 What Is a Decanter Centrifuge?

A decanter centrifuge (also called horizontal spiral decanter) is a high-performance industrial machine designed for continuous solid-liquid separation and 3-phase oil-water-solid separation. Produced by REYES Machinery (China) — a professional high-tech manufacturer integrating R&D, production, sales and after-sales service for centrifuges — it uses high-speed rotation to generate strong centrifugal force, separating materials into different phases based on their density differences—making it a core equipment for sludge dewatering, oily sludge treatment, wastewater purification, and waste oil recovery across multiple industries.

Unlike disc stack centrifuges, the decanter centrifuge features a horizontal rotating drum with a screw conveyor, enabling 24-hour continuous feeding and discharging without shutdown. This makes it ideal for large-volume material processing, especially for high-solid-content slurries that require efficient dewatering and clarification.

Key Features of REYES Machinery (China) Decanter Centrifuge

• High Efficiency Separation: Equipped with high centrifugal force (1500–4000 G), our decanter centrifuge ensures thorough solid-liquid separation and 3-phase separation, removing fine particles and impurities effectively.
• Continuous Working Performance: No need for manual shutdown for slag discharge—realizes 24/7 automatic operation, saving labor costs and improving production efficiency for industrial applications.
• Low Sludge Moisture Content: The decanter centrifuge reduces sludge moisture to 40%–60%, significantly reducing sludge volume and transportation costs for sludge dewatering projects.
• Corrosion & Wear Resistant: Drum and screw are made of 316L stainless steel or duplex steel 2205, suitable for corrosive materials in chemical, oilfield, and wastewater treatment industries.
• Adjustable Differential Speed: Frequency conversion control for differential speed, adapting to different material concentrations and separation requirements (ideal for oil-water separation and sludge dewatering).
• Energy Saving & Environmental Friendly: Low power consumption, full sealed structure to prevent odor leakage and pollution, complying with global environmental standards.

FAQ About Decanter Centrifuge 

Below are the most frequently asked questions about decanter centrifuge, covering key concerns about solid-liquid separation, sludge dewatering, operation and maintenance.

Q1: What is a decanter centrifuge used for?

A decanter centrifuge is a professional industrial equipment mainly used for solid-liquid separation, 3-phase oil-water-solid separation, and sludge dewatering. It is widely applied in wastewater treatment, oilfield, chemical, food, and mining industries to clarify liquids, dewater sludge, and recover valuable materials like waste oil.

Q2: What is the difference between 2-phase and 3-phase decanter centrifuge?

A 2-phase decanter centrifuge is designed for simplesolid-liquid separation, separating solid particles from liquid efficiently.

A3-phase decanter centrifuge can separate three components simultaneously—oil, water, and solid, which is perfect for oily sludge treatment, oilfield drilling mud separation, and waste oil recovery.

Q3: How efficient is the decanter centrifuge in sludge dewatering?

Our decanter centrifuge achieves high-efficiency sludge dewatering, reducing sludge moisture content to 40%–60%. This significantly reduces sludge volume, lowers transportation and disposal costs, and improves work efficiency for industrial sludge treatment projects.

Q4: What factors affect the separation effect of a decanter centrifuge?

The main factors affecting the separation effect include centrifugal factor (rotating speed), feed solid concentration, feed flow rate, material viscosity and temperature, and the design of the drum and screw. Proper adjustment of these factors ensures optimal solid-liquid separation and oil-water separation performance.

Q5: Is the decanter centrifuge easy to maintain and operate?

Yes, our decanter centrifuge features automatic 24-hour continuous working, no need for manual shutdown for slag discharge. It is equipped with frequency conversion control for easy operation, and all components are made of corrosion-resistant materials, reducing maintenance frequency and cost. We also provide professional guidance for operation and maintenance.

Q6: Can the decanter centrifuge be customized for specific needs?

Absolutely. We provide customized decanter centrifuge solutions according to your specific requirements, including capacity, separation type (2-phase or 3-phase), material compatibility, and solid-liquid separation precision, to meet the unique needs of different industries and projects.
