The disc centrifuge operates on the principle of high-speed rotation to separate particles in a liquid based on their density. As the centrifuge spins, the centrifugal force causes denser particles to move outward and collect at the periphery of rotating discs, while lighter components remain closer to the center or form distinct layers based on their densities. By adjusting the rotation speed and time, efficient separation of particles such as solids, liquids, and gases can be achieved. Disc centrifuges are commonly used in industries like biotechnology, pharmaceuticals, and food processing for tasks such as separating cells, clarifying liquids, and purifying products.
The disc centrifuge main application is liquid-solid separation with solid content below 10% and solid phase particle diameter greater than 0.5 microns.
1.Commonly used oil-water separation are: vegetable oil, animal oil, fuel oil,
2.Food: Juice clarification, yeast extraction, etc.
3.Pharmaceutical industry: vaccines, bacteria, glucose etc.
4.Chinese Medicine: Separation and clarification of plant extracts.
1)DHY is used for liquid-liquid or liquid-liquid-solid separation. Mainly to separate two incompatible liquids, for example: oil-water separation. Skim milk
2) DHC is used for liquid-solid separation, mainly to separate the solid phase in the liquid, such as the pomace in fruit juice. Chinese medicine extraction, etc.
Main features:
1) fully automatic: the whole process of feeding, separating, cleaning and discharging is fully automatic and can be controlled by PLC.
2) high separation factor, usually between 5000 and 9300.
3) large output: the maximum processing capacity can reach 1-10 tons/hour, which is suitable for mass production.
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.
