As we all know that most equipment are used for the oil gas industry to treat the drilling mud ,especially the Decanter centrifuge ,the decanter centrifuge is one kind high speed centrifuge to separate the small size particle.This year GN built its fourth plant ,which is a big plant and main produce some new products such as the screen bowl decanter centrifuge.

GN screen bowl decanter centrifuge

The screen bowl decanter centrifuge is one kind low speed centrifuge,it is wide applicability  for dewatering of flotation clean coal, medium coal, tail coal, primary slime, cyclone underflow and pipeline coal terminal. The centrifuge bowl assembled by two parts,one part is similar with the bowl of decanter centrifuge,and the other part is screen bowl with hole.The slurry can through these hole under the centrifuge force.And also the filter section of the centrifuge bowl applies high-aluminum ceramic screen mesh, long service life.

GN screen bowl decanter centrifuge

GN screen bowl decanter centrifuge has 5 models, they are SBC900×1800,SBC1100×2600,SBC1200×2000,SBC1400×2000,SBC1600×2400. They are different in the bowl size ,for example the SBC900X1800 means the bowl diameter is 900mm and the length is 1800mm. The more bigger bowl size mean the big capacity. It is 10-100 tons/hour for the different models. As we said it is low speed centrifuge ,the roated speed is only between 600-900rpm. The power is between 110kw-280kw. This screen bowl Decanter centrifuge can separate the Ultrafine Coal the size between 0-0.5mm. The liquid after the screen bowl decanter centrifuge will be feed into the decanter centrifuge for the last step treatment to recycle the coal smaller than 0.5mm and also get the water for reuse. GN screen bowl decanter centrifuge main for the cola mining company, and we have 1 year warranty and good after service ,for the north American customer if you want to know more about this kind product,you can contact GN Solids America LLC, which will reply you soon and send the information what you want.

As we all know GN Solids Control is a famous with his solids control equipment at the global market. GN equipment are widely used for the solids-liquid separation. Most our customer think we only provide equipment to some projects such as oilwell drilling, trenchless ,HDD system, tunnel boring .Actually our equipment also have the good performance at the environment protection . last week we delivered several sets equipment to an international environment company ,and it include shale shaker ,mud cleaner and decanter centrifuge .

Shale shaker

Shale shaker also named vibration screen .It is one kind machine that take advantage of the G force generated by vibration to remove out the solids from the slurry. GN shaker screen select the Italy Oli brand vibration motor with good performance and long lifetime. The shaker body is welded by robot and using the stainless steel . All these strictly control of quality to make sure the shaker will have a good performance to serve customers’ projects .GN shaker have variety capacity from 45m3/hour-120m3/hour , and several shakers can combine into one unit to work together for big capacity.

Mud cleaner add the hydrocyclones based on the shale shaker. Which is used to separate the more smaller size particle not bigger than 1000um. There will be a shale shaker under the hydrocyclone ,the liquid after hydrocyclone will be treated again by this shaker to make sue the liquid more clean before feed into the decanter centrifuge.

Decanter centrifuge

Decanter centrifuge is the last step of the solids-liquid separation. Which main used to separate the particle size smaller than 60um.Under the high rotate speed , which will generate 3000 G force, the water after decanter will clean enough for reusing. And the solids will enough dry to transport and for some other using .The decanter centrifuge is more and more be used for different industries. If you want to know more ,welcome to contact us.

On the fermentation progress the bacteria, yeasts or molds will transform into valuable products and materials. Mechanical separation technology allows these fermentation products to be obtained from the fermentation broth. GN disc centrifuge can be used to separate the fermentation to get the valuable products .

Most times the fermentation material will invlov the water ,oil ,cells debris ,extract material, (sometimes we will use the hexane as the extract material to finish the extraction process .Hexane is one kind explosive material ,so when the material include hexanr or the other explosive material,the disc centrifuge must equip the Nitrogen isolation to prevent the air contact).The valuable products will dissolve in the hexane , the disc centrifuge can separate the water ,solids,hexane in same time ,this progress is efficient and quick . After we complete the separation ,the hexane involved the valuable product will be further separation by distillation. Through the different boiling point ,we can get the final material that we want .

