Industrial Centrifuge | Types, Applications, Cost & Benefits

What is an Industrial Centrifuge?

An industrial centrifuge is a powerful separation machine that utilizes centrifugal force to effectively separate solids from liquids. Its centrifugal force is thousands of times stronger than that of gravity, making it an efficient tool for separation.

This factor results in the instant division of solids and liquids. Furthermore, for dissimilar liquids with varying densities, it also divides the fluids.

Imagine an industrial centrifuge as a larger version of a lab centrifuge, with a flow-through design and increased scale.

The centrifuge continuously ejects both the solid and liquid components that have been separated.

Types of Industrial Centrifuges

Industrial centrifuges are divided into two primary categories: Filtration and Sedimentation.

Filtration Type

Filtration-Centrifuge

A perforated screen in a filtration centrifuge allows fluid to exit while retaining solids. The separated liquid is collected in the bowl casing and drains out.

The optimal rotational speed (in terms of centrifugal force) for filtration centrifuges is relatively low.

These products excel at dividing significant quantities of large, solid particles from liquids. An instance of this could involve separating sugar crystals from syrup or a chemical precipitate from the supernatant solution.

The collection of separated solids can be achieved through various mechanisms, which are further described in the following section.

Filtration centrifuges come in a wide range of options.

The user can easily remove the separated solids from a peeler centrifuge by ‘peeling’ off the cloth media. In contrast, a basket centrifuge relies on a perforated ‘basket’ to keep the solids separated.

Screening centrifuges feature slotted bowls with an articulated pusher arm to effectively remove solids. An additional wire mesh screen helps to retain and separate the accumulated solids.

Sedimentation or Solid Bowl

Decanter-Cross-Section-600
Decanter Centrifuge Cross Section Diagram

The sedimentation centrifuge utilises a solid bowl, also referred to as a ‘solid bowl centrifuge’, and does not rely on a flow-through or perforated screen or media.

According to industry experts, the centrifugal force leads to the accumulation of denser solids on the bowl wall, while the lighter liquid separates from these solids. An exit pathway for the separated fluid is then created.

These sedimentation centrifuges include the added benefit of a ‘solid bowl’ feature.

alfa-laval-disc-centrifuge-bowl-cross-section-1000
Disc Centrifuge Cross Section Diagram

This particular centrifugal force is responsible for separating immiscible liquids and solids within a 3-phase centrifuge. The process is achieved by differential settling, separating all three phases effectively.

There are two types of solid bowl centrifuges: decanter centrifuges and disc stack centrifuges.

Difference Between Filtration and Sedimentation Centrifuges

One key distinction between filtration and sedimentation centrifuges is their bowl design. While filtration centrifuges have a pass-through bowl that allows for the separation of liquid and solids, sedimentation centrifuges use a solid bowl and differential settling to achieve this separation.

For further clarification, here are the key distinctions between the two variations of centrifuges.

Gain a more detailed understanding by reading our informative article on the technical distinctions between basket (filtration type) and decanter (sedimentation type) centrifuges.

Separation Efficiency

The efficiency of industrial centrifuges is largely determined by their design and operating parameters, including flow rate, fluid viscosity, centrifugal force, and other factors, resulting in variation in particle size.

The efficiency of a filtration-type centrifuge is determined by the size of the media or mesh perforations, with particles larger than the perforation size being separated by the bowl wall or screen. The application of this type of centrifuge is limited by the preset size of the screen media or mesh.

The sedimentation centrifuge employs centrifugal force to separate solids. The scroll effectively removes all separated solids from the bowl, regardless of their size. As a result, this type of centrifuge can effectively separate a variety of particle sizes from liquids.

The sedimentation centrifuge typically has a higher particle size efficiency compared to filtration-type centrifuges.

Gravitational or Centrifugal Force

Sedimentation centrifuges rely on the difference in specific gravity between solids and liquids to separate them, requiring a high centrifugal force (RCF) for efficient separation.

Filtration centrifuges require a reduced g-force for liquid to pass through the bowl perforations.

When comparing sedimentation-type and filtration-type centrifuges, it is important to note that the former typically have a centrifugal force of 3,000 to 10,000 Gs, while the latter have a force of less than 2,000 Gs. This difference in force can greatly impact the separation process of the centrifuge. Remember to consider this when choosing the right type of centrifuge for your needs.

Separated Solids Extraction

The sedimentation centrifuge expels the separated solids continuously while in the process of sedimentation. An auger, rotating within the bowl, is responsible for pushing out the separated solids.

The separated solids in a filtration-type centrifuge are collected by a scraper that periodically scrapes them out of the bowl.

Separated Liquid Discharge

The filtration centrifuge’s flow-through bowl effectively releases liquid from the bowl. The separated fluid naturally discharges from the centrifuge vessel due to gravity.

The sedimentation centrifuge’s separated fluid is rotated at high speeds, while the built-in pump converts rotational energy into pressure to discharge the liquid.

Replaceable Media

One feature of a filtration centrifuge is its use of replaceable filtration media, which can result in added expenses for labor and materials.

This centrifuge relies on the increased force of gravity to effectively separate liquids from solids, eliminating the need for replaceable media and saving both time and cost.

Centrifuge Design

Sedimentation and filtration centrifuges differ in design. It’s important to understand the key distinctions between these types of centrifuges.

Moving Parts

This section focuses on the internal moving parts of the centrifuge, such as the rotating bowl which is a common component in all centrifuges.

The centrifuge’s filtration type often includes an articulated scraper or blade to periodically remove separated solids from the inside surface of the bowl. These solids are then released from the bowl by the force of gravity.

During the solids ejection process in the sedimentation centrifuge, the rotating scroll continuously pushes out the separated solids under the influence of centrifugal force within the rotating bowl.

Bowl Construction

The filtration-type centrifuge features a bowl with perforations that effectively separate liquids from solids. These perforations are crucial in determining the size of the separated particles.

A sedimentation centrifuge, commonly referred to as a solid bowl centrifuge, features a solid bowl design that increases its durability and extends its lifespan compared to perforated bowl designs.

Erosion Protection

To ensure the longevity of centrifuges, it is crucial to apply erosion-protecting coatings to areas of the bowl that come into contact with abrasive particles during operation. This helps prevent erosion and prolongs the lifespan of the centrifuge.

The filtration centrifuge’s bowl perforations can become worn over time due to the passage of solid particles, potentially expanding the pore sizes. However, applying erosion protection to these pores may not always be a viable solution.

The durable scraper or plow within the filtration centrifuge may experience wear and tear. However, a tough surface coating on the plow’s edge guarantees exceptional wear resistance.

The scroll flights in the sedimentation centrifuge bowl continuously push out the solids, making contact at all times and subject to erosion wear. To prevent this, the use of an erosion-resistant material like tungsten carbide is recommended to protect the scroll flights.

Capacity

An industrial centrifuge’s capacity (throughput) is determined by the volume of fluid it can process in a given time. For example, a decanter-type centrifuge can handle anywhere from 5 to over 300 gallons per minute, while an industrial disc centrifuge has a range of 1 to over 200 gallons per minute. Keep in mind that the actual processing capacity may vary based on the type of fluid and level of contaminants.

Compare Filtration & Sedimentation Centrifuges

The key distinguishing factor between industrial centrifuges is their bowl design – filtration centrifuges feature a pass-through bowl, while sedimentation centrifuges have a solid bowl. Other differentiating factors include separation efficiency, centrifugal force rate, and overall design.
