A centrifuge is a device, which employs a high rotational speed to separate components of different densities. This becomes relevant
in the majority of industrial jobs where solids, liquids and gases are merged into a single mixture and the separation of these
different phases is necessary.
A decanter centrifuge separates solid materials from liquids in slurry and therefore plays an important role in wastewater treatment,
chemical, oil and food processing industries.
Operating principle of a decanter centrifuge
The operating principle of a decanter centrifuge is based on gravitational separation. Naturally, a component with a higher density
would fall to the bottom of a mixture, while the less dense component would be suspended above it. A decanter centrifuge increases
the rate of settling through the use of continuous rotation, producing a gravitational force between 1000 to 4000 times that of
normal gravitational force. This reduces the settling time of the components by a large magnitude, whereby mixtures previously having
to take hours to settle can be settled in a matter of seconds using a decanter centrifuge. This form of separation enables more rapid
and controllable results.
Performance features of decanter centrifuge
Coming in a range of sizes, horizontal continuous cleaning decanter centrifuges provide an effective, low maintenance solution to
liquid clarifying and solids dewatering with advanced process and mechanical performance features.
