decanter centrifuge

GN Solids Control is a comprehensive company which specializes in manufacturing solid control equipment and system. Since its establishment in 2007, it always focused on the quality and reliability, and how to help the customers save more money. And among all the solid control equipment, there are 3 star products that have been proved to be more rugged, durable and reliable, they are: shale shaker, decanter centrifuge and cutting dryer.

Today I want to talk about one of our best seller—-363 decant centrifuges. Its bowl diameter is 360mm which equals to 14 inch, and it is one of the most popular sizes centrifuges used in Oil and Gas industry. More and more drilling companies started to outsource the mud cleaning services to mud service company, and centrifuge technology is the newest intervention. All the configuration is high standard which can meet most of the customer’s requirement. The bowl material is made of duplex SS 2205/ SS 2304, the screw conveyor material is made of SS 304/ SS 315 and then the surface is protected by the tungsten carbide tiles which is more endurable and reliable, and it can save customer’s money both in operation and maintenance. And the solid discharge port is also used the tungsten carbide inserts. The bearing is still used the world famous SKF. The FHD system is VISCOTHERM full hydraulic drive. The electrical control system is smart PLC control. And the coating is used the Cosco & Kansai Zinc Rich Epoxy Coating. The equipment can be used in extreme high temperature environment with heavy mud situation. And the decanter is designed and assembled on a skid, which makes it easier to move and save time and cost for transportation.

That’s the brief introduction about GN’s new fully hydraulic drive decanter centrifuge. Welcome to visit www.gnsolidsamerica.com and please send your inquiries to USA@gnsolidscontrol.com

As a drilling fluids cleaning decanter centrifuge manufacturer in China, GN solids control keep improving the quality and design of our decanter centrifuge to meet the requirement for different clients and different applications. GN solids control brand is the top brand for solids control drilling fluids recovery, oil sludge treatment, oil recovery, drilling cuttings management. We can meet the different requirement for customized voltage and frequency, and explosion proof standard, like IEC EX, ATEX, CNEX for class 1 div 1.

We can produce 9 inch, 14 inch, 18 inch, 22 inch, 30 inch decanter centrifuge, VFD decanter centrifuge is suitable for drilling waste management system, because the drilling fluids conditions are changing all the time, you have to use different frequency to change the differential speed and pump flow rate to keep the centrifuge working smoothly.

GN solids control second new facility with high advanced workshop to produce decanter centrifuge and vertical cuttings dryer, we owns balancing machine for middle speed, high speed, big bowl centrifuge high speed for different size decanter centrifuge.

The CNC machines can produce centrifuge bowl components by ourselves, the bowl material is centrifugal casting by duplex stainless steel 2304, better than stainless steel 316L, 304. The screw conveyor is made of SS304, the impeller opening is help to improve the treating capacity effectively. The tungsten carbide tiles can protect the centrifuge impeller from danaged, and it is repairable while it is broken.

The bowl lifting bracket is to protect the bearing during road transportation and sea freight, which is the most important and expensive parts for the whole centrifuge.

The important important issue for the decanter centrifuge working life is the centrifuge bowl assy, welcome to visit GN solids control centrifuge workshop to watch the production process of our decanter centrifuge, the faclity is located in Beijing, about 30 km from Beijing Airport.

This is a quite popular design, with a scalping shaker, and a decanter centrifuge for the real separation. More and more clients comes to us for this sort of set up, not only we have the best decanter centrifuge, also the design is quite applicable for many didferent purpose.
Tank cleaning, tunneling sludge treatment, pipe jacking slurry recycling etc.
The basic componets including below:
1)    High G Drying shale shakers
2)    Chemical Dosing System
3)   Decanter Centrifuge
4)    Skid Mounted Mud Tank
5)    Feeding Pumps and transfer pumps.
 
The principle is simple, with old logic, separate them step by step, scapling shaker is  high Dryer shaker is with G force up to 8.0 G, and the 4 panel shaker screens with composite frame increase the conductance and performance.
Then the high speed GN popular decanter centrifuge. GN decanter centrifuge and feed pump is VFD drive which is capable to adjust bowl speed, differential speed, and pump feeding capacity. This allows the operators to select the best parameters for the treatment of different density of drilling fluids.
 
This system is designe for easier transportation, 40ft length, height in the road limit. equipment easy to be disassembled if needed. A step lower design keep this trouble less than you expected.
Various Waste
Now China is like old UK, we got many problems with coal usage, we knew it, trust me, we knew it, and still, we are on the old track, having the same problem, maybe not a tragedy yet, but close.
For environment problems, we need to handle much more than coal, different pollution comes to us before we realized it was our price for developing.
And we never realized that when we did it, at least we never thought it was a problem.

Lucky now we know, now we wake up, in the smoke, we are trying to repair, find solution for the damaged planet. The biggest job we can handle is not so related to air pollution, or water pollution, it is part of them, and fortunatly we are part of it.
This time a client comes to us, need to separate the waste, even for this project, waste from different place. With differnt size particles.
Solutions From GN
When we analyse the site waste, from pictures, samples, we decided to use a system, which contains a shale shaker, and a decanter centrifuge. Shale shaker for dispose most of the big ones, then centrifuges with foluccent maybe, maybe not, to separate the small ones, to reuse water at the same time.
About This System
For thic specific project, we are using GNZS594E shale shaker, with G force upto 7, and armed with composite material screens to increase the equipment life time. For the centrifuge, we are using most popular model GNLW363CG-VFD, SS2205, tungstun carbide tiles screw etc.
This same logic is widely open sourced, can be extend to different similar ideas, different shaker, different centriruge, also work.
If you have some good products like them, and have a little lower price, I mean not a big price gap but not in good equipment condition, quality, you will have perfect market. A lot of clients keep telling us this same story, and that is how it works, when you have a good product, and fair price, it works.
1)    GN Solids Control build the decanter centrifuge with best material for not only performance but also durability. The bowl of the decanter centrifuge is Duplex stainless steel made from centrifugal casting. The screw inside the bowl is made from Stainless steel with reparable Tungsten carbide tiles for protection.

2)    High Speed and good balance: Because we use the most advanced CNC machines to process the parts for the centrifuge, and also GN is one of the few companies who has 3 stage balancing technology, include middle speed dynamic balance at 1800RPM and high speed dynamic balance at exactly the centrifuge operation speed.
3)    Cost effective, we never make the lowest price centrifuge
GNLW363CG is most popular model of centrifuge for drilling fluids solids control. Every year, GN make over 100 sets of the 14inch decanter centrifuge for the oilfield solids control and waste management. GN Solid Control just complete several solids control decanter centrifuge with feed pumps for Latin America oilfield Service Company. Those centrifuges are the GNLW363CG premium decanter centrifuge with 14 inch bowl. The speed of the GN 14 inch decanter centrifuge is up to 3900RPM, normally is 3200RPM for drilling fluids solids control.
This time one client from Latin America purchased 2 units centrifuge, for solids control. We keep many centrifuges in stock, which make the delivery time very short even with the nearly 2 month sea shipping.
