What is a Centrifuge

Solid Liquid Separator December 9, 2024 Centrifuge

A machine that uses centrifugal force to separate or concentrate non-homogeneous liquid-phase mixtures is called a centrifuge.

In industries such as chemical engineering, petroleum, metallurgy, and pharmaceuticals, it is often necessary to separate non-homogeneous liquid-phase mixtures (liquid-liquid, liquid-solid, or liquid-liquid-solid) that occur during production processes to obtain the desired products or intermediates.

This separation process can be achieved through methods such as gravity settling, gravity filtration, vacuum or pressure filtration, centrifugal settling, and centrifugal filtration.

Both centrifugal settling and centrifugal filtration utilize centrifugal force to achieve separation. In a centrifugal force field, conditions differ significantly from those under gravity. Compared to other separation methods, centrifugal separation offers the following advantages:

High Separation Efficiency: Centrifugal force is generated by the rotation of the material's mass. With a fixed rotation radius, higher speeds produce greater centrifugal force. This makes it possible to efficiently separate even extremely small particles or materials with higher viscosity.
Adjustable Force: The magnitude of the centrifugal force can be adjusted by varying the rotational speed, allowing for tailored separation for different materials.
