decanter centrifuge

GN Solids Control is one of the largest solids control and waste management companies specializing in the production of related equipment such as shale shakers, desanders, desilters, mud cleaners, vacuum degassers, mud gas separators, sedimentation centrifuges Machine, agitator, centrifugal pump, cutting dryer, screw pump, shear pump, mud gun, etc. After 10 years of development, GN has promoted its products to more than 60 countries and now has two overseas subsidiaries in the US and Russia.

Recently, we forced our key staff to push our Decant centrifuges to the North American market. So far, we have received a lot of good feedback from different end users in the US and Canada. Our decanter centrifuge system is suitable for many different environments. They can work in a super hot desert environment. The VFD control system is provided by SIEMENS or ABB. All bearings used in the centrifuge are made of SFK quality bearings to ensure longer life and more reliable operation. All motors and control panels are explosion-proof and certified for use in Zone 1 and Zone 2 hazardous areas. The 553 decanter centrifuge will be a star product for handling large volumes of liquid and solids separation work. More and more customers are showing great interest in this. Also for many different industries, they also chose our decanter centrifuge as the first choice for solids separation. Now GN can not only manufacture the traditional 363 centrifuge with a 14-inch bowl, but also make a larger bowl size GNLW553 with a bowl size of 22 inches. The equipment can be used to process water-based mud, oil-based mud systems, dewatering and recovery of barite. This device also has some great features: it is VFD controlled and offers operators a variety of solutions to adapt to changing field operations.

This is a basic introduction to the large bowl type decanter centrifuge 553. I hope it will be useful to you. We will do our best to help your business succeed. Welcome to www.gnsolidsamerica.com and send your questions to USA@gnsolidscontrol.com

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.
