Advanced GN 3 Phase Decanter Centrifuge

Our GN 3 phase decanter centrifuge is a state-of-the-art machine specifically designed for solid-liquid-liquid three-phase separation of materials. With over 10 years of experience in the separation industry, we have engineered the most advanced equipment for efficient three-phase separation. This centrifuge is designed for continuous and smooth 24-hour operation, ensuring reliability and efficiency.

Key Components and Design Features

The GN 3 phase decanter centrifuge consists of several key components:

  • Driving System
  • Decanter Bowl: Made from Duplex Stainless Steel SS2205
  • Screw Conveyor Inside the Bowl: Also constructed from Duplex Stainless Steel SS2205, with Tungsten Carbide Tiles for wear protection
  • Cover Box
  • Skid
  • VFD Control Panel

Operational Efficiency

The operational efficiency of our decanter centrifuge is based on the principle of sedimentation. Solid particles, being the heaviest phase, settle quickly, followed by the heavy phase liquid (such as water) and the light phase liquid (such as oil). The different specific gravities create varying centrifugal forces, forming concentric solid and liquid layers. Solids are pushed out by the screw conveyor, while liquids are removed through their respective nozzles.

Applications and Advantages

Our GN 3 phase decanter centrifuge is widely used in industries that require the separation of oil, water, and solids. The main distinction between our 2 phase and 3 phase decanters is that the latter can separate two liquid phases in addition to solids, making it highly versatile and efficient for complex separation tasks.
