Recently GN solids control start to apply our decanter centrifuge for industries except for oil & gas drilling, constructions industry, for example, industry waste water treatment, oil tank bottom cleaning, solids waste treatment, etc.
GNLW553C-VFD big bowl decanter centrifuge with dosing system can be used for industry waste water treatment. We have 3 models decanter centrifuges can be used together with dosing system. GNLW363CG-VFD is with 14inch bowl decanter centrifuge, which is the most popular model. GNLW453C-VFD is the 18 inch bowl decanter centrifuge, it is the middle model. GNLW553C-VFD is with 22 inch diameter big bowl which is the biggest model decanter centrifuge.

The dosing system is installed inside a 20ft container, with lights, windows, doors, air conditioner, etc, for convenient operation and transportation. To reduce the total cost of the dosing system, the dosing system with only a polyurethane material mixing tank and 2 dosing pump with electric control panel. The VFD control panel is not same configuration with oilfield explosion proof VFD control panel, it is a low cost special designed for non explosion proof applications, for example, TBM, dredging slurry separation, sewage water treatment, etc. The non exploson proof VFD control panel is also PLC smart control and touch screen, but the cover is not full of stainless steel material.

GN Solids America LLC is one of the top machinery manufacture in China for drilling mud solids control and drilling waste management of the drilling cutting waste.  The shale shaker screen is most consumable part on whole drilling mud solids control process.  GN solids America’s shale shaker screen combine with exceed industry standard and aggressive sale price, it becomes most selling item among operators in the drilling field that perform drilling and/or waste management for environment protections.

GN Solids America LLC manufacture replacement screen for popular brands like Derrick, M I Swaco, NOV and Fluid System.  GN Solids America LLC also accept custom design order for screen as well among other brands and operators that have special need for operation.  While price and spec is exceed expectations of operators, GN Solids America LLC offer 2 type of frame materials for the shale shaker screen to satisfy operator’s operation objective.  Steel frame shale shaker screen is for price awareness operator while composite material frame shale shaker screen is for operation-effectiveness operator.  Both type of screen will filter the same index of solids that is in the drilling mud and/or other wastes.  . Composite material screen has better separating performance due to the shaker screen area is larger than metal frame screens. The steel frame shaker screens are very heavier while the price is lower than composite material screen.

GN solids America LLC’s main replacement shale shaker screen is for GN Solids America’s own shale shaker and mud cleaner and for M I Swaco’s Mongoose shale shaker.  The screen has offer both metal frame and composite material. Generally speaking, the using life of composite screen also last longer than the metal frame screens. GN’s replacement for NOV King Cobra series and  VSM-300 series screens also has those two materials can be chose. All shale shaker screen comply with the manufacturing standard of API RP13C, which the common standard for separating measurement.

As one of the most professional solids control and drilling waste management equipment for oil & gas drilling, we use a lot of electric control panels for our equipments, also for the drilling solids control system and HDD & CBM mud recycling system, even for the pressurized VFD control panel for the decanter centrifuge and vertical cuttings dryer. The delivery time, quality and design from the precious supplier( the top explosion proof control panel manufacturer in China )can not meet our high standard for our international client which should comply with our advanced equipments’ design, so we start a new workshop to produce our own electric control enclosures which with higher standard, better material, faster delivery time and user friendly design, especially for the electric components inside the explosion proof enclosures, we use world famous brand like ABB, Siemens, Schneider.

Actually we start to produce GN solids control own brand electric control panel and positive pressurized VFD control panel several years ago, GN produced VFD control panel for decanter centrifuge and vertical G dryer with the features below:
1) 100% stainless steel material cabinet with 3 motor VFD( main motor, back drive motor and pump motor), sometimes we produce carbon steel material VFD control panel when the client required a cheaper unit because of their budget
2) World famous electric components, the client can replace the part locally, like
ABB, Siemens, Schneider.
3) Pressurized VFD control panel instead of normal Chinese explosion proof control panel for better cooling and performance under high temperature, air conditioner is for option for extremely hot area as the client’s special request
4) PLC smart control with touch screen, HIM automatically control the frequency, speed, differential speed, etc.

5) Compact design, container shipment, telescopic skid is available to install the VFD control panel with the centrifuge in the same skid for convenient transportation.

All drilling functions are similar in some aspect such as drilling when one is re-decorating the house and laying the actual pipelines for the water along with electricity inside home, we all use a drill and utilize water as media. The particular function of the water the following is to protect the drill bet and when the water is out, the particular some particles from the wall structure come out with the water. Of course , all of us don’t need to reuse the little amount of water and just remove the dirt away.
To get other drilling projects resemble, just a little bit or more complicated. As the earth’s composition is more complex than the wall and much more hazardous, so when drilling for the gas and oil wells to a certain depth, there has to be professional engineers to make the drilling mud as drilling growing media according to the earth condition plus the mud must be treated well, as well as economically after use in in an attempt to be ready for reuse.

GN Solids Control focuses on providing for those drilling projects the mud cleaning systems including:
one Oil and gas drilling mud systems including all 5 various phases separation, 4 actions solids control, with major equipment like shake shaker, desander, desilter, vacuum degasser, centrifugal pumps, submersible slurry pumps, shear pumps and also mixing hoppers, and also the decanter centrifuge and vertical cuttings dryer. In all, the complete brand for oil and gas solids control.
2 . Mud recycling devices for HDD and CBM. HDD and CBM drillings are also drilling works, the functional principal is similar. Comparing together with oil and gas drilling, HDD jobs need less equipment although comparing with other drillings, HDD need more. GN has typical designs for HDD drillings for different treating capacities.
a few. Other drillings and building works like TBM, h2o well drillings and mining or prospecting.
May you need more information or even need some suggestion for selecting suitable mud recycling system, pls contact GN to find out more.

As we all know, GN decanter centrifuge mainly used for drilling fluids/ mud treatment in the past years, we are developing our centrifuge for other different applications, the new applications are as below:

Dewatering sludges / mud and suspensions
Thickening sludges or mud
Clarifying different type liquids
Separating 3-phase mixtures, i.e. two immiscible fluid phases and a solid phase
Classifying solids in a wet suspension by grain size
Separation of solids according to various densities
Our decanter centrifuges can be used for both oil & gas drilling mud and none oil drilling mud, the function is to separate solids from the liquids, to keep the drilling fluids balanced, and reuse the drilling fluids to prepare for new drilling mud.
According to client’s feedback at oilfield rigsite for drilling waste management, GN decanter centrifuge can help them to reduce the water content efficiently from the drilling cuttings discharge, and reduce the fine solids from the drilling fluids ( mixed with water and oil), the next treatment step is oil water separator. The separation cut point is up to 2 microns, and after using the dewatering unit together, the cut point is up to 1 microns. Our decanter centrifuge is also used to barite recovery at low speed 1800~ 2200rpm, and low gravity drilling fluids at high speed 2700 rpm~ 3200rpm, and dewatering unit at 3200 rpm ~3900rpm.
