Recently GN solids control shipped one unit of fully hydraulic drive decanter centrifuge to Middle East, this is a new developed decanter centrifuge except for electric drive decanter centrifuge. Till now we have already developed many series decanter centrifuge to be applied for many industry applications.

1)    The hydraulic drive decanter centrifuge is normally used in high temperature ambient for heavy mud with flexible bowl and differential speed, especially in middle east, the environmental temperature is very high.
2)    Compared with the electric drive VFD decanter centrifuge, the fully hydraulic drive decanter centrifuge with compact design, all the driving system, motors, centrifuge bowl assy are installed on the same skid for convenient transportation.

The adjust differential speed allows a better solids separation result for heavy mud.
3)    Except for FHD decanter centrifuge,GN solids control also produce a range of VFD decanter centrifuge, with positive pressurized VFD control panel, ABB brand major electric components inside, PLC smart control, HMI interface, stainless steel cover, self cooling tube or air conditioner for high temperature area.
4)    The centrifuge bowl is made of duplex stainless steel 2205, and the complete screw is made of stainless steel 316, the screw propeller is protected by tungsten carbide tiles, which is repairable, the solids discharge port and fluids distribution port is protected by tungsten alloy insert, the open propeller design increase the treating capacity and made the treating performance better.
The FHD decanter centrifuge has been used for drilling fluids recycling, drilling waste management, waste water treatment, mining tails separation, dredging slurry separation, oil sludge separation, and other solids fluids separation projects.

Recently GN solids control shipped 10 units of centrifugal pumps to Venezuela for oil drilling rig, those centrifugal pumps are C version centrifugal pumps, which is interchangeable with world famous brand centrifugal pump, also the spare parts are all interchangeable.

The applications of centrifugal pumps:
1)    Mixing pump, equipped with mixing hopper, pipelines, control panels combination as jet mud mixer or twin jet mud mixer.
2)    Trip pump for trip tank of solids control system
3)    Super charging pump for mud pump, connected the pipelines with solids control system suction tank
4)    Feeding pump of desander, desilter, mud cleaner
5)    Oil transfer pump, sludge transfer pump

Features of centrifugal pumps:
1)    Wide open vane impeller creates lower axial thrust to improve the working life of bearing
2)    Thick , strong concentric casing provides extended life over conventional volute design, the concentric design minimizes turbulence and abrasive wear.
3)    FAG brand bearing for longer working life and reliable quality
4)    Spare parts interchangeable with the most popular brand centrifugal pump in the world
5)    Pump casing is made of hard ductile iron alloy instead of abrasion resistant
The centrifugal pumps are packed in seaworthy wooden box and loading into standard container shipped by sea. We have shipped a lot of our shale shaker, mud cleaner and shaker screens, decanter centrifuges to Venezuela drilling companies both from China and USA.

ViST is Vacuum Shaker Screen Technology is to work with shale shaker to reduce drilling waste and recycle drilling fluids. This is technology developed by GN solids control, you can see the working video to understand clearly from GN website: http://www.gnsolidscontrol.com/vist-vacuum-screen

The unit is installed under the last screen of the shale shaker or installed externally of the shale shaker. It needs a air compressor to provide air supply for operation, most of the rigs will own one air compressor, no need to buy extrally. The air will create suction on the last screen of the shale shaker, reduce the liquid on the cuttings by 30% to 50%, separation of the fluids out of the cuttings.
It increased the recovery of useful drilling fluids, reduce the drilling cuttings volume, drying the drilling cuttings, so the vertical cuttings dryer working efficiency will be increased, the user will save a lot of the drilling waste treatment cost, and save more cost to prepare for new drilling fluids, so you can be benefit to use ViST vacuum shale shaker screen technology. Compared with the cost to use more drying shale shaker or drilling waste management system, the benefit to use ViST vacuum shaker screen is as below:

1)    Compact design, no need more space to install one more shale shaker or drilling waste management system, the result is to reduce the liquid 30% to 50% of the drilling cuttings for both WBM, OBM or SOBM
2)    Competitive price compared to use more equipments, including screw conveyor to transfer the drilling waste to drilling waste treatment system

This week GN solids control shipped 9 sets of shale shakers to Shandong client, this is their repeat order. We have several models of shale shaker for option:

1)    3 panel shale shaker, GNZS703F with 2.63 m2 total screen area is one of the best sold model among all the models. the 2 vibration motor provide high G force up to 7.5G, the adjustable deck angle adjustment system allow the operator to adjust the deck angle for different purpose during operation, you only need to adjust from one side, then the other side is also adjusted automatically, some other brand shale shaker will need 2 operators to adjust the deck angle at the same time from 2 sides by using same deck angle, it is inconvenient for operation.

2)    4 panel shale shaker, GNZS594F with 2.73 m3 total screen area, the screen dimension is 585x1165mm, the reinforce durable composite material shaker screens are interchangeable with world famous brand shale shaker, the 2 vibration motor provide high G force up to 7.5G, it can separate the solids better so the drilling mud can meet the drilling requirement
3)    2 panel shale shaker GNZS752 with 1.35m2 total screen area, also installed with composite material shaker screens, the working life is 2 times compared with the previous steel frame shaker screens. It is very easy to replace the shaker screens, the operator only need to use the special tools Ratchet wrench to loose the locking wedges, then put the screens on the shaker deck, then use the wrench to lock it again. The whole process did not take 20 seconds, very fast.
