Product Description

A decanter centrifuge stands as an exceptional device engineered for the efficient separation of solids from liquids within a mixture. This remarkable process operates continuously, harnessing the power of spinning force to meticulously divide the mixture. As the centrifuge spins, the solids are expertly extracted from the liquids, driven by the robust centrifugal force generated.

For mixtures with a high solids concentration, decanter centrifuges are the premier choice. Utilizing a solid-shell scroll, these centrifuges —also referred to as decanters—operate without interruption, unlike chamber filter presses. The mighty centrifugal forces diligently separate finely distributed solid particles from the suspension.

Decanters have found indispensable applications across numerous global industries. They are meticulously tailored to meet specific needs, ranging from sludge dewatering to various forms of classification, and even the sorting of solids.

To achieve the pinnacle of performance, solid bowl decanter centrifuges are custom-crafted to align with distinct separation processes.

• A decanter centrifuge serves as a sophisticated solution for separating solids from liquids within a mixture, leveraging a continuous process driven by centrifugal force.
• The mixture is introduced into the centrifuge, where the powerful centrifugal force efficiently separates solids from liquids during the spinning process.
• After separation, the distinct solid and liquid components are discharged seamlessly through individual outlets.
• Decanter centrifuges are multi-faceted tools employed across diverse industries such as chemical, pharmaceutical, food processing, and environmental engineering.
• Renowned for their ability to separate particularly fine or dense solids, they excel where traditional methods like sedimentation or filtration fall short.
• Additionally, these centrifuges adeptly handle sludge dewatering and the separation of emulsions with remarkable efficiency.
• Celebrated for their impressive efficiency, minimal maintenance needs, and capacity to manage substantial material volumes, they are a trusted industry staple.

• Decanter centrifuges capitalize on the principle of buoyancy-based separation. They amplify settling velocity, achieving a g-force between 1000 and 4000 G's. This drastically reduces the settling time from hours to mere seconds, offering expedited and controllable results.

  Envision a decanter as a sedimentation tank, oriented around an axis. Denser solid particles naturally gravitate to the tank's bottom, forming a sediment layer. In a centrifuge, centrifugal acceleration amplifies separation efficiency, with forces around 3000 g accelerating the process far beyond simple gravity.

  Harness the power of the 3-phase decanter centrifuge, a marvel of engineering that seamlessly separates three distinct phases in a single streamlined operation. Imagine effortlessly dividing oil and water—two substances that naturally resist fusion due to their different densities—while simultaneously extracting a solid phase. The ingenious design allows water to nestle between the oil and solids layers, enabling the effortless extraction of these liquids post-separation. Just like in 2-phase separations, the robust scroll efficiently guides the solids to the designated discharge points.

  Three-phase separation technology is revolutionizing a range of industries with its versatility and efficiency. Key applications include the production of exquisite edible oils, such as the much-loved olive oil, the eco-friendly processing of oil sludge, and the innovative creation of biodiesel. These are just a few examples of how this technology is leading the way in modern manufacturing and processing.

A decanter centrifuge consists of several vital components, each playing a crucial role in the efficient separation of solids from liquids. These include:

1. Central to the centrifuge's operation, the bowl is a cylindrical chamber rotating around a horizontal axis. Through a carefully engineered feed pipe, the mixture enters the bowl, where centrifugal forces take charge, directing separated solids and liquids to their respective outlets, ensuring pure, high-quality separation.
2. Within the bowl lies the scroll, an intricately designed helical screw that operates at a slightly slower pace. Powered by a robust motor, the scroll expertly moves solids to the bowl's periphery, where they succumb to centrifugal force, seamlessly separating from the liquid phase.
3. Strategically positioned on the bowl's outer wall, this outlet is dedicated to the efficient expulsion of separated solids, ensuring continuous and uninterrupted operation.
4. Located at the bowl's base, this outlet facilitates the smooth discharge of the purified liquids, maintaining a consistent flow and impeccable separation quality.
5. Comprising a high-performance motor and essential components, this system is the powerhouse behind the seamless operation of both the bowl and the scroll.
6. Equipped with advanced sensors and monitoring tools, this system ensures precise control and oversight of the centrifuge's operations, guaranteeing optimal performance.
7. Featuring a robust frame and structural components, this part serves as the backbone, providing steadfast support for the bowl and associated mechanisms.
8. An integral conduit, this pipe meticulously channels the mixture into the centrifuge's bowl, initiating the separation process.
9. This precision pump ensures the consistent and controlled delivery of the mixture into the feed pipe, sustaining a seamless separation process.
10. With its suite of sensors and controls, this system precisely manages the flow of the mixture into the centrifuge, optimizing efficiency and output quality.

1. The journey begins as the slurry enters the centrifuge through an intake pipe, advancing onto a sophisticated conveyor system.
2. Skillfully guided by an internal feed compartment, the conveyor propels the slurry through a nozzle into the heart of the centrifuge—the bowl.
3. Within the bowl, high-speed rotation generates formidable centrifugal forces, setting the stage for rapid separation.
4. In mere seconds, the high-speed rotation distinguishes solid materials from their liquid counterparts, achieving remarkable separation.
5. The conveyor then elevates the solid materials, discharging them efficiently through a precision-engineered nozzle.
6. Once the solids are expelled, the centrifuge releases the purified liquid through a separate outlet, showcasing its remarkable ability to refine liquids with precision. This makes decanter centrifuges a prized asset in waste water treatment facilities, as well as a variety of other industries. Their user-friendly design does not necessitate extensive foundation work, easing installation. With efficiency at its core, these centrifuges save invaluable time and resources, establishing themselves as indispensable in numerous blue-collar industries.

The separation medium is introduced into the center of the infeed chamber of the scroll, where it is accelerated via the feed. Residence time is influenced by the throughput, affecting the separation efficiency.

Within the decanter bowl, the separating medium reaches maximum speed, compelling solids to settle on the inner surface of the bowl, which is characterized by its cylindrical or conical shape for optimal separation.

A gear mechanism within industrial decanter centrifuges creates a speed differential between the bowl and the scroll. This differential speed dictates the quantity of solids expelled in the outfeed, optimizing separation effectiveness.

Pond Depth / Weir Discs

In a decanter centrifuge, the clarified liquid migrates to the cylindrical end of the bowl, exiting through perforations in the bowl cover. Precisely adjustable weir discs/plates allow for the adjustment of the bowl's pond depth, thus determining the filling volume.

The term 'decanter' traditionally invokes images of a graceful vessel with a wide base and narrow neck, often associated with the art of serving fine wines. However, in the world of decanter centrifuges, this term takes on a new dimension. The 'decanter' here alludes to the distinct, elegant shape of the centrifuge bowl, which mirrors that of a classic wine decanter, defined by its cylindrical form with a broad base that tapers into a slim neck, all set to spin dynamically along a horizontal axis.
The intriguing use of 'decanter' in the realm of centrifuges is not merely decorative; it nods to the centrifuge's adeptness at stratifying liquids of varying densities, much like the gentle separation of wine from its sediment. Picture this: the centrifuge bowl, reminiscent of a wine decanter, skillfully isolates the clearer liquid—akin to wine—from the denser sediment or lees. This elegant separation technique ensures purity and quality, akin to pouring a perfect glass of wine.
