GN has focused on the solids-liquid separation for more than 15 years. At the beginning of GN, we main provide the service to the oil-gas company ,mud slurry company to treat the drilling mud, and we produce the equipment for our customer, such as the decanter centrifuge,shale shaker. Most of our before equipment is used for the 2 phases separation. But for some project, which require the 3 phases separation for the oil,water,solids. With the client requirement ,we produce the 3 phase decanter centrifuge by ourselves.

The 3 phase decanter centrifuge utilized the same principle. The different density material will separate into different layers under the force that generated by the high rotated speed. The solids will be on the bottom layer, the water stay on the middle layer, and the water in on the top layer. Solids and water are same way to discharge, but the oil will be pumped by a centripetalpump. According to the capacity ,GN Decanter centrifuge have 5m3,10m3 and 15m3 the 3 different models. The biggest rotated speed can reach 300 RPM can generate 3060G force. All different model are driven by VFD, the rotated speed is adjustable.

GN decanter centrifuge has lots of feature. As we all know the screw sclloper is very easy to wear under the touching with material with the high rotated speed. GN select tungsten carbon tile to bolt on the screw for the long life time ,even the tile is consumed, it is very easy to take down and you just to replace the broken part ,because it bolted installing. The rotated bowl are passed 3 times for the balanced test to make sure the perfect work performance. And also the material choose the SS306 for more longer life time.

GN 3 phase decanter centrifuge can be used on many different industries, the oil sludge treatment ,the kitchen waste treatment, the chemical material extraction etc. If your project have the demand on the 3 phase separation, welcome to contact us , we will be pleased to share our experience and provide the equipment for your project.

GN was found in 2005, with the 15 years development, GN was famous in his solids control equipment. And we also develop some equipment with new technology and used to improve the efficiency of drilling. In the oil well drilling and some other project such as the HDD,tunnel boring,pipe jack. The drilling mud is very expensive and also high polluted. So we always try to recovery the drilling mud as much as possible.In the drilling treatment ,the shale shaker is the most important and widely used to treat the slurry, but the normal shaker only can roughly separate, the discharged solids still include lot of drilling mud ,which is a waste, and also improve the cost of drilling slurry.

GN VIST is one kind auxiliaryequipment of shale shaker, which main used to increase the shaker working performance to dryer the solids and recover more drilling mud. VIST is driven by air ,so it can be used in every area even request the high explosion proof level. As we just said VIST utilize the air pressure to suck the liquid that included in the solids and recover it. There will be a catch pan installed under the screens,when start the VIST unit ,the space between screens and catch pan will generate the negative pressure. When the material flow on the screen ,the negative pressure can suck the liquid through the screen and be collected by the catch pan.

According to our test and using report from our customer ,the shaker equipped with VIST , which can recover more 30%-40% slurry, and the solids is also more dryer. The VIST can fit under most shaker models in the market , and one unit can match with 3 sets shale shaker. It need 4.5m3/min air supply with 0.7-1.0 Mpa pressure. The pressure and air flow can be adjusted according to actual situation.

VIST is a high efficient equipment to reduce the waste of slurry , if you want to know more ,welcome to contact us. We will be pleased to share more the information.

After 15 years development ,GN not only serve the oil well drilling ,but also provide equipment to the waste water plant. Actually the drilling mud and waste water treatment both are remove the big size solids and recycle the liquid. GN P series decanter centrifuge is specially used for the wast water treatment. Last week we delivered the GN 554 Decanter centrifuge to UK, and also the screw conveyor for the solids conveying.

GN 554 Decanter centrifuge is the second large capacity equipment, which has served many project of all the word ,oil well drilling mud treatment , waste water treatment ,and also in some chemical industry. 554 Decanter centrifuge is driven by VFD, the max rotated speed can be 3150 RPM , and max G force is 3051G. The bowl diameter is 22 inch and the length is 91 inch. The longer bowl can keep the material staying more time is the screw bowl , then the solids-liquid can be separated more better .GN used many special material to the centrifuge, such as the bowl is whole body cast with SS316 steel, it is more stronger. The screw used the anti wear material Tungsten Carbide Tiles, which makes the screw work for more longer life, and the tiles are installed by bolt ,it is very convenient to repair and replace. Some our competitor weld the anti wear material on the screw, so it have repair the whole set screw ,even part of the screw was damaged.

As the request customer , we produced the screw conveyor for customer’s project. This conveyor is combine with sever sections, each section is same diameter and they can connect together into a more longer conveyor. Which is really good idea for the shipping. Because it will hard to transport if the conveyor length is longer than container.

GN has the rich experience in the solids -liquid separation project , if your have the similar demanded, we will be pleased to share our experience and provide the technical support.

As we all know that many China city have more and more strictly requirement to the environment protection ,especially in the program of some municipal projects ,such as the treachless ,tunnel boring for subway etc... The treachless are more and more widely used in some project such as the municipal cable laying, sewer line of city ,but it also will custom large water and generate the sludge . As normal these sludge is forbidden to directly discharge and hard to transport because the liquidity. GN mud desander is specially used to treat these sludge . Last week we delivered 4 sets desander for trenchless project of China.

This desander is combine with hydrocyclone and shale shaker ,which capacity is 500GPM and it round 115 m3/hour. This is high efficiency simply system. From the picture you can see we equipped the centrifuge pump and mud tank. The sludge will be feed into the hydrocyclone first , and it will remove the big particle sand , then the solids will be discharged from the bottom of cyclone .and through the shale shaker treatment ,which would be further dewatering .The solids will be more dryer ,so these solids is more convenient to transport . the most important is the liquid can be recycle for the treachless again to reduce the cost of water.

GN drilling desander is a feature equipment of GN .We used the plasma cutting to make sure every steel plate notch is more smooth with high precision. 90% welding is finished by robot ,the structure are more strength .For the vibration ,we choose the Italy Oly brand or USA Marin ,both are famous vibration motor manufacture. All these quality control measures make the equipment can win most the complex situation project and high efficiency. If your project have demand in these equipment , welcome to contact us , and we will be pleased to share our experience with you.
