GN Solids Control is top 3 separation equipment manufacture certified by API in china since 2007. Our shale shaker screen. Over 10 years manufacturing experiences in shale shaker screen industry, now we not only produce for our own shale shaker, but also for international famous MI-SWACO shaker, Derrick shaker, Nov brandt etc. Furthermore, we also can manufacture according to customized requirement.

Our advantage for shale shaker screen:
1. Automatic Robot welding of the steel frame, which will reduce labor cost and the quality will be more stable and consistent.
2. High quality fiber glass, which will improve the screen quality and can bear high temperature to 140 c degree.
3. Four sides’ tension of mesh during heat press, which will minimize the gap between the top screen and support screen for long time use. Our competitors normally don’t use this kind of technology.
4. GN 3 layer wire mesh for API 60 and above, our competitors only can use 3 layer for API 120 and above, that is our strength.
5. GN high level wire mesh configuration is compliant to API RP 13C, which can be used for longer.
6. GN can produce not only for our own brand shale shaker, but also for many international famous brands, such as MI-SWACO, DERRICK, NOV BRANDT etc. Our shale shaker screen can be well compatible with those brands shale shaker.
7. Composite frame screen whose screen can be replaced, clean and reused, this will reduce cost, also increase its life. Besides increasing useable area 10% to 20%.
8. The composite frame is covered by plastic, it is easy to clean and can be stored for more than 5 years.
9. Flat and pyramid screens are available, this will give our customers more choice.

Shale shaker screen working mode:
Shale shaker screen is installed in the shale shaker; it can be used to filter drilling sludge and other industrial sludge. When sludge pass the screen, the particle smaller than the screen hole and fluid will cross over the screen and come into recycling, those particle bigger than the screen hole will be transported out. That is the working mode of shale shaker screen. Furthermore, customer can install two pieces of screens in one shale shaker, one screen is up and another is down, the up screen should be big mesh, and the down screen should be small mesh, but their gap shouldn’t be too big, such as up screen is 100 mesh, down screen is 80 mesh, this situation is ok, if up screen is 100 mesh, but down screen is 50 mesh, this will be wrong operation.

Now we have been exporting more than 70 countries, you can see our shale shaker screen everywhere. If you are interested in our screens, please don’t hesitate to contact us. We are available here to support you.

Mud agitator installation and maintenance
1, the slurry blender when installation should be lifting mixer and placed in the position of the desire to install smoothly, adjust the coaxial degree < 0.39 mm will be 4 M16 hole only after welding on the tanks, fixed and tighten mounting bolts.
Rigid coupling must be equipped with 2, mud agitator trampoline and should be solid and reliable, otherwise it will cause a wave wheel shaft deflection, intensifying gear wear and tear.
3, mud agitator operation should be the same in the ring, cassettes, the high temperature anomalies.Otherwise should stop check, troubleshooting.
4, mud mixer reducer oil level height should be kept in the central visual oil window position, the work can often make up of lubricating oil.It is recommended to use 120 # industrial gear oil.When the site can not meet, also can use other size appropriate lubricating oil

YLS machine is continuously lubrication system. With Timer, it can also used for intermittent lubrication. The lubrication viscosity between 30 ~250 cSt, new lubricating oil is required
Spit pressure can be max. 15kgf/cm². To protect the system peripheral, relief valve is equipped to keep the stability of lubrication system. When the oil level goes down the min, the lubrication system will give Alarm signal, or stop the dryer via external controller.
adding oil: Open the cover and add the clean lubricating oil, to 80% in oil level, then cover it. Only GN appointed lubricating oil or equivalent oil can be used
oil pipe connection: Take the casing pie cap and casing pipe out, put it on the oil pipe. Then, insert the oil pipe into the connection to avoid oil leakage.tumblr_m5a7omfwgO1qmyjkk
installation of power and alarm: Loose the screw and take out the cover of wire, there is pressure signal and level signal underside. There is a fixed head to fix the cable nearby. Rotate out the fixed head and get the cable through. Push it into wire cover and then fix the cable.
Connect the pressure signal and level signal. When the level close to Min. level, the level signal will give alarm; when the oil pressure reach to 2.1 kgf/cm², the pressure signal breakover.After finish the connection, cover the cable, fix the fixed head. If all the connection iscorrect, the lubrication system will work.
Note: the pressure switch and level switch is not ex-proof. Customer can do some actions to make it ex-proof.
pressure adjustment: Loose the screw of adjustment valve, (EX-works 15kgf/cm²), switch on the power. When the oil flow out 5~10s, then tighten the adjustment valve
