A disc stack centrifuge separates solids and one or two liquid phases from each other in one single continuous process, using extremely high centrifugal forces.
When the denser solids are subjected to such forces, they are forced outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers.
The area where these two different liquid phases meet is called the interface position. This can be easily varied in order to ensure that the separation takes place with maximum efficiency.
Inserting special plates (the disc stack) provides additional surface settling area, which contributes to speeding up the separation process dramatically. It is the particular configuration, shape and design of
these plates that make it possible for a disc stack centrifuge to undertake the continuous separation of a wide range of different solids from either one or
The concentrated solids phase formed by the particles can be removed continuously, intermittently or manually, depending on centrifuge type and the amount of solids involved in the specific application.
