GN Solids Control has been working on manufacturing the best decanter centrifuges for many years. GN Solids Control centrifuges are widely used in oil and gas area for solids control and drilling waste management.
Now GN Solids Control manufacture 350 sets to 500 sets decanter centrifuges every year, over 70% are using globally. As one of the branch company of GN Solids Control, GN Solids America has been providing decanter centrifuges for many years, some other solids and liquid separation equipment such as shale shaker, mud cleaner, destiler and desander etc are also provided.
GN Solids Control decanter centrifuges are largely using in oil and gas area, but these years in the other slurry treating area, GN Solids Control centrifuge also play well.
Several weeks ago, GN Solids America delivered one 14 inch size bowl centrifuge to one USA customer. This set centrifuge will be used to treat the drilling mud or drilling slurry.
GN Solids Control has 5 size decanter centrifuges include 9inch baby centrifuge (mainly using in diamond drilling, core drilling or mining slurry treating), 14inch centrifuge, 18 inch centrifuge and 22inch centrifuge (among which the 14inch centrifuge are the most popular one in solids control and waste management area although the other sizes are also used), as well as GN largest size decanter centrifuge 30inch rotating bowl (mainly using in TBM drilling area).
The one we provide is one 14inch size GN centrifuge, model GNLW363, equipped with one VFD control box. GN centrifuge rotating bowl is made of duplex stainless steel by centrifugal casting, and inside the screw conveyor is fixed with hundred pieces of tungsten carbide tiles which can be replaced when broken.
GN Solids also provided one stand to equip this decanter centrifuge, and one feeding pump is fixed on the skid to pump slurry into GN centrifuge. GN Solids Control only uses high quality products, such as the pump we are using is Germany brand Netzsch. While the two main bearing is SKF bearing.

GN Solids Control is only devoted to provide consistent quality shaker screens to suit different site usage, no matter it's oil and gas or HDD etc. We DO not want to cut our manufacturing cost by using some cheap raw materials.
1. Screen Frame:
As you know the composite screen is embedded by one metal screen supporting frame. Many screen vendors are using single layer and less metal bars, which are OK in some worksites usage but will also broke shortly in the other sites.
2. Composite Materials:
There are 3 popular ways to get those composite or plastic for all composite screen manufacturers: a. Recycle and reuse second hand plastic; b. Buy chemicals and manufacture by himself; c. Buy high quality prilling plastic.
GN only uses the last one which is high quality prilling plastic, obvious this is the most expensive one, but the composite frame is also last longest.
3. Wire Cloth:
Different screen manufactures are buying from different wire cloth vendors, top rank, second rank and third rank... GN Solids only use top rank wire cloth which is the same vendor as Derrick and Mi-Swaco.
Different wire cloth to from the API no., GN only uses 304 for the bottom layer, but use 316L for the middle and top layer.
4. Injecting Moulding Machine
GN has its own injecting moulding machine. Quality can be controlled strictly.
Consistent quality is very important for us, we will never manufacture screens that work well in one site and fail in the other site. Quality is one thing; the API cut point is another important thing to consider.
As far as we know, GN is the only China Screen manufacturer has all the API no. that tested by a USA third party in order to conforms with API RP 13C. You may double check with the other China screen vendors whether they have a full series API test report issued by a third party.
Besides, GN Screen are 4 side tensioned, it takes time to do this (actually manufacturing efficiency is pretty low) and also waste some screen cloth during manufacturing but it's totally worth. We can send you a tension testing tool next time so you may check whether the other screen vendors are using any pretention method.

GN Solids Control HDD mud recycling system helps Hong Kong Airport to stock airplane oil. Last year, GN Solids Control provides one set of 1500GPM mud recycling system to one Hong Kong HDD construction company. They use GN Solids HDD mud recycling system to treat the mud during HDD machine working.
The Hong Kong Airport oil stock project is pretty complicated, it was meant to build one undersea pipe to connect with the airplane. During the HDD working, the local government asked not to pollute the water and make any effect the natural environment. This is one the largest reason that GN Solids Control HDD mud recycling system is used.
This HDD mud recycling system is composed by 2 sets 1000GPM mud systems, it includes the following treating equipment:
1. GN Shaker
Each 1000 GPM mud system is fixed with 2 sets shale shakers. GN Solids Control also manufactures shakers screens for GN shakers. GN Solids Control is using GN made shaker screens. GN Composite Frame shaker screens are much more cost-effective than traditional metal frame shaker screens. GN Solids America LLC also has over 6000 pieces screens.
2. GN Desilter
GN desilter is the shaker fixed with 4inch hydroclones.
3. GN Mud Tank
All GN shakers and GN desilters are fixed on the top of mud tank. GN desilters feeding centrifugal pumps are also located on the side of the mud tank.
4. GN Screw Conveyor
Between these 2 mud tanks there is one screw converyor, which is used to collect all the solids discharged from shakers and desilters.
GN Solids Control mud recycling systems helped the Hong Kong HDD project work successfully and also protect the environment.
Now GN Solids Control has many sets of shakers, desilters, mud cleaners and decanter centrifuges stocking in Houston warehouse. Welcome to check these solids control system in Houston, USA. GN Solids Control is good at providing turnkey solutions.

GN Solids Control product line covers all the most used treating equipment like shale shaker, desander, desilter, mud cleaner, centrifuge, cuttings dryer. GN Solids Control is especially good at providing turn-key solutions for solids control and waste management systems.
Oil and Gas industry is one of the largest one for GN. While these years, GN Solids Control also working on to providing mud/ slurry treating systems to some other industries such as HDD, Mining, Diamond Drilling etc. Last week, GN Solids Control just delivered another shaker for one USA construction client.
GN Solids Control manufactures shale shaker, 10 inch desander treating equipment, 4inch desilter treating equipment as well as mud cleaner. Besides those above standard treating equipment, GN Solids Control also provides turnkey solutions, such as 200GPM mud system, 500GPM mud system and 1000GPM mud system.
Usually shaker is located on the top of one mud tank. For this USA construction client, they have some tanks in their site so we can only provide the shaker and shaker screens.
GN Solids Control shale shaker is only using 2 brands vibration motors: one is USA Martin and he other is Italy OLI. All the shakers delivered to USA are just shaker deck without any motors. GN Solids America will assembly USA made vibrators in USA and do some testing before deliver to customers.
This is one 4 panels shaker that GN Solids Control provided. G force up to 8.0G or 7.5 G. It’s especially good at separating water based sludge. When you choose different API nos. shaker screens, you will have different particles separated out.
Actually, the largest advantage to use GN shakers is GN Solids Control provides the most cost-effective shaker screens. GN Solids Control has over 6000 pieces screens stocking in Houston. GN Screens now has been providing to over 72 countries and regions.
