Solids Control Equipment to India

Our business have been driven by repeated orders, that is also why we focus on top quality products from the first moment. When people realize the good quality price balance, they will come back. When the client finally get a chance to visit us, though they knew us from the old factory, they said this is a good company, with proud, my answer is, we are supported by good customers. It was a nice trip, since we have many projects on going, and also have all the equipment they are interested in stock. Easy for them not only check the photoes, but also the equipment itself, to feel, to touch, to test. Shale shaker for solids control are devices that remove drill cuttings from the drilling fluid while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since solids control is vital in keeping down costs associated with the drilling fluid. The basic design consists of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shakes or vibrates the drill cuttings, commonly shale shaker, across and off of the screens as the drilling fluid flows through them and back into the drilling fluids processing system, often called a mud system. This separates the drill cuttings, often called solids, from the drilling fluid so that it can be recirculated back down the well bore. In oilfield industry,linear motion shale shaker are widely used for drilling mud solids cotrol of oil gas well drilling for rig. As regarding this client, they use our products directly and indirectly, for quite a while they purchased a few mud systems directly from us, then they also tried package from rig companies. No matter which way, they are supprised to find our improvment, better design, more user-friendly, higher efficiency. Since they do have a lot of different shakers, no wonder for big companies, after visited our screen factory, they also very interested in buying more shaker screens, to replace their existing screens. After visited a few other suppliers, our big and well orgnised factory is also impressed all their team. After this visit, their first order is shale shakers, jet mud mixers etc., more under discussion. The latest shale shaker have the composite frame shaker screen, stainless steel shaker screen support frame, ratchet wheel screen reomover etc. Freely to contact us, visit us.

Mining Dewatering System to Vietnam

After grinding mill, need dewater the solids, with strong acid. That was the situation we had, then cooperated with client, we worked together to find a solution. For shale shaker feeding, we choose vertical Netzsch pump, after the shale shaker, the fluids to a small intermediate tank, sucked by a horizontal Netzsch pump, feeding to the GN decanter centrifuge.

To achieve higher capacity, and higher G force, this time we choose a 18in decanter centrifuge, which is GNLW453, with varible speed, the model: GNLW453-VFD, this model is equipped with a variable frequency control panel to realize the different rotary speed. By adjusting the speed, feeding rate, liquid level inner the bowl, the operator could adjust dryness of the discharged solids and clarity of the effluence. The shaker and decanter centrifuge need to be seated on a mud tank so that the liquid discharged could be collected properly. The tank is divided into 2 compartments for collect the effluence respectively from shaker and centrifuge. A mono pump is also fixed on the tank skid for transferring the sludge from tank #1 to centrifuge for further process. For this system, GN have required the materil from Vietnam to the real testing inside factory, before shipment, doing which to make sure the result is as expected. Before getting into this separation system, the operator would have a pit to collect the flushing sludge and then use a pump transfer to the shaker unit. GN’s equipment are widely used in many industries for solids and liquid separation like drilling fluids recycling, dredging slurry separation, crude oil storage tank bottom flushing water recycling etc. Welcome different applications wherever need solid / liquid separation, GN is ready to help.

Shining in OTC 2017, After Tides OFF

Now it is 6th, and after US office opened, always two booth. As leading brand of separation solution brand in China, in the past nearly 10 years since the foundation, GN developed the normal solids control equipment, waste cuttings management system. Keep developing the new equipment, keep doing better and better products and service, makes GN stand out, from numerous manufacturers in the good days. GN new released shale shaker adopts the gear rack technology which makes replacing of the shaker screen much easier than ever before. More interesting is by using the same ratchet wrench, operators can adjust the shaker deck angle during the shaker running so that to make the discharged cuttings much dryer or wetter. Which is now more than a tough machine, also an elegent  one. GN is able to provide replacement screen for almost all popular brand shaker models.
  • Replacement screen for flat type and pyramid type.
  • Replacement screen for hook strip type and frame type.
  • Replacement screen for steel frame type and composite frame type.
  • Should you have any requirement, pls contact GN Solids Control for more information.
High speed centrifuge, and vertical cuttings dryer is also upgraded in details, higher speed, better performance, balancing is one of the critical factors for evaluating the centrifuge performance. GN’s centrifuge is pressed for 3-stage balancing test to ensure the running balance including 1800RPM low speed balancing and real operation high speed balancing as well as the assembly balancing. Except all this, GN is now making a lot of research & development on the new equipment for environmental protection, keep tune to know more.

3 Sets Solids Control Equipment to Europe


GN just finished the fabrication of a batch of solids control equipment for 3 sets oil rig. This order is for a Europe client, and soon later all the equipment would be shipped out. This order includes 3 types main solids control equipment, shale shaker, mud cleaner and decanter centrifuge. GN has upgraded the equipment design few times, below some features on the equipment will make clear why customer choose GN.


For clients far away from China, especially the drill rig manufacture, or packager, normally have the ability to design / manufacture the mud tanks, though it is not just a steel box, comparing other stuff in the whole rig system, it is not so complicate, it is not always economic comparing to high sea freight rate by bulk shipment, and the shipping time is not well scheduled.


Shale Shaker – the shale shaker in this order is used to be the primary shaker in the oil rig mud recycling system. It has 4 panels shaker screenwith each size of 585x1165mm, total screen area 2.7 square meters. At both sides of the shaker, bolted type shaker deck fixing design make it easy for avoiding the shaker deck vibration during transportation. The horizontal beams on both sides of the deck walls make the shaker deck much stronger to bear higher G force. Screen support frame is made of stainless steel for anti corrosion purpose. The embedded hollow rubber seals on screen frame perform a good sealing function and easy for replacement.


Mud Cleaner – GN suggests in the same mud system to use same model shaker as mud cleaner under drying shaker. It would be good for future maintenance and screen ordering from supplier. GN mud cleaner adopts full PU material hydro cyclone for long lifetime, and the cyclone manifold is removable easy transportation. All GN’s shaker has the installation points for quickly fixing the cyclone manifold.


Decanter Centrifuge– both of the bowl and screw is made of stainless steel, the bowl even SS2205 or SS2304, much better than SS316. On protection of the wet touching parts, GN use tungsten carbide tiles for screw and ceramic insert ring for solids discharge port. GN processes 3-stage balancing to maximize the balance of the centrifuge include 1800RPM low speed balancing and real operation high speed balancing as well as the assembly balancing.
