GN Shaker Screen is a subcompany of GN solids control which is API Q1 certified company.
GN 9inch Centrifuge Used For Aluminum Oxide Slurry
GN Solids Control manufactures different sizes of decanter centrifuges. GN 9inch bowl centrifuges are largely used in small volume slurry treating, such as the chemical slurry, pharmacy slurry, diamond drilling slurry etc. 
There are hundreds sets of GN 9 inch centrifuges working in USA and Canada. Several weeks ago, GN Solids Control provide 6 sets to a USA customer. This customer will use GN centrifuge to treat Aluminum Oxide Slurry.
The Aluminum Oxide slurry solids content is around 8% to 10%, customer would like to thickening the slurry into 60% to 80%. By using a chemical mixing tank with a GN mud agitator, the solids Aluminum Oxide Slurry is mixed with water first. Then it is feed into GN 9 inch bowl centrifuge by using GN screw pump.
In order to eliminate those finer solids, GN chemical dosing unit is also used. Sometime, customers might not want to use chemical dosing unit due to environment protection rules, because using chemicals might cause pollution. One GN Slant Plate Clarifier might be used after the slurry treated by GN decanter centrifuge.
GN 9 inch centrifuge has 2 models: variable speed and fix speed. GN 9 inch centrifuge is mainly including the following components: rotating bowl, screw conveyor, centrifuge frame and driven motors. Some customer also purchase GN centrifuge rotating assembly (rotating bowl and screw propeller) to modify by themselves. GN 9inch centrifuge now has 2 version, the D version is fixed by only one driven motor while the E version is fixed with 2 driven motors. 
GN Solids America LLC is located in Houston, TX. GN has several 9 inch centrifuges in stock as well the other models such as 14inch centrifuge. GN Solids Control centrifuge has a wide usage for different slurry separation. Please feel free to connect with GN sales for your decanter centrifuge usage.
GN Solids Transfer Pumps
GN Solids Control manufactures different models transfer pumps or conveying equipment. As long as the materials can be moved, they can be transferred by GN pumps.
There are many pumps distributors are selling pumps that made by GN Solids Control. Today we would like to share several pumps we provided to our customers.
1.GN Centrifugal Pump
GN made centrifugal pumps are replaceable with NOV Mission Magnum pumps. GN centrifugal pumps are widely used in move different slurry. In the solids control and waste management treating area, GN centrifugal pumps are largely used to feed drilling mud into GN desanders and GN desiltes as well as GN Mud Cleaners.
Centrifugal pumps are wearable pumps, they wear fast when the slurry has too much solids inside. Pump shell and impeller must take extra protection process in order to run for a long time. 
2.GN Screw Pump
GN Screw pump is also called GN positive displacement pump. This pump has a very large push force for high density drilling mud. It’s mainly used as a feeding pump of the decanter centrifuge.
Screw pump can not be used when there are too much solids (over 30%), it will get blocked easily. So a GN shale shaker must be used if there are too much solids. 
3.GN Submersible Pump
GN Submersible pump is mainly used to transfer slurry with high content solids and larger particles. It can be also used as a feeding pump for GN decanter centrifuge.
4.GN Vacuum Pump
GN Vacuum Pump is a newly developed equipment to transfer all materials to a long distance (max. 1000m). Different with the above mentioned pumps, GN vacuum pump is driven by air force. If those above pumps need to consider the explosion-proof standards, then you don’t need to worry about GN vacuum pump. But you will need to use an air compressor to provide enough air to driven the vacuum pump for sure.
GN Solids Control Ship Equipment to Russia
GN Solids Control has provided thousands of solids control and waste management equipment to global customers this year. Last month, GN Solids Control shipped a large quantity of solids control equipment to one Russia customer.
Here are the main solids control equipment we provided:
1. 8 Sets Shale Shakers
GN Shale Shaker is the first treating unit when drilling mud comes from the drilling rig. By using different API nos. shaker screens, GN shale shaker help to remove most of the solids larger than 100 microns. 
2. 6 sets Mud Cleaners
GN mud cleaner is GN shale shaker fixed with 4inch cyclones and 10 inch cyclones. Usually 10inch cyclones remove solids larger than 55microns while the 4 inch cyclones help to eliminate solids larger than 25 microns.
3. 3 sets Centrifugal Degassers
GN centrifugal degassers are especially designed to use in narrow working room if the mud tank is too small. It plays the same function as the vacuum degasser.
4. 4 sets Decanter Centrifuges
GN decanter centrifuges are the most cost effective treating equipment which are largely used in solids and liquid separation, not only in the oil and gas solids control and waste management treating area, but also widely used in the other slurry treating, like hydrovac slurry treating, mining slurry treating etc.
GN decanter centrifuges are using tungsten carbide tiles to protect the screw propeller for long time usage. GN centrifuge rotating bowl is made by centrifugal casting. Now GN has 9inch, 14inch, 18inch, 22inch and 30 inch bowl centrifuge for choose. 
5. 10 sets Centrifugal Pumps
Centrifugal pumps are largely used to transfer solids. GN made centrifugal pump is interchangeable with NOV Mission Mangum pumps.
6. 2000 pcs Shaker screens
Beside those above treating equipment, customer also purchased 2000 pcs shaker screens from GN. All screens are composite frame ones, which are much better than traditional metal frames ones. GN Houston warehouse also has thousands screens in stock.
