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.

 IE Expo China is big exhibition that hold in August in Shanghai China. GN as leader of solids control and waste treatment industry, also attend this exhibition as an exporter. For the past years’ exhibition, there would be many buyer from all over the world in different industries,such as the petroleum, waste water, drilling ,chemical etc. But for this exhibition ,there is less foreign buyer attend due to the COVID-19. Most are the representative purchase and searching equipment for the abroad importer. However we still built good connection with many buyers.

For this exhibition ,GN bring the oil sludge treatment system and decanter centrifuge .This two equipment are very popular in many countries for the past several years.Especially the oil sludge treatment system ,which is main used to separate out the solids,recovery the oil and water from the oil sludge. At begin ,it most used in the oil well field to treat the oil base drilling mud.As we upgrade this system,which is more widely using now, such as the industry waste oil ,waste lube oil and also the biological wast oil. It is truly recovery ,recycling and environment friendly.

We also take the decanter centrifuge to exhibition.As we all know decanter centrifuge is always one feature product of GN. After the several years development ,we have EY,EP,EC these 3 different series of Decanter. EY used to separate the solids and liquid ;EC apply to clarify the liquid ,and EP is dryer the solids .Good price with stable quality ,this is the advantage of us.The exhibited Decanter centrifuge attracted a lot of attention ,because to different industry application, the corresponding model is more specific to get the best effect.

It is exciting to meet so many client on exhibition ,and shared the experience each other. We sincerely invite you to visit us to know more about us.

GN is a equipment manufacture of solids control and waste treatment .At the begin of GN history , we main provide the equipment and service to the oil well drilling company ,such as the shale shaker ,mud cleaner ,shaker screens and also mud system etc .These equipment is main used to treat the drilling mud ,remove the solids from the mud. As long as the development of GN ,we not only serve oil well drilling , but also the other industrious which has the demand of solids-liquid separation. Last week we delivered one drilling mud solids control system for coal mining.

This solids control system has two application. One is clarify the drilling mud that generated in the coal drilling. This system include 2 units GN shale shaker, 1 set GN desander, 1 set GN desilter and also the centrifuge pump. The two sets shale shaker can remove the big particle size that bigger than 60 um. And the pump will transfer the material and feed into the desander . The desander is combination of hydrocycloe and shale shaker. After the desander treatment , will treated by the desilter ,desilter is used to remove more smaller particle. The drilling mud will be clean enough for reuse.

 Except the solids control equipment ,this system also equipped the mud jet mixer. In the drilling program ,sometimes we need to adjust the mud density ,that need to mix some special material with water. This mud jet mixer include the mud hopper and centrifuge pump. This is a high efficiency unit with 45-340 m3/hour. This mud system consider the shipping delivery when make the design ,so the mud tank dimension can be load into container to transfer.

GN can provide the customized proposal for your project. That is our advantage to serve customer ,because different project has the different requirement. If your project has the demand to the solids-liquid separation , welcome to contact us , we will be pleased to share our experience and provide the technical support.

As we all know the decanter centrifuge is one of the most popular equipment of GN. I would like to share the feature of GN decanter centrifuge.

First , decanter centrifuge is one kind machine that easy to wear . we select duplex stainless steel SS2304 and centrifugal casting are used to manufacturing rotating bowl, and shaft for big and small end cap. Duplex stainless steel is stronger and more resistant to abrasion and corrosion. This manufacturing process also avoid intergranular corrosion and incomplete release of stress. Screw blades are manufactured as a whole piece with CNC forming lathe, leading to high accuracy of the blades and higher solids discharge efficiency.

Second,optimized cone and pitch with BD plate to separate dewatering section and settling section, with deeper pond depth, longer dewatering section, dryer solids and clearer water. This also increase throughput speed. BD plate also helps solids discharge.

Third ,Less energy consumption is achieved with bigger pond depth, making decanter centrifuge use less energy. This also reduces turbidity flow of liquid to make separated water clearer, less wear on end blades which makes screw lastlonger.Dual cone angle is available for specific high solid concentration materials. The rotating bowl have two cone angles, which reduced discharge resistance and increase treatment capability while maintaining clarify of water and dryness of solids.

Third, All the rotating parts are made with high accuracy CNC machine. After that 3 step dynamic balancing is done. One is the balancing of rotating assembly at 1800RPM, balancing at real high speed and the balancing of whole machine to ensure stable operation of the decanter centrifuge at high speed.

Fourth,Part of centrifuge select the protected tiles and special design for easily operate and long lifetime .Discharge ports are specially made tungsten carbide with excellent anti-abrasion capability and less fragility;Easy opening mechanism is used so that one man can open the collection box cover for easy access of equipment; Hydraulic removing mechanism is built into main shaft, which reduced pulling force by 90% when removing main bearings, this helps to ensure the safety of the bearing and high precision parts; Both motors are placed in one end of the decanter centrifuges for more service space and spill of slurry to impact service life of motors;Oil lubrication is used to lower bearing temperature and clean bearings;

Fifth, select SKF premium bearing is used for longer service life, and the Real time monitoring of decanter centrifuge’s working condition for overload, bearing temperature, vibration, lubrication pressure, drive currents and screw torque and alarm .

All these feature make GN decanter centrifuge is one kind stable and reliable equipment ,If you want to know more , welcome to contact us.
