Types Of Decanters
horizontal and conveyor centrifuges. The principle behind a decanter centrifuge is based on the theory of gravitational
separation. For example, if you fill a vessel with a mixture of mud and water, over time the weight of the mud will cause it to settle down at the base of the vessel. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two.
Decanter 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.
Rotational Separation
The concept of rotational separation is similar to rides found at amusement parks and county fairgrounds. In these rides, placing yourself at an angle allows you to overcome the gravitational forces induced by rotation. Similarly, 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 slurry is brought into the centrifuge through an intake pipe and onto a conveyor.
* 2: Utilizing an internal feed compartment, the conveyor moves the slurry 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. The ability to purify a liquid makes
decanter centrifuges ideal for waste water treatment facilities. However, there are variety of industries for which such
centrifuges play an important role. Similar to other decanter equipment, centrifuges are simple to install and do not require a foundation to build upon. Their efficiency saves time and materials and is an essential component for many blue collar industries.

What is a Decanter Centrifuge?
50% (v/v) solids from liquids on a continuous basis. Typical industrial decanter applications include Crude Oil Tank Bottoms; Waste Oil; Industrial Wastewater; Sludge Dewatering; Fish Meal; WVO/UVO De-Sludging; Paint Sludge; Rendering etc. etc.
How does it work?
done using centrifugal forces that can be well beyond 3000 times greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid - the so-called pond - as required.
The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually "ploughed" out of the pond and up the conical "beach". The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl.
Horizontal Decanter Centrifuges Centrifuge World offers a wide variety of horizontal continuous cleaning decanter centrifuges which provide effective, low-maintenance solutions to continuous liquid clarifying and / or solids dewatering with advanced process and mechanical performance features.
Decanter centrifuges are extremely versatile and capable of adapting to varying throughput and process and material types. The machines are easy to adjust, require little operator attention, are relatively quiet and feature a small footprint.
Biodiesel Centrifuges: Centrifuge World offers a wide range of manual clean and self-cleaning biodiesel centrifuges process capacities ranging from 1 to 30-gpm.
Decanter Centrifuges Limitations:
* The decanter centrifuges cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.
* The machine can be very noisy and can cause vibration.
* The device has a high-energy consumption due to high G-forces.
* The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.
