Recently, GN Solids Control finished the production of the first batch of shale shakers and mud cleaners for a China drilling company. With the HSE requirement for the drilling site, customer are looking for cleaning job site. The specially designed shale shaker with spill proof cover is convenient for client to keep a clean jobsite.

The total contract is for two drilling rigs, the supply scope include 6 sets GNZS595J shale shaker and 2 sets GNZJ594J-3S16N mud cleaner and 2 vacuum degasser.

The Spill Proof cover for the shale shaker is stainless steel material, and the special design makes it convenient to open and close for inspection of the drilling fluids treatment. Since the angle of the shale shaker will adjust according to the drilling conditions. The Spill Proof Cover will adjust synchronously with the shale shaker. Another function of the spill proof cover shale shaker is to control the vaporization of liquid to reduce the smell.

GN Solids Control not only provide traditional shale shakers, but also provide the Vacuum Screen technology for shale shaker to enhance the drilling fluids recovery.

GN Solids Control last week finished one batch of 4 sets 9 inch bowl centrifuges for one European core drilling company, very soon they will be shipped to customer and GN will have another happy customer as well.

GN Solids Control has been designing and manufacturing decanter centrifuges for decades by professional engineers who have deep understanding and also rich onsite experiences. Every year, GN Solids Control manufactures around 60 sets 9 inch bowl decanter centrifuges, most of them are used in core drilling or diamond drilling industry, and some are used for small scale lab volume treating and testing. 

GN Solids made 9 inch bowl centrifuge is also called GN baby centrifuge as it is the smallest bowl centrifuge we build. The bowl is duplex stainless steel made by centrifugal casting, and protected by tungsten inserts and scrapers for long time anti weariness. GN Solids Control centrifuge is also optional to fix with temperature sensors and vibration switches so the two main bearing blocks’ temperature and the centrifuge vibration can be monitored on GN HMI control panel.

As for these 4 sets GN 9 inch bowl centrifuges, GN Solids Control provides a compact mud stand to fix the centrifuge with a certain height skids. After separated liquid can be stored in the bottom mud tank easily.

These 4 sets centrifuges are all fixed speed electric driven units, drilling company will provide a diesel generator to provide power. All systems are designed and build in a compact manner, convenient to move and relocate with the drilling rig.

Besides these 9 inch bowl centrifuges, GN Solids Control also manufactures bigger bowl centrifuges, such as 14 inch, 18 inch , 22 inch and 30 inch. Different bowl centrifuges are widely used in different industries. Please feel free to connect with GN Solids Control for any centrifuge inquiries.

GN Solids Control is a world leading manufacturer of solids and liquids separation equipment and turnkey solution provider, one of the most typical product for GN is shale shaker which are largely used in thousands of drilling rigs sites. These days, GN Solids Control engineers finished the upgrading and testing of the new J version solids control shale shaker, and some sets have already been delivered to GN overseas customers.

Shale shaker is the first treating equipment when we speaks of large particles remove, by fixed with different cut points screens from API 10 to API 325, GN shake shaker is able remove solids in large variety range.

Compared to the previous version of GN shale shakers, here are the main advantages for the J version shaker:

1.Patent structure of sealing rubber on the shaker deck, excellent anti-weariness, longer using life but more convenient to replace.

2.Convenient to assemble optional anti-spraying device on shale shaker and mud cleaner.

3.Convenient to modify to vacuum screens unit by adding GN ViST.

4.Much easier to adjust the shaker deck working angle, and fast lock after adjusted.

5.Stainless steel shaker deck supporting beam, last longer when using for offshore drilling rigs.

6.High strength vibration spring, excellent working performance with long using life.

GN Solids Control now manufactures around 250 sets to 350 sets shale shakers every year, most of them are using in oil and gas industries, and some are used on environmental protection industries, such as hydrovc slurry dewatering, mining slurry dewatering, diamond/core drilling mud recovery etc.

Besides the shale shakers, GN Solids Control also builds some other solids and liquid separation equipment such as decanter centrifuge, cuttings dryer and transfer units like screw conveyors, solids transfer pumps, screw pumps etc. GN experienced engineers are able to provide the most cost-effective solution for your solids and liquid slurry treating.

GN Solids Control is a leading construction mud treatment system provider with customers from over 85 countries and regions. Several weeks ago, GN engineer visited one Australian construction company and got a very positive feedback on the GN mining vibrating screen and decanter centrifuge’s excellent working performance.

