A Decanter centrifuge is a continuous solid–liquid separation machine that uses centrifugal force to remove solids from liquids. It is widely used in wastewater treatment, oil and gas, mining, chemical processing, and food industries due to its high efficiency, compact design, and low maintenance requirements.
Key Characteristics of a Decanter Centrifuge
Continuous operation without interruption
High-efficiency solid–liquid separation
Strong dewatering performance
Compact structure and small footprint
Automated control with minimal manual operation
Simple maintenance and long service life
How Does a Decanter Centrifuge Work?
A Decanter centrifuge works by rotating a bowl at high speed to generate strong centrifugal force. Solids with higher density settle against the bowl wall, while clarified liquid forms an inner layer. A screw conveyor (scroll) rotates at a slightly different speed to continuously convey the separated solids toward the discharge ports, enabling uninterrupted separation.
What Are the Advantages of a Decanter centrifuge?
The main advantages of a decanter centrifuge include:
High separation efficiency: Capable of handling fine particles and high solids content
Fully continuous process: Feeding, separation, and discharge occur simultaneously
Low labor demand: Automated operation reduces manual intervention
Reliable performance: Stable operation under varying feed conditions
Cost-effective maintenance: Simple daily inspection and reduced downtime
Is a Decanter Centrifuge Easy to Maintain?
Yes. A Decanter centrifuge requires only routine maintenance, such as regular inspection, lubrication, and wear-part monitoring. Compared with other separation equipment, maintenance is straightforward and does not require frequent shutdowns, helping reduce operating costs.
Why Choose GN Separation Decanter Centrifuges?
GN Separation’s Decanter centrifuges are manufactured using high-end CNC lathes, CNC machining centers, and CNC gantry milling machines to ensure precision. In addition to standard dynamic balancing, GN applies high-speed dynamic balancing at actual operating speeds, which minimizes vibration, reduces mechanical stress, and improves long-term reliability.
GN decanter centrifuges are widely used in sludge dewatering, oilfield wastewater treatment, mineral processing, and industrial wastewater treatment. GN products have been exported to more than 60 countries and regions worldwide.
