INDUSTRIAL CENTRIFUGES
Precision separation, reliable performance.
Trusted in food, chemical, pharmaceutical and wastewater industries.
You are here: Home » Special Topics » Industrial Centrifuge
Industrial centrifuges are essential equipment used to facilitate material separation, purification, and dehydration by utilizing centrifugal force. Through high-speed rotation, they generate a strong centrifugal field that rapidly separates components in a mixture based on differences in density and particle size.

In practical applications, they perform four key processes:

1. Solid-Liquid Separation
Used for clarifying liquids or concentrating solids. Common applications include sludge dewatering in wastewater treatment, milk skimming in dairies, and bacterial harvesting in biopharmaceuticals.

2. Liquid-Liquid Separation
Separating immiscible liquids with different densities. This is widely used for oil-water separation in the petrochemical industry and solvent recovery.

3. Classification & Purification
Achieving precise enrichment of target components and removal of impurities. Ideal for pharmaceutical production and herbal/plant extraction.

4. Dewatering & Drying
Reducing the moisture content of solid materials to lower processing costs. Typical uses include dewatering mine tailings and drying food residues.
Widely applied in the chemical, food & beverage, biopharmaceutical, and environmental protection industries, industrial centrifuges (including Disc Stack and Decanter models) are critical for improving production efficiency and product purity.

    Replacement intervals depend on operating hours, material abrasiveness, and maintenance. Bearings and seals are common wear items; we recommend following the maintenance schedule provided.

  • Q What is the typical noise level of an industrial centrifuge?

    A
    Noise depends on size, speed, and enclosure. Many industrial centrifuges range from 75–85 dB(A). Sound insulation enclosures can reduce noise further if required.

  • Q What is “residence time” and how is it adjusted?

    A
    Residence time is how long material stays in the bowl. It can be adjusted by changing bowl speed, feed rate, or (in decanters) scroll speed/differential speed to optimize clarity or cake dryness.

  • Q How does temperature affect centrifuge performance?

    A
    Higher temperatures can reduce viscosity (improving separation) but may require special seals, gaskets, and material selection. We can specify the machine for your process temperature range.

  • Q What types of drives are available (belt, direct, variable frequency)?

    A
    Options include belt drive, direct drive, and variable frequency drive (VFD). VFD is often preferred for better speed control, energy savings, and smoother start-up.

  • Q What is the difference between a 2-phase and 3-phase centrifuge?

    A
    A 2-phase centrifuge separates one liquid and one solid phase. A 3-phase unit can separate two immiscible liquids plus solids (e.g., oil + water + solids), common in petrochemical and edible oil applications.milk

  • Q How do I calculate the required capacity for my process?

    A
    Capacity depends on feed flow rate, solid content, residence time, and desired clarity/dryness. We usually ask for your L/h or m³/h, % solids, and target (e.g., “clarified liquid” or “dry cake”) to size the machine.

  • Q What materials are commonly used for the bowl and discs?

    A
    Common materials are 304 stainless steel (general purpose) and 316L stainless steel (better corrosion resistance for food, pharmaceutical, and chemical applications). For highly corrosive media, special alloys can be used.

  • Q What is a separation factor (G-force), and why is it important?

    A
    The separation factor is the ratio of centrifugal force to gravitational force. A higher G-force generally means faster and more efficient separation, especially for fine particles or low-density differences.
