A three-phase decanter centrifuge is a specialized type of decanter centrifuge designed to separate a mixture into two liquid phases and one solid phase simultaneously. Its operating principle is based on the difference in specific gravity between the solid and liquid phases. When the mixture enters the rotating bowl, the powerful centrifugal force—thousands of times stronger than gravity—forces the solids to settle against the bowl wall, while the two liquid phases stratify into distinct layers. A specially designed mechanism then continuously discharges the separated solids and liquids, completing a fully enclosed and automatic separation process. Continue reading

How to Increase the Efficiency of a Decanter Centrifuge
The decanter centrifuge is highly effective for the liquid-solid separation, especially when the solid particles are small, the density difference between phases is minimal, and the separation is challenging. It is also suitable for separating liquid-liquid two-phase systems or liquid-solid-liquid three-phase systems. As a result, decanter centrifuges have been widely adopted across various industries. Below is an overview of the current practical applications.
How to increase the working power of a decanter centrifuge
Decanter centrifuges are particularly effective for liquid-solid separation processes involving fine particles, minimal density differences between phases, and otherwise challenging separation tasks. They are also widely applied in two-phase (liquid-liquid) and three-phase (liquid-liquid-solid) separation scenarios. As a result, they have become an essential part of many modern industrial processes. Continue reading
Operation Management of Decanter Centrifuge
When the decanter centrifuge operates, the high-speed rotation of its drum generates a strong centrifugal force. This force drives solid particles—denser than the liquid phase—toward the inner wall of the drum, forming a solid layer (also known as the solid ring layer due to its annular shape). The liquid, having lower density and subject to less centrifugal force, remains inside the solid layer, forming the liquid ring layer. Continue reading