Disc separator

Disc centrifuge has wide application ,not only the fermentation the above we mentioned , but also the pharmacy, winery,chemical, environmental protection etc. According to the different application , it has 2 phase and 3phase centrifuge . The 2 phase centrifuge only  can complete the solids and liquid separation. the 3 phase disc centrifuge can treat 1 solids and 2 kinds liquid as same time . But it require the two kinds liquid with different density and also do not dissolve each other. The disc centrifuge  rotated speed can reach 7000 rpm and the G force can bigger than 10000G, which is high speed centrifuge . The inner bowl used the extra strong and wear-resisting steel. Ever parts are processed by the precision machine tool .Such as the disc also need to past the balance test under the different speed.

Our technical team can provide the professional solution for your project , if you have the demand in the separation equipment , welcome to contact us.

In the last month, GN delivered to the mud recycling system to Singapore. Which be used to treat the mud for tunnel boring. As we all know that GN has the full experience on the solids control industry. Our equipment and system have served many drilling ,trenchless,tunnel boring project .The very famous project is the 5.2km HDD trenchlessproject for Hong Kong Airport, which success set the world's longest record for directional drilling crossing engineering at that time. We are so honored to take part in this project and GN equipment showed the excellent performance to guarantee the success.

 Tunnel Bording Mud System

After we shared these successful case with our Singapore clients. They decide to GN as the supplier to provide the whole set solution of the mud treatment for the tunnel boring project. Frankly,this project is not complex for us and our technical team give out the technical proposal in a short time , and the proposal got the approved by client after small revising .Our full experience and technical support make the project processing runs very quickly.

Tunnerl boring mud system

Last month we shipped the mud recycling system from our plant. It is a system with treatment capacity 1000gpm. We added the decanter centrifuge and chemical dosing unit to the system. The two equipment are used to separate the very small particle.Sometimes the tiny particle is hard to remove ,We have to combine them into the bigger size particle .The chemical dosing can add the flocculant ad mixed with slurry to make the tiny particle bigger. Then material will be feed into the Decanter centrifuge by screw pump ,the solids will be removed under the high centrifuge force generated by the high rotated speeding.

If you also have the project need solids-liquid separation, welcome to contact us . We will be pleased to provide the technical support and also equipment.We will share more things about the Singapore tunnel boring project after project starting.  

Centrifuge is one kind equipment that used for the solids-liquid sepration . It has wide application in different industrious ,such as the energy, chemicals, pharmaceuticals and so on.Through the high rotated speed ,the solids and liquid contain in the material will be separated.Higher density solids will sink to the bottom and lower density liquid will be on the top layer.This is the centrifuge principal of separate. According to the different G force ,the centrifuge can be classed into low speed and high speed .Such as the Disc centrifuge belong the high speed and G force bigger than 10000G. Under such the big G force ,even the material with little different density can be separated, so the Disc centrifuge is mainly used to extract some material,such as protein,chemical etc.But we should noticed that the solids content of feeding material should less than 3%.

solids-liquid separation

In most time, we will use decanter centrifuge to separate the material first, Which is one kind low speed centrifuge,the G force between 2000 to 3000 G,the feature is that decanter centrifuge can treat the material with 20% solids content. Most of the particle between 2-5um will be separate under this G force.So it is good choose to treat material firstly between feed into disc centrifuge.

solids-liquid separation

When we select the centrifuge model, we should know some data about the material. Such as the solids content, the particle size,the treating capacity, then we can know which model is suitable. Sometimes we also need the other flocculant to assist to get the separation purpose,the flocculant can combine the tiny solids into bigger and convince to separate. For some separation project ,which is a complex process, which need a whole set solution. GN solids control has the full experience of separation on the drilling mud,waste water treatment,mining slurry,soil remediation etc. If you have these demand, welcome to contact us.