1.GN Mining Vibrating Screen

GN Solids Control manufactures different types of vibrating screens, such as dewatering screen, classification screen, stack vibrating screen, large linear vibrating screen, large banana vibrating screen etc.

GN Solids provides one sets of dewatering vibrating screen for this Australian construction company who owns more than 20 sets hydrovac trucks that can bring min. 100 tons slurry or waste from different sites.

This vibrating screen is especially designed to remove big particles larger than 2 mm before feeding into GN fine shaker unit (includes a double deck fine shaker and a desilter). A big catch hopper is able to collect two hydrovac trucks to dump at the same time, and a manual control gate valve to adjust the dump feeding volume into the big vibrating screen.

2.GN Decanter Centrifuge

GN decanter centrifuge is especially designed to remove the finest particles from the hydrovac slurry, with a big G force upto 3000 G, silts larger than 2~5 microns can b recovered.

As for this construction company, GN Solids Control provides one 22 inch bowl decanter centrifuge, which is able to treat at least 30 m3/h slurry with 20 % solids content. To help the centrifuge use a long time without weariness, GN Solids Control use tungsten scrapers and inserts to protect the solids discharge ends. Optional flushing lines can be also built on the centrifuge’s collect box to flush the solids discharge ends and reduce the solids abrasion.

GN Solids Control has rich experience to provide solids and liquid separation for varieties industries, welcome to reach to GN for the most cost-effective solution.

 GN Solid Control is a top brand solids and liquid separation as well as conveying equipment manufacturer based in China with 3 manufacturing plants includes 2 close to Beijing International Airport. Last week GN Solids Control shipped another batch of waste sludge treating equipment to one Asian client. 
 
As we all know that sludge is hard to move after sediment especially when it has been stocked for many days, while GN Solids Control has one sludge transfer pump which is the vacuum pump that can move all high solids content and large viscosity materials. 
GN vacuum pump is an air driven united, during work it is connected with an air compressor. As long as the solids size is smaller than the feeding port, it can be moved by GN vacuum pump, such as aggregates, oil sludge, chemical powers etc. 
GN Solids Control uses one 40B vacuum pump to suck the sludge from the waste pit and dilute it with water before feeding into GN decanter centrifuge as usually solids less then 20% can be treated. And another point we need to consider is in order to have a better and consistent treating performance that an even materials is ideal to feed into centrifuge. 
 
GN Solids Control has been provided thousands of decanter centrifuges in the world, especially in the oil and gas industry for the drilling mud solids control and drilling waste management area. GN Solids Control also builds environmental protection centrifuges with different half cone angles, length and diameter rates etc to achieve the dewatering, clarfiying and thickening treating demands. 
Usually centrifuge is feed by a screw pump, so the feeding flow rate is linear and can be also adjusted easily on the HMI of the VFD box. Welcome to connect with GN Solids Control, here we always have the right cost-effective solution for you.

GN Solids Control just shipped to a offshore drilling company of 18 inch bowl decanter centrifuge and mud agitators last week. As we all know, GN Solids Control provides both on shore and offshore drilling mud solids control equipment and waste management systems, with these years fast development, GN Solids Control becomes one of the most cost-effective solids control and waste management equipment provider in the world.  

GN Solids Control made decanter centrifuges has been widely used in more than 85 countries and regions, especially using in oil and gas industry although GN centrifuges are also used in environmental protection industry. Usually offshore drilling platform demands much higher standard when use the drilling solids control system and drilling waste management systems, such as all the equipment should be designed and manufactured according to DNV standard. 
GN offshore drilling mud solids control decanter centrifuge is fixed with DNV lifting certificated skid to protect the centrifuge from falling off into the sea. Here GN Solids Control shipped one set 18 inch bowl decanter centrifuge, beside 18 inch GN Solids Control also manufactures 14 inch and 22 inch bowl centrifuges for the drilling mud solids control and drilling waste management. 
 
Drilling mud is very important in the offshore drilling platform, one main function is to keep the drilling rig function well. However to reduce the drilling cuttings or reuse the drilling mud is also very important, as shipping cost is huge for large volume transporting. Use decanter centrifuge to recover effective drilling mud with 2-5 microns and dewater the drilling cuttings is the main target. 
Besides the drilling mud decanter centrifuge, GN Solids Control also shipped some sets of heavy duty mud agitators to this offshore drilling rig. All mud agitators are fixed with lifting pad eyes for offshore movement. 
 
Welcome to connect with GN Sales Engineers for your drilling mud solids control and drilling waste management demands, we always have the right solution for you.
