GN got large orders on solids control system

Each year, GN Solids Control has supplied turn-key solids control systems to worldwide clients. Many clients are pleased with the great quality and after sales service, so many of them came to GN and put a repeated order.

Lately, GN Solids Control got one large order from Europe. This client bought three sets solids control systems for the 1000 Hp drilling rig. They're pretty pleased with GN Solids Control System because they've been using GN 750HP drilling rig mud system for quite a long time. So that they came to GN and put these 3 sets order.

These 3 sets mud control system has finished and therefore are being examined within our Chinese factory at this time. They're mainly includes the bellowing tools:

1. Shaker Tank

You will find 3 sets GN shale shaker tanks. Six sets GN shakers happen to be installed on them, in addition to three sets GN mud cleansers and three sets GN vacuum degasser.

2. Centrifugal Tank

Here the centrifugal tank is outfitted with two sets GN decanter centrifuges. The first is middle speed decanter centrifuge, which is often used to split up probably the most solids. And also the second decanter centrifuge is really a high-speed decanter centrifuge, which is often used to split up the finer solids in small diameters.

3. Active Tank

This tank is mounted with a few sets GN mud agitators and GN mud guns.

4. Suction Tank

It’s also outfitted with mud agitators and mud guns.

5. Mixing Tank

It’s outfitted with GN mixing hoppers and GN mixing pumps. All of the solids could be included this tank, and delivered to the drilling rig for reuse.

Now GN Solids Control can offer turn-key solutions for drilling liquids control, and every one of the GN devices process the certification of explosion-proof for example ATEX or IECEX. GN Solids Control is among the couple of companies in China that may provide CE licensed items.

Decanter centrifuge with VFD control panel

You will find fixed speed control and variable frequency control for oilfield decanter centrifuge. For fix speed user interface, the centrifuge speed is dependent around the lever and belt. The rate is bound and can't be change.

For VFD user interface for decanter centrifuge, the centrifuge max. running speed with respect to the lever and belt. With the charge of VFD panel, centrifuge speed could be modified from 0 towards the max. speed, to in the set min. towards the set. max. speed.

You will find normally 3 VFD control for decanter centrifuge with the VFD panel.

1) The first VFD is VFD control for primary motor. Decanter centrifuge speed could be transformed via alter the frequency of primary drive motor. Most centrifuge providers, they'll choose VFD control for that primary motor drive.

2) The 2nd VFD is VFD control for back drive motor. The part of back drive motor is cooperating to alter the centrifuge differential speed. Differential speed may be the primary step to affect separation result.

Formula: Differential speed = Bowl input speed - conveyor input speed / the differential ratio.

The differential ratio speed is really a fixed speed, when both Bowl input speed and conveyor input speed changeable, customer is much more flexible to obtain more reasonable differential speed.

3) The 3rd VFD is VFD control for centrifuge feeding pump. Many centrifuge providers, they don't choose this VFD control. GN Solids Control company VFD centrifuge with VFD control for feeding pump and thru PLC system to understand automatic wise charge of the centrifuge.

GN Solids Control is China leading manufacturer on oilfield decanter centrifuge. Each year, they offer 200~300 sets different model centrifuges to worldwide nations, like U.S.A, Canada, Belgium, Cyprus, Australia, India, Indonesia, Malaysia, Singapore, Thailand, Russia, Kazakhstan, South america, Algeria, Nigeria, Egypt, Iran, Iraq, UAE, Yemen, etc…

Besides oilfield decanter centrifuges, GN Solids Control offers linear motion shale shaker, mud cleaner for solids control and vertical cuttings dryer for drilling waste management. For additional inquires, greet you visit GN website or send mail to for inquire.

Solids Control Decanter Centrifuge for Africa Drilling Rig Program

GN decanter centrifuge is a vital component in drilling liquids cleaning system on the drilling rig. To keep drilling fluid within an optimum condition leads to less wastage, a higher efficiency from the solids control system and reduced operating cost. Particularly in Africa oil & gas drilling market, GN decanter centrifuges are identified by the drilling company, Oil & Gas Company and contractor.


1. For separating fine contaminants or solids, mechanical separation of solids from drilling liquids by using a decanter centrifuge is really a highly-effective way of maintaining proper drilling mud density and viscosity. GN decanter centrifuges have abilities to keep the mud condition inside the recommended range based on drilling program. Generally, decanter centrifuges would be the last processing within the closed loop solids control system.

In weighted drilling mud, decanter centrifuge recover a lot of heavy barite, which is used again within the drilling liquids system. Within the general application, centrifuges are utilized for getting rid of the fine solids and contaminants.

In dewatering systems, decanter centrifuge considerably reclaim the liquids and enhance solids control system efficiency


Decanter centrifuge model: GNLW363CG

1.14” bowl diameter with 50” length for 130gpm capacity

2. Explosion proof standard motor and user interface assure the safe working atmosphere.

3. Ceramic protection and different design feeding method assure GN decanter centrifuge sturdiness

4. Simple adjustable liquid pond control water content of solids.

5. Variable speed drive can also be obtainable in GN decanter centrifuge to regulate the rate from Revolutions per minute to 3200 Revolutions per minute to be able to satisfy different mud condition.

According to your process needs, we wish to optimize your decanter selection including large capacity of centrifuge GNLW553 with 400GPM, high rotary speed of decanter centrifuge GNLW223 with 3800RPM and occasional gravity GNLS452 for barite recovery application. GN decanter centrifuge is dependent on your actual requirement.
