Not sure how much you know about us, I guess some of you knows we manufactured BEM shaker before, quite advanced, the Elliptical Motion got many advantage: smooth function on drilling cuttings, longer screen panel stay time, anti-blocking screen hole, and drill cuttings not easy to broke etc. Especially suitable for high drilling mud viscosity, small flow rate, larger solids content and breakable drilling mud.


Well as you may hear from many operators, the BEM is idealy a good product, but if you only have this model, then there is a problem, the drilling mud is effecting the shaker balance. GN dual motion shale shaker can be used in different drilling depths and fully treat the drilling mud. Usually, GN linear shale shake is mainly used in the first and second drilling, while the elliptical motion is suitable for the further depth drilling such as ?third time drilling or even in the forth drilling.


That is also why we choose to stop the BEM shaker, there is no point to have one shaker sent to the site which is too fragile. Yet the Dual Motion shaker includes two working mode: one is linear motion and the other is elliptical motion, each mode can be adjusted by using the switch on the control box.

Stay Safe, it will be slow in a period, but it will PASS. Despite the crisis, we sincerely hope all our clients, and whoever happen to notice this article, all it well and stay safe & good health.What you have done to contribute, you stay at home, you keep yourself yourself, you keep your family safe, you keep their life. Lots of us may have to work. Now most of China recovered and started the production. GN have started for quite a while now, recently some shakers and mud cleaners been sent to a local rig site for oil drilling production.

1.GN Drilling Mud DesanderGN drilling mud desander is largely used when eliminate solids larger than 55 microns. Drilling mud desander is shale shake fixed with multiple sets 10 inch cyclones. A centrifugal pump is usually used to feed the slurry into GN mud desander.Cyclone is using centrifugal force to separate mud under a high rotating speed after the centrifugal pump feed the mud at a high tangential speed. Due to the mud is combined with different densities solids and liquid, solids are moving upwards along with the cyclone as the centrifugal force is larger while the liquid is separated with the solids and rotated to fall off to the cyclone nipple. Eventually, solids are separated out from the the top end of the cyclones. And liquid fall on to the shaker screen panel and to be further treated.2.GN Drilling Mud DesilterGN desilter is pretty similar with GN desander. The only difference is GN desilter fixed with 4 inch cyclone groups. It is normally seen that the cyclones are all in even number. GN desilter helps to remove solids larger than 25 microns. When using different API nos. Shaker screens, the bottom shaker can have different cut point.


GN have survived in many crisis now, from the second year we start, the to a few financial crisis, yet we are getting stronger and stronger. If you will need someone to work with regarding the solids control equipment, or environmental protection equipment, GN will be a very good option.

GN Oil Sludge Treating System is a compact designed system, all the treating equipment can be put in standard containers for convenient move.A standard Oil Sludge Treating System is mainly composed by the following treating components:

1.GN Feeding Pump

Due to the oil sludge is usually has a larger density and high viscosity, it’s vital important to use an effective feeding pump to suck the sludge and feed into the afterwards treating unit. Here GN is using vacuum transfer pump, it’s mainly designed to transfer sludge has solids max. 80% and particles less than 75 mm.
2.GN Pre-Mixing and Heating Tank

Heating is usually seen when oil sludge need to add chemicals to dilute. Mud agitators are also used to mix the oil sludge thoroughly. A water boiler will be used to provide hot air to those pipes along the tank.

3.GN Shale Shaker Treating Unit

A submersible pump suck the diluted oil sludge and feed into GN shale shaker treating unit. Double deck shaker is widely seen and anti-sparing cover as well as flushing nozzles are fixed on the shaker to keep the shaker screen from blocking.

4.GN 2 Phase Centrifuge Treating Unit

GN 2 phase decanter centrifuge removes most of the those larger solids from the slurry discharged by shale shaker. After treated by GN 2 phase centrifuge, solids with oil is around 1%-3%. TDU might be used to further treat the solids discharged from shale shaker and decanter centrifuge.

5.GN 3 Phase Disc-Centrifuge Treating Unit

As the key treating equipment, GN 3 phase disc-centrifuge help to get much clear oil (BS & W less than 3%) and clean water (oil is 1000-3000 ppm).

Life goes on.

GN sludge vacuum pump is an ideal equipment to take the slurry from pit due the small footprint, compact structure and moveable design. In the meanwhile, equipped with big power air compressor, the sludge vacuum pump can suck the sludge and discharge the sludge from and to a long distance, which greatly saves the manpower and increases the working efficiency.

GN?sludge vacuum pump?is a 100 percentage pneumatic driving pump that can be used to transfer various materials ranging from liquid, slurry, wet sludge and even solid power and gravels. In many mining site, the miner is using high pressure water to flushing the ore, and then they need to dewater the ore slurry. All the ore slurry will be collected firstly in a pit waiting for transferring to the dewatering machine.

Now GN made centrifuges are classified by 9 inch bowl decanter centrifuge, 14 inch bowl centrifuge, 18 inch bowl centrifuge and 22 inch centrifuge and 30 inch bowl centrifuge. GN made 14 inch bowl centrifuge and 22 inch bowl centrifuge are widely used in solids control, barite recovery etc. Those centrifuges we provided to Russia will be used for solids control of drilling mud for different drilling rigs.?

GN Solids Control decanter centrifuge is mainly composed by rotating bowl, screw propeller, catch box and foundation etc.GN Solids Control has been upgrading centrifuges every other years based on the valuable feedback that collected from the work site. More than 200 sets decanter centrifuges are provided to global customers every year with word of mouth high remarks.
