A disc stack centrifuge separator 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 two liquids.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.
The disk centrifuges separators with self-cleaning bowl are equipped with a stack
of conical disks to create a large equivalent clarification area within a relatively
small bowl volume. These separators are likewise available as versions for
clarification and separation.
Centrifuges separators with self-cleaning bowl are able to periodically discharge the separated
solids at full speed. For this purpose, several ports are spaced evenly around the bowl periphery.
These ports are opened and closed by means of a movable sliding piston located in the bowl
bottom. The opening mechanism is actuated hydraulically. Water is normally used as a control
medium; in special cases, low-viscous organic fluids can also be used.
This opening mechanism enables both partial ejections and total ejections. Total ejections involve
discharging the entire contents of the bowl with closed feed valve. In the case of a partial ejection,
by contrast, only part of the bowl contents is ejected with open feed valve.
