Decanter Centrifuge Principles

A decanter centrifuge employs the same principles of gravitational force. However, unlike the glass mixture, the process is expedited through the use of continuous rotation. In fact, rotation provides anywhere from 1000 to 4000 times the normal gravitational force, reducing the time required for separation from hours to seconds.

 A decanter centrifuge is essentially a bowl tube that rotates at an extremely high speed. The bowl tube is equipped with an internal conveyor which moves in the same direction but at a different velocity.

How the Decanter Process Works:

1: The sample is brought into the centrifuge through an intake pipe and onto a conveyor.

2: Utilizing an internal feed compartment, the conveyor moves the sample through a nozzle into the bowl.

3: The bowl rotates at high speeds to induce centrifugal forces.

4: High speed rotation separates the solid material from the liquid in a matter of seconds.

5: The conveyor delivers the solid material upwards where it is discharged through a nozzle.

6: The solid material removed, the purified liquid is released from a separate output.

Features

1. Simple to install and do not require a foundation to build upon.
2. Their efficiency saves time and materials and is an essential component for many blue collar industries
3. With less wearing parts
4. Can be placed outdoors
5. Drier solid after separation
6. Suitable for sample with much solid
7. Automatical discharging

Application

There are variety of industries for which such centrifuges play an important role. The ability to purify a liquid makes decanter centrifuges ideal for many process.

1. Waste water treatment facilities, for example municipal sewage, industrial effluents, biogas slurry,
2. Fruit juice & pulp, vegetable juice clarification after press or fermentation
3. Animal blood dehydration
4. DDGS (Distillers Dried grains with soluble), Distillery Stillage. Lees dehydration
5. Humic acid
6. Fish meal, fish meat
7. Kitchen waste, hogwash process
8. Starch treatment/classification/dehydration (solid-liquid separation)
9. Soy Protein separation/dewatering
10. Kaolin, graphite classification/dehydration
11. Dyes, pigments classification/dehydration
12. Coal tar dehydration
13. fecal or manure treatment
14. Clarfication of many kinds of oil
15. Antibiotics
16. Chemical Intermediates
