As a professional FHD decanter centrifuge manufacturer in China, GN solids control produce both FHD decanter centrifuge and VFD decanter centrifuge. Fully hydraulic drive decanter centrifuge is new developed centrifuge compared with our mutual series VFD decanter centrifuge. Features of GN brand FHD decanter centrifuge as below:

1) Compact design, all the hydraulic drive system imported from Europe, the main motor ( explosion proof, IEC or ATEX), electric control panel, centrifuge bowl assembly, bearing , skid are installed on one skid for convenient operation, convenient transportation, and save space for installation.
2) Big bowl speed adjustment arrange, Big differential speed adjustment range for better separation result, it can treat the drilling fluids drier and recycle more clean fluids, and separate more solids.
3) It is more suitable for heavy duty drilling fluids and specially in high temperature area, like India, Middle east, Brazil, Africa etc. area.

GN VFD decanter centrifuge is also very suitable for extremely high and extremely low temperature area, like Russia, and above mentioned countries. When the environmental temperature is below 40 degree, the VFD self cooling tube installed inside the VFD control panel is enough. When the temperature is lower than 55 degree, we need to use an air conditioner for cooling, so that the VFD control panel can be operated 24 hours per day continuously without over heating to break. If use normal explosion proof VFD control panel, it will break very easy in hot weather.
The positive pressurized VFD control panel with stainless steel material cover, equipped with ABB brand inverter for main motor, back drive motor, pump motor, PLC smart control, HMI interface, the operator only need to connect the cable gland with the VFD control panel.
If you need FHD decanter centrifuge and VFD decanter centrifuge, pls contact with GN solids control.

A lot of clients are asking for ViST Vacuum Shale Shaker Screen Technology to GN solids control, now the technology is already available to sell, pls contact with GN sales engineer to get more information, and understand more from the video : http://www.gnsolidscontrol.com/vist-vacuum-screen

The basic technical specification is as below:
Item Specs
Supply Air Pressure 0.7-1.0Mpa (100-150PSI)
Air capacity required 4.5 m³/min (160 CFM)
Operation Shaker For 2 -3 Shakers
Applicable Mud OBM,SBM,WBM
Recovery efficiency 30%-50%
Mud Temperature -15 +85°C
Control System Air operated Automatic control
Time for Suction Adjustable per drilling conditions
Dimension (Weight) 840x640x1050mm ( 400KG )
Electrical Power No required, only need Air supply

Based on different site schedule, the installation of Vist vacuum shaker screen unit have 2 ways: 1) it is installed externally of the shale shaker, there is one pipe to connect to the last shaker screen of the shale shaker; 2) it is installed under the last shaker screen of the shale shaker when there is enough room.

The purpose to install the vacuum is to reduce drilling waste:
1) Reduce the volume of drilling waste, the drilling cuttings will be much drier, the fluids on the cuttings is reduced 30% to 50%, so the further drilling waste treatment cost is much cheaper, or the transportation cost of drilling cuttings is cheaper
2) Increase the drilling fluids recovery efficiency, save the cost to prepare new drilling fluids
3) Save the cost of the client to buy more equipments, such as drying shaker, shaker screens, vertical cuttings dryer, etc, also save the space to install these equipments

Recently GN solids control shipped 8 sets of shale shaker without vibration motor shipped to our clients, the client will install the vibration motors by themselves who had installation capability. This is not the first order from this client, they repeat orders because they are satisfied with the working performance of GN shale shakers which they ordered before.

Shaker deck is the most esscential components for a shale shaker, the bottom material treatment before painting, we owns our ball blasting machine, the ball blasting degree is 2.5 with working life 10 years more, we can control the bottom treatment quality better, unlike other solids control manufacturer in China, they use sand blasting which is provided by third party supplier. 3 layers painting and coating by choosing Japan Kansai or US ppg brand painting, to promise the shaker deck not to get rusty and abrasion during the operation. In some tenders, it required the complete the shaker deck( all the vibration and non vibration components) are made of stainless steel material, it will increase the shaker production cost a lot and the the client has to pay more money.

The deck bottom of GN shaker is made of stainless steel material, and the unique rubber sealing technology to ensure the reliable performance of the rubber sealings, we also use GN own made composite material shaker screens, the working life is 2 times compared with the traditional steel frame shaker screens.
