Separation Decanter Centrifuge

The decanter centrifuge is mainly operated by sedimentation, which separates the solid-phase suspended matter with a higher density than the liquid in which the suspended matter is located. Similarly, two liquid phases with different densities can be effectively separated by applying centrifugal force through a separation centrifuge. The application of decanter centrifuges in the separation industry has many advantages, for example: it can process liquids with high slurry concentration and produce a dry solid phase, can work unattended for a long time, and reduce the use of filter aids.

Applications For Separation Decanter

The decanter centrifuge can be used for most types of liquid-solid and liquid-liquid separation, and its ability to handle various feed slurry concentrations increases its versatility. And it can separate suspensions composed of two or more phases of different densities. Applications range from food, beverage and pharmaceuticals to marine and energy, to water and waste treatment, mineral oil and mineral oil product processing, and pigment recovery in paints.

The decanter centrifuge consists of a high-speed rotating cylindrical bowl. The inside of the bowl is a screw, and the differential speed between the bowl and the screw provides the transmission power to collect and remove the solid phase accumulated on the inner wall of the bowl. The decanter centrifuge can remove large particles with high solid content from the slurry or liquid, and separate two liquid phases with different densities by centrifugal force. The clarified and separated light liquid phase is discharged on the liquid side of the decanter by gravity, while the heavy liquid phase leaves the decanter together with the solids.

Why Choose ZK Decanter Centrifuge ?

  • ease to use decanter
    Easy Operation

    ZK decanter can run continuously and automatically. The control of the decanter centrifuge is completed through the touch screen of the control panel, and the one-key start and stop of the decanter can be realized through the control panel. The control panel interface is simple and easy to be understood, and operators can easily monitor the working status and understand the operating parameters.

  • durable

    All wear-prone areas of ZK centrifuges (separation liquid outlet, solids discharge output, screw conveyor and solids discharge section) are made of abrasion resistant material, and the rotating parts are made of high-strength centrifugally cast stainless steel. For the wear-resistant requirements of special industries, replaceable hard alloy wear-resistant pieces are added to the spiral blades.

  • lubrication
    Lubrication Ways

    In order to meet the actual needs of different customers, ZK decanter centrifuge provide three different lubrication ways (grease pump grease lubrication, lubricating oil circulating lubrication and oil mist lubrication) for customers to choose. All lubrication systems can re-lubricate the rotor bearings during centrifuge operation.

  • security
    Safety and Security

    ZK decanter differential speed automatic control technology can automatically adjust the screw conveyor differential speed, to prevent overload and blockage. At the same time, ZK decanter centrifuge has vibration protection, bearing temperature protection and overload protection system. This can avoid critical operating conditions and prevent damage to centrifuge components and bearings.
