Disc Stack Centrifuge

GN Disc Stack Centrifuge is also called Disc Centrifuge or Disc Separator or Conical Plate Centrifuge, which can be used to separate solid and liquid under high-speed centrifugal force. GN Disc Stack Centrifuge is Vertical centrifuge, it is driven by one motor that rotates at high speed. Inside the rotating bowl of the disc Centrifuge is a set of disc-shaped parts nested with each other-commonly known as discs. A small gap among the discs, which are used for centrifugal sedimentation of materials.

    2 Phase Disc Stack Centrifuge

    3 Phase Disc Stack Centrifuge

    GN Disc Stack Centrifuge is also called Disc Centrifuge or Disc Separator or Conical Plate Centrifuge, which can be used to separate solid and liquid under high-speed centrifugal force. GN Disc Stack Centrifuge is Vertical centrifuge, it is driven by one motor that rotates at high speed. Inside the rotating bowl of the disc Centrifuge is a set of disc-shaped parts nested with each other-commonly known as discs. A small gap among the discs, which are used for centrifugal sedimentation of materials.

    Suspension liquid (or emulsion) is feed by gravity usually or a feeding pump into the bowl of the disc Centrifuge. When the suspension liquid (or emulsion) flows through the gap between the discs, solids (or droplets) are settled on the disc and become sediment (or liquid layer), the sludge slides along the surface plate of the disc to separate from the disc and accumulates in the inner bowl where the diameter is large, and the separated liquid is discharged from the bowl through the liquid outlet.

    For the 3-phase disc Centrifuge, there are two centripetal pumps inside, which can discharge the two immiscible liquid phases having difference densities. The function of the discs in the disc Centrifuge is to shorten the settling distance of solid particles (or droplets) and enlarge the effective settling area of the bowl in order to greatly improve the production efficiency. The solids accumulated in the bowl can be discharged through the automatic slag discharge mechanism without disc centrifuge stopping. Solid-liquid-liquid 3-phase separation or solid-liquid separation can be achieved by using GN Disc Stack Centrifuge.

    All contacting parts of the GN Disc Stack Centrifuge is made of high-grade stainless steel, which effectively reduces the chemical interaction between the separated material and the surface of the contacting part. The separated light and heavy phase liquid materials are output by two centripetal pumps of different sizes. This machine adopts upper feeding, which has lower inlet pressure on the material. Hydrodynamic coupling and a pair of helical gears or belt drive are used in the power transmission. The speed increase is stable and overload protection can be performed.

    The slag discharge action of the sliding piston is automatically controlled by a PLC fully automatic control cabinet specially designed with safety protection devices. It is high level automation, strong adaptability for process adjustment, and convenient adjustment, low noise and good separation effect.
