At GN Separation, we are committed to delivering solutions for liquid, solid, and liquid-liquid separation. One of our most innovative offerings is the GN 3-Phase Disc Stack Separator, designed to meet the high-speed, stable, and efficient needs of various industries. This system excels in automating the discharge of slag while offering superior separation capabilities, making it the go-to solution for liquid-liquid-solid 3-phase separation or simple liquid-liquid separation.

The Advantages of the GN 3-Phase Disc Stack Separator

The GN 3-Phase Disc Stack Separator operates at an impressively high speed and generates up to 12,000G of centrifugal force, which outperforms standard decanter centrifuges that typically operate at around 3,000G. This significant boost in G-force allows the disc stack separator to more effectively separate liquids with varying specific gravities, producing a clarified liquid output.

However, while the GN 3-Phase Disc Stack Separator is best suited for materials with fine particle content and low solids, its performance can be maximized when paired with a decanter centrifuge for pre-separation. This pre-separation process helps to reduce the solids content and remove larger particles, ensuring that the disc stack separator can achieve optimal performance.

Key Features of the GN 3-Phase Disc Stack Separator

1. High-Speed and Efficient Separation: The GN separator can handle a broad range of separation tasks at high speeds, with models offering up to 12,488G in force.
2. Sealed and Stable Operation: All parts in contact with the material are made from high-grade stainless steel, reducing chemical interactions and wear over time.
3. Automatic Slag Discharge: This unit features a PLC-controlled, fully automatic slag discharge system, enabling continuous, reliable operation.
4. Low Noise and High Efficiency: With optimized design for quiet, seamless operation, the separator meets the demands of various industries, from pharmaceuticals to oil refining.
5. Centripetal Pump System: This feature ensures a stable output pressure, large adjustment range, and ease of operation, enhancing the user experience.

Applications Across Industries

The versatility of the GN 3-Phase Disc Stack Separator makes it a valuable asset across a variety of industries, including:

• Oil Industry: Efficient separation of vegetable and animal oils, including palm oil, rapeseed oil, and fish oil.
• Beverage Industry: Purification of dairy products, fruit juices, and beer.
• Pharmaceuticals: Concentration of extracts like penicillin, vitamins, and antibiotics, as well as fermentation broth clarification.
• Chemical Industry: Separation of lubricant additives, ink, dye, herbicides, and latex synthesis.
• Environmental Protection: Effective for waste treatment, including the separation of food waste and water treatment.

Working Principle

The material to be separated enters the separator’s bowl, where high-speed centrifugal force is applied. The liquid and solids pass through the disc bundle, with heavier materials moving toward the outer edges and lighter liquids moving inward. The system efficiently separates liquids with different specific gravities, discharging them via two centripetal pumps, while solids are discharged automatically at regular intervals.
