GF model tubular centrifuge is used to separate various emulsion, especially the liquid-liquid separation whose two-phase specific gravity’s difference is very small, and liquid-liquid-solid separation which contains little impurities, such as: transformer oil, turbine oil, lubricating oil, fuel oil, dyes, grease, the saponated substances, various micro-powder materials, the purification of span-80 liquid, various oral, various pharmaceutical liquid, the separation of “920”, the separation of blood plasma biological medicine, the blood plasma extracting from animal blood, the purification of edible oil/ cai plate soaking liquid/ polyphenols/ concentrated soy lecithin, the oil-water separation and the waste water treatment, etc.
GQ model tubular centrifuge is used to separate those suspension which is difficult to separate, especially the solid-liquid separation with small concentration, big viscosity, fine solid particles, and the solid-liquid weight difference is smaller, such as the clarification of various medical liquid/ glucose chlorhexidine/ malic acid/ various oral liquid/ rhizome menispermi, the extraction of coal tar/ graphite slag/ various protein/ alginate/ pectin, the purification of honey, the separation of blood, the sedimentation of vaccines mycelium/ glucose solution, and the purification of paints/ dyes/ various resins/ rubbers solutions.
Working Principle of Centrifuge Separators
How It Works
Centrifuge separators are vital tools across various industries. They are intended for mechanical separation of solid-liquid, liquid-liquid, and gas-liquid mixtures based on density differences. Their operation hinges on the principle of centrifugal force, which is generated by spinning the mixture at high speeds within a rotating bowl. This force drives heavier particles outward to the perimeter, while lighter components move toward the center, allowing for efficient and effective separation.
Key Components and Operation
1.Feed System: The mixture is introduced into the centrifuge separator through an feed pipe. The design of the feed system ensures a smooth entry and even distribution within the rotating bowl.
2.Rotor: The rotor creates strong centrifugal force by high-speed spinning, usually located in the center of the separator.
3.Bowl: Inside the bowl, centrifugal force segregates components into distinct zones. For instance, heavier solids collect at the outer edge, while lighter liquids or less dense components remain closer to the center. Depending on the type of centrifuge, the bowl can be horizontal or vertical.
4.Discharge Mechanism: After separation, different phases are removed from the centrifuge. The heavier solids are typically expelled from the bowl’s outer edge, while lighter phases exit through different outlets, depending on the centrifuge type.
5.Control Panel: This panel allows the operator to manage the centrifugation process, including monitoring performance and adjusting the rotor's speed.

Types of Centrifuge Separators
By application areas:
1.Purifiers: Efficiently separate liquid-liquid mixtures, ideal for precise separation of different liquid phases.
2.Concentrators: Separate liquid-liquid mixtures while adjusting the concentration of the light phase, suitable for applications needing concentration control.
3.Clarifiers: Remove unwanted solids from liquid mixtures to produce a clean, sediment-free product, reducing the need for additional filtration.
By design and operational configurations
Horizontal Centrifuge: Features a horizontally aligned bowl, effective for separating liquids and solids. It is particularly used in applications where continuous discharge of solids is required.
Vertical Centrifuge: Uses a vertically oriented bowl for a more compact design and efficient separation, suitable for applications in food processing and wastewater treatment.
Disc Stack Centrifuge: Incorporates a stack of conical discs to increase surface area for separation. This design allows for finer separation, making it ideal for industries such as dairy and chemical processing.
Decanter Centrifuge: Combines a horizontal bowl with a screw conveyor for continuous solid-liquid separation. It is commonly used in wastewater treatment and oil production.
Tubular Centrifuge: Features a vertical, tubular bowl for precise separation of fine solids from liquids. It is often used in laboratory settings and small-scale applications.
Advantages of Centrifugal Separators
Centrifuge separators have been effectively used for separating liquids and solids across diverse industries. Their design eliminates the need for filters, bags, screens, or cartridges, simplifying maintenance compared to traditional filtration systems. Key advantages include:
1:High Separation Efficiency
They achieve 98% efficiency for particles of 40 microns in a single pass, with practical effectiveness for particles of 44 microns, solids with a gravity of 2.6, and water with a gravity of 1.0. This high level of efficiency is particularly valuable for applications requiring precise separation.
2: Minimal Liquid Loss
Traditional filtration methods, such as sand media filters and automatic strainers, rely on consumable filters that often lead to liquid loss during cleaning or replacement. In contrast, centrifugal separators use centrifugal force to separate components, eliminating the need for filters and thus minimizing liquid loss.
3: Fast Separation Speed
Centrifuge separators can process large volumes of fluid rapidly, with some models capable of handling up to 3,000 gallons per minute. This speed is crucial in industries such as food and beverage manufacturing, pharmaceutical production, and wastewater treatment, where efficient processing is essential for meeting production targets and regulatory standards.
4: Reduced Downtime
Centrifuge separators use a spinning vortex to separate particles, eliminating the need for conventional filters. This avoids filter clogging, reducing maintenance needs and downtime.
5: Durable Construction
Made from robust materials such as 304L/316L stainless steel or mild steel, centrifuge separators can withstand harsh environments. Their durability ensures long-lasting performance, often exceeding 15-25 years of service life.
6: Cost-Effectiveness
Due to their low maintenance requirements and high efficiency, centrifuge separators can lead to significant cost savings over time. They reduce operational costs associated with filter replacements and downtime, making them a smart investment for businesses.
7: Adaptability
Centrifuge separators can handle a wide range of mixtures, including solid-liquid, liquid-liquid, and gas-liquid separations. This versatility allows them to be used in various applications, from wastewater treatment to oil recovery.
