General centrifuge classification

A centrifuge is a machine that uses centrifugal force to separate liquid and solid particles or components of a mixture of liquid and liquid. The centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or separate the two liquids of different density and incompatible liquid in the emulsion (for example, separating the cream from the milk); it can also be used to exclude Liquids in wet solids, such as wet clothes in washing machines; special ultra-speed tubular separators can also separate gas mixtures of different densities; use different density or granularity of solid particles to set different velocity in liquid, some sedimentation The centrifuge can also classify solid particles by density or particle size.

classification

According to the separation factor Fr value

Centrifuges can be divided into the following types:

1, constant speed centrifuge

Fr ≤ 3500 (generally 600 ~ 1200), this centrifuge has a lower rotation speed and a larger diameter.

2, high speed centrifuge

Fr = 3500 ~ 50000, the speed of this centrifuge is higher, the diameter of the drum is generally smaller, and the length is longer.

3. Ultra-high speed centrifuge

Fr>50000, because the rotation speed is very high (50000r/min or more), the drum is made into a slender tube type.

The separation factor Fr refers to the ratio of the centrifugal force of the material in the centrifugal force field to the gravity of the material in the gravity field.

By process use

Centrifuges can be divided into: filter centrifuges, decanter centrifuges.
