3 Phase Decanter Centrifuge

GN 3 phase decanter centrifuge is used to separate two liquid phases from one solid phase at the same time. As is known, decant centrifuge principle of separation is by G force. Because of the different densities of the (immiscible) liquids and the solid , so all three phases can be discharged simultaneously using the GN 3 Phase decanter centrifuge. GN Solids Control design and manufacture three phase decanter in different bowl size include: 360mm, 450mm and 550mm.

However, to do the 3 phase separation, the solid phase must be the specifically heaviest phase and the two liquid phases should have different densities.

The structure and principle of the three phase decanter centrifuge are similar to the two phase decanter centrifuge. The difference is the way of the liquid discharged. There are two liquid phases in separation in a 3 phase decanter centrifuge. A higher density liquid phase is discharged under pressure, and the lower density liquid is discharged without pressure. Following is the principle drawing of the 3 phase decanter centrifuge.
