Overview:

A filter centrifuge is a centrifuge that uses centrifugal filtration to separate components from a suspension.

The filter centrifuge drum is equipped with numerous holes in its wall, and the inner surface of the rotor is covered with a filtering medium. When the suspension is introduced into the drum, it rotates along with the drum, generating tremendous centrifugal pressure. Under this pressure, the liquid phase in the suspension flows through the filtering medium and exits via the holes in the drum wall, while the solid particles are retained on the surface of the filtering medium, thereby achieving separation of solids from liquids. The centrifugal force generated in the drum is hundreds or even thousands of times greater than gravity, which significantly enhances the filtration process, accelerates the filtration rate, and produces filter cakes with lower moisture content.

Suspensions with solid particles larger than 0.01 millimeters can generally be filtered using a filter centrifuge.

Our country is currently developing a new-generation, cost-effective centrifuge.
