Decanter Centrifuges: An Overview
Decanter centrifuges are among the most widely-used devices in the industrial and manufacturing sectors. They are rotating mechanical devices that separate solid and liquid components from a mixture through centrifugal force. Decanter centrifuges are used in various applications, including wastewater treatment, food processing, oil and gas drilling, pulp and paper production, and chemical and pharmaceutical manufacturing, among others. Two of the most common types of decanter centrifuges are horizontal and vertical decanter centrifuges.

The Basic Differences between Horizontal and Vertical Decanter Centrifuges
The primary difference between horizontal and vertical decanter centrifuges is the orientation of their rotating drums. In a horizontal decanter centrifuge, the drum rotates in a horizontal plane, while in a vertical decanter centrifuge, the drum rotates in a vertical plane. This difference in orientation affects the way the centrifuge separates the solid and liquid components of a mixture.
Horizontal decanter centrifuges are used in applications involving high capacity and continuous separation of solid and liquid phases from a mixture. They are particularly useful in applications where the sedimentation rate of solid particles is high, such as in wastewater treatment and mining operations.
Vertical decanter centrifuges, on the other hand, are better suited for applications that involve high separation efficiency and low liquid retention. Because of their vertical orientation, the solid particles settle more quickly to the bottom of the drum, allowing for faster and more efficient separation of solid and liquid components. Vertical decanter centrifuges are commonly used in food processing, chemical and pharmaceutical manufacturing, and oil and gas drilling operations.
Operational Differences between Horizontal and Vertical Decanter Centrifuges
The operational differences between horizontal and vertical decanter centrifuges are significant. In a horizontal decanter centrifuge, the mixture is fed into the drum through a distributor, which disperses the mixture into the rotating drum’s cylindrical section. The rotating drum creates centrifugal force, which separates the solid and liquid phases of the mixture. The solids collect on the inner surface of the rotating drum and are transported by a scroll conveyor to the discharge end of the decanter centrifuge. The clarified liquid exits the centrifuge via weir plates at the opposite end.
In a vertical decanter centrifuge, the feed is introduced into the rotating drum through a stationary inlet pipe, which is located at the top of the drum. As the mixture enters the drum, it passes through a distributor that disperses the mixture evenly over the entire surface area of the drum. The drum rotation creates centrifugal force that causes the solid particles to move outward towards the bowl’s walls, while the liquid phase moves towards the center of the bowl. The solids are then transported to the discharge end of the centrifuge by a conveyor, while the clarified liquid exits the centrifuge via a separate outflow pipe.
Selection of Decanter Centrifuges
The choice between a horizontal and vertical decanter centrifuge depends on several factors, including the type of application, the required separation efficiency, and the physical and chemical properties of the solid and liquid components in the mixture. Horizontal decanter centrifuges are generally more suitable when high capacity and continuous separation of solid and liquid phases is required. Vertical decanter centrifuges are better suited for applications that require high separation efficiency and low liquid retention. Both types of decanter centrifuges are available in a range of sizes and configurations to meet the specific needs of a particular application.

Conclusion
Decanter centrifuges are an essential part of many industrial and manufacturing processes, and the choice between a horizontal and vertical decanter centrifuge will depend on the specific application’s needs. A horizontal decanter centrifuge is optimal for high capacity and continuous separation of solid and liquid phases, while a vertical decanter centrifuge is preferred for high separation efficiency and low liquid retention. Understanding the differences between the two types of decanter centrifuges will help ensure that the right equipment is selected for a specific application, resulting in improved process efficiency and productivity.
