GNSX-450 is a three phase decanter centrifuge. The bowl size of GNSX-450 three phase decanter centrifuge is 450mm (18 inch) diameter by 1800mm in length. It is designed for 24 hours continuous and smooth operation throughout the day. It is mainly composed of driving system, decanter bowl, and screw conveyor inside the bowl, cover box, skid and VFD control panel.

Working principle of GN Solids Control 3 phase decanter centrifuge

GN Solids Control 3 phase decanter centrifuge is mainly designed and made for liquid, liquid and solids separation. GN Solids Control 3 phase decanter centrifuge can also be applied to two immiscible liquids with different specific gravities. When the solids and liquid mixture (raw material before separation) rotates into the high-speed rotating bowl internal the 3 phase decanter centrifuge, the solids and liquid mixture rotates synchronously with the drum. As the reason of the different specific gravity, the centrifugal force of the solids and different liquid is different.

The solid particles which with the larger specific gravity are subjected to the greatest centrifugal force, followed by the heavy phase liquid (such as water) and the light phase liquid (such as oil). So the centrifugal force is becoming less from outside to inside according to the magnitude of centrifugal force. A concentric solid layer and two liquid layers are formed.

The Solids phase inside the mixture will be pushed out by the conveyor impeller of the centrifuge bowl, and liquids are removed from their respective nozzles depending on different gravities. As the reason, GN Solids Control three-phase decanter centrifuge can not only separate the solid from the solids and liquid mixture, but also separate the two-phase liquid with different specific gravity in the liquid and liquid mixture. In this case, Solid / liquid / liquid separation can be achieved.

Besides 3-phase decanter centrifuge for oil field and non-oil field, GN Solids Control has other separation equipment to cater for different application, like shale shaker, mud cleaner, desander, desilter, degasser, transfer pumps, drilling waste management equipment, etc…
