Product Description

A decanter centrifuge is a highly efficient type of centrifuge meticulously designed for the purpose of separation. This sophisticated process operates continuously, harnessing the immense power of centrifugal force to achieve separation. The mixture is seamlessly fed into the centrifuge, where the impressive spinning action generates centrifugal forces that skillfully separate solids from liquids.

When tasked with separating solid/liquid mixtures boasting a high solids content, decanter centrifuges emerge as the optimal solution. These solid-shell scroll centrifuges or decanters, stand apart from chamber filter presses by their ability to run continuously. They excel at separating finely distributed solid particles from suspensions through robust centrifugal forces.

Decanters find indispensable utility across numerous industries worldwide. These centrifuges are meticulously calibrated for each specific application, with uses spanning from sludge dewatering, classification, wet classification, to precise sorting of solids.

To achieve peak efficiency, solid bowl decanter centrifuges require custom design tailored to accommodate specific separation processes.

• A decanter centrifuge is a sophisticated device engineered to separate solids from liquids in a mixture, functioning as a continuous process.
• By feeding the mixture into the centrifuge, centrifugal forces generated by its spinning mechanism expertly separate solids from liquids.
• The resultant separated solids and liquids are then efficiently discharged through separate outlets, ensuring streamlined operation.
• Decanter centrifuges are integral across diverse industries, including chemical, pharmaceutical, food processing, and environmental engineering sectors.
• These centrifuges are especially valuable for separating solids that are exceedingly fine or dense, challenging for other methods such as sedimentation or filtration.
• They also excel in dewatering sludge and separating emulsions, showcasing their versatility.
• Renowned for their high efficiency, low maintenance demands, and capability to process large volumes, decanter centrifuges are an industry staple.

• Decanter centrifuges operate on the principle of separation via buoyancy, enhanced by continuous spinning, resulting in g-forces between 1000 to 4000 G's. This reduces settling time from hours to mere seconds, delivering rapid and efficient separation.

  A decanter acts as a sedimentation tank revolving around an axis. Solid particles, denser than liquid, migrate to the bottom, forming sediment. In a centrifuge, centrifugal acceleration expedites this process, allowing for swift and efficient separation.
