GN Solids Control has been manufacturing shaker screens for many years. Now GN Houston branch company which is GN Solids America LLC has thousands of shake screens in stock.
GN Shaker screens are widely used in hundreds of drilling rig sites. As we all know, shaker screens are wearable parts, they all need to be changed after used for some days in order to have a clear drilling mud. GN made shaker screens can be used on most those largely used shakers, such as NOV shaker, Mi-Swaco shaker and Derrick Shaker etc. Before GN Solids Control manufactured hundreds of metal frame shaker screens, but with the new technology usage, more and more customers prefer to use composite frame shaker screens. GN made composite frame shaker screens are tested to last longer than traditional metal frames, which are also provided during parallel testing.
GN Solids Control is always devoted to provide the most cost-effective shaker screens to global customers. Even in US, many customers keep using GN shaker screens.
So why GN made composite frame shaker screens are better than those metal frame ones?
1.GN composite frames screens are using new technology. Inside they are still metal frames which are welded by automatic robot welding, and the screen frame are sent to Inject Moulding machine to cover a layer of high quality plastic.
2.By using the same screen cloth manufacturer with Derrick and Mi-Swaco, GN Solids Control keeps the screen quality at high standard.
3.Most shaker screens manufacturers are using 3 layers screen cloth when API no. Larger than API 120, while GN Solids Control use 3 layers start from API 60. From this point, GN shaker screens can also long longer.
4.GN Solids Control is the first the only one that can pass the third party test report.

GN Soids Control has designed and manufactured many sets of hydrovac slurry treating systems to North America.
Here are some other questions that asked by our customers. In our system, we fixed 2.5inch opening gratings to catch rocks. Do you want to add a second grating with smaller openning？ 
Shaker Tank System GNXT7015-02 
What is back up plan if we experience surge runoff and/or rapid frequent plugging of coarse shaker ZKR-1230 wedge wire screen panels?
One of your workers should monitor the coarse shaker when hydrovac truck dumps into the catch hopper. So if he noticed surge run off of rapid plugging, will need to decrease the feeding, use high pressure water to flush the screen panel to clean thoroughly. In fact, all the screen panels must be cleaned thoroughly every other time in case they are blocked, especially the finer shaker and desilter shaker's screen panels. 
We know of other operations mostly converting to polyurethane of coarser 3 or 4 mm opening. Do you have these? Would coarsening plug pump?
2mm is advised by our customer, we do manufacture coarser opening screens. 
If changed to coarser opening, the submersible pump wears fast (such as the impeller), bearing also has a higher chance to broke when the duty increased. There is not specific data we can give due the slurry varies a lot. The good point is coarse shaker treating flow rate will be increased, while the discharged solids will be a little bit more moisture.   
In addition to coarser polyurethane screen openings, spray nozzles are mounted above screen often needing supplemental hosing beyond that.
BTW, GN Solids Control just provided another 4 sets hydrovac slurry treating systems to USA customers. In order to have a larger treating flow rate, we provided a decanter centrifuge from 22inch to a 30inch centrifuge.

GN Solids Control provided some sets of hydrovac slurry treating systems in North America. By using one set of GN hydrovac slurry treating system, it can help to treat 30~50 truckloads every day.
Today we would like to share some questions our customers have, hopefully if you have similar questions, you will also find answers in the following:
1.What do you think about us pumping clean mud through these nozzles? We are very concerned about preserving water! Can we possibly re-direct mud from GN submersible slurry pump GN50YZ40A-10 on coarse shaker tank to introduce into flush nozzles?
Suggest you pump the water discharged from GN decanter centrifuge to flush, or at least use the water from the desilter tank. Too many solids in the coarse shaker tank, might block the nozzles. 
2.What is your experience with functionality of guillotine valve critical to control feed to coarse shaker? We add motor actuation to this valve.
According to our former experiences, our customers usually keep the valve in a normally open status, which is seldom adjusted. Slurry discharge is controlled by the hydrovac truck. It's good to use a motor actuation for sure, as long as the coarse shaker can treat all the feed slurry, you can leave the valve fully open.  But use motor actuation is option for high configuration system.
3.What do you think about install of removal grizzly bar sets at grade above square mesh for safety/ease of picking out rocks, trash,etc..? 
In our hydrovac slurry treating system, we fixed 2.5inch opening gratings to catch rocks. Do you want to add a second grating with smaller opening？GN opening gratings also help to protect the coarse shaker.
Now all those GN hydrovac slurry treating systems running well in customers’ work site. If you are feeling headache for treating hydrovac slurry, come to GN Solids America for your customized solution.

GN Solids Control has been manufacturing decanter centrifuges for many years. GN 9 inch centrifuge as one of the smallest rotating bowls centrifuge, it is widely used in diamond drilling, mining slurry treating area and lab scale slurry treating etc.
Before GN Solids Control only provides one model 9 inch centrifuge that are mainly suit for small volume treating such as diamond slurry treating. Now GN Solids Control is happy to announce that GN 9 inch centrifuge also has 3 different models:
1.GN P Series
GN P series decanter centrifuge is also called GN dewatering centrifuge. The beach angel is designed at 11 degree. It’s mainly designed to use in the following area: drilling mud, oily sludge, sand washing etc.
2.GN Y Series
GN Y series decanter centrifuge is called GN Separation centrifuge. Beach angle is 15 degree. GN Y centrifuge can be perform well in chemical slurry, fruit juice, milk treat.
3.GN C Series
GN C series decanter centrifuge is called GN Clarifying centrifuge. Beach angle is 20 degree. It is suitable for protein, beverage, edible oil etc.
All the above centrifuges are driven by 2 main motors, better than the former version with only one driven motor. Centrifuge rotating bowl length also increased in order to have a higher treating demand.
GN 9 inch centrifuge also has 2 control mode: one is fix speed control and the other is VFD control. Not the sames as those big bowl centrifuge, now GN Solids Control mainly provided 9 inch centrifuge with the VFD control box without HMI, which is optional.
In order to protect the centrifuge well, GN Solids Control also provides temperate sensors and vibration switch to monitor the 2 main bearings’ temperature and abnormal vibration of the rotating bowl assembly.
