Disc Stack Centrifuges
Disc Stack Centrifuges
With a clarifier or settling tank, particles and liquid phases, will fall to the bottom, but the lack of control and the length of time required makes natural settling unsuitable for modern industrial processes.
In essence, a disc stack centrifuge is a clarifier whose base is wrapped around a centre line. Rotating this unit rapidly means that the effect of gravity is replaced by a controllable centrifugal force – the effect of which can be more than 10 000 times greater than gravity on solids suspended in liquids.
When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers.
The disc stack
The key to good separation performance lies in the efficiency of the disc stack, the heart of the centrifuge, therefore the design of the disc is crucial. Alfa Laval has the expertise needed to match the demands involved in specific industrial processes.
Solids
Depending on the separation requirements disc stack centrifuges can handle solids in three different ways, from liquid/liquid separation (both 2-phase or 3-phase applications) to the separation of slurries having a solids content approaching 30% (normally 2-phase applications).

Alfa Laval disc stack centrifuges use a rapidly rotating bowl to separate suspended material from liquids and other phases. Rotation replaces gravity with controllable centrifugal force, which can exert more than 10,000 times gravity’s effect on solids. They suit modern industrial processes where natural settling takes too long, giving operators an alternative to a lengthy settling stage.
- Denser particles move outward against the rotating bowl wall
- Less dense liquid forms concentric layers inside the solids
- Liquid/liquid separation supports two-phase or three-phase applications
- Slurries can have solids content approaching 30%
- Disc stack design is crucial to separation performance
