, and shipbuilding.

The main principle of a filtration centrifuge is to use the centrifugal force generated by a high-speed rotating centrifugal drum (with appropriate filter materials) to accelerate the liquid phase in the solid-liquid mixture and throw it out of the drum, while keeping the solid phase inside the drum, achieving the effect of separating solids and liquids, or commonly known as dehydration.

The main principle of a settling centrifuge is the strong centrifugal force generated by the high-speed rotation of the rotor, which accelerates the settling speed of different specific gravity components (solid or liquid phase) in the mixed liquid, and separates substances with different settling coefficients and buoyancy densities in the sample.

Centrifuges are widely used in sectors such as mineral processing, coal, water treatment, and shipping.

The selection of a centrifuge should be based on the size and concentration of solid particles in the suspension (or emulsion), the density difference between the solid and liquid (or two liquids), the viscosity of the liquid, and the characteristics of the filter residue (or sediment).
