10 Sets Big Bowl Mud Centrifuge and 5 Vertical Cuttings Dryer for Africa Project

Recently, GN Solids Control completed a large order and is preparing it for shipment to an African client. The shipment includes 10 sets of GNLW453D-VFD big bowl mud decanter centrifuges and telescopic skid, 5 sets of GNCD930G vertical cuttings dryer systems, 10 sets of feeding pumps, 10 sets of screw conveyors, and other equipments. All of these units have been tested, inspected, and packed, ready for delivery.

The GNLW453D-VFD is a high capacity decanter centrifuge designed for drilling mud and waste management. Its big bowl design improves separation efficiency and processing capacity, while the VFD control system allows operators to adjust bowl speed and differential speed according to actual mud conditions. This helps recover more valuable drilling fluid, reduce waste volume, and improve overall solids control performance. The matching skid ensured stable operation and convenient installation on site.

The GNCD930G vertical cuttings dryer is widely used for treating oil based and synthetic based drilling cuttings. It recovers valuable drilling fluid from cuttings and reduces the oil content in discharged solids, helping clients meet environmental requirements and lower disposal costs. The 5 vertical cuttings dryer systems will work together with the decanter centrifuges to form an efficient drilling waste management process.

In addition, the 10ea feeding pumps and 10ea screw conveyors are included to ensure smooth material transfer throughout the system. The pumps feed drilling mud to the centrifuges, while the screw conveyors transport solids between different processing units. This complete package provides a reliable and integrated solution for drilling waste treatment.

Before shipment, each unit was carefully inspected and tested to ensure quality and performance. The equipment is now being prepared for long-distance transportation to Africa. Once installed, the system will help the client improve drilling fluid recovery, reduce waste, and enhance operational efficiency.

We look forward to supporting the successful operation of this project in Africa.

Hydraulic Drive Mud Centrifuge and Cuttings Dryer for Asia Client

One unit of hydraulic drive mud centrifuge and vertical cuttings dryer are ready for shipment to Asia client.
Fully Hydraulic Decanter Centrifuge (GNLW363D-FHD)


GNLW363D-FHD centrifuge is fully hydraulic drive. The bowl speed and conveyor speed is adjustable within the permitted range. It can achieve independent, stepless and large range speed regulation for the bowl and conveying. The bowl speed and conveyor speed during working is showing on the screen.
GNLW363D-FHD centrifuge is mainly composed of rotating assembly, hydraulic drive system and inlet and outlet interface device
Unlike conventional electric driven VFD decanter centrifuge, this fully hydraulic drive decanter centrifuge features a cutting edge hydraulic drive system. The system drives both the conveyor and bowl from a hydraulic pump unit through two independent hydraulic oil circuits, enabling precise, independent, and infinitely variable adjustment of bowl speed and scroll differential speed—even during operation
Vertical Cuttings Dryer (GNCD930G)


GNCD930G vertical cuttings dryer, it is a core piece of equipment for drilling waste management. Primarily designed to treat drill cuttings discharged from shale shakers when drilling with oil based or synthetic based mud, the cuttings dryer utilizes high speed centrifugal force to effectively remove residual liquid from cuttings. The GNCD930G is engineered to achieve an Oil on Cuttings (OOC) level as low as 3%–5%, meeting stringent environmental standards while allowing valuable oil-based mud to be reclaimed and returned to the drilling system
This significant shipment to an Asian oilfield service company underscores GN Solids Control’s commitment to providing high-quality, reliable equipment for offshore drilling operations worldwide.
s a leading manufacturer with API certification, GN Solids Control continues to support the global oil and gas industry’s efforts toward more environmentally responsible operations by delivering advanced, high-performance solutions.

Solids Control equipments ready for delivery

One batch of solids control equipments are ready for delivery for our international client, this is the third time repeat order from the same client. The solids control equipments purchased is for their solids control service contract. The equipments list including:
1. Decanter centrifuge, GN solids control can produce both fixed speed decanter centrifuge and VFD decanter centrifuge, the most popular model is 14 inch bowl decanter centrifuge. It can be used for both solids control drilling fluids treatment and drilling waste treatment system.


2. Vertical cutting dryer, it can be used for oil based drilling cuttings treatment, after treatment, the oil on the cuttings could be reach below 5%.
3. Screw pump, we have fixed speed screw pump and variable speed screw pump, it can be used as decanter centrifuge feeding pump and vertical cuttings dryer flushing pump.


4. Screw conveyor, we have fixed speed screw conveyor and variable speed screw conveyor, it can be used to collect the drilling cuttings from solids control shale shaker, and transfer to vertical cuttings dryer feeding port.
5. Vacuum pump, it can be used to transfer drilling waste cuttings, also it can be used to collect spilled drilling waste from the rig platform.
6. High G drying shaker, it can be used to treat water based drilling cuttings, and it can be used to reduce the solids content from the drilling waste, so the treating capacity of the decanter centrifuge can be improved.
All equipment has undergone factory acceptance testing (FAT) and is packed in export-grade, weatherproof packaging to ensure safe ocean freight transit. Delivery is scheduled for next week, with a company technician available for remote or on-site commissioning assistance as part of the service contract agreement.
If you need good quality good performance solids control equipments, pls contact with GN solids control.

GN Solids Control Equipment and Vacuum Pumps for MENA client

One batch of vertical cuttings dryer, decanter centrifuge and vacuum pumps are ready for delivery for NEMA client.


The MENA region, encompassing key energy players such as Saudi Arabia, UAE, Kuwait, Egypt, and Algeria, requires equipment that can withstand extreme ambient temperatures and abrasive desert conditions. GN has confirmed that this specific batch has undergone rigorous factory acceptance testing (FAT) with an emphasis on:
Corrosion resistance for high-salinity formations.
High-temperature tolerance for hydraulic and lubrication systems.
The integrated system is designed to provide a closed-loop, zero-discharge solution for drilling fluid recovery and cuttings treatment. Here is a breakdown of the key components being delivered:
1. GN vertical cuttings dryer
Utilizing high-G force, this unit is engineered to recover valuable base oil or synthetic drilling fluids from OBM cuttings. By reducing the oil on cuttings content to less than 5% (by weight), the dryer not only saves significant fluid costs but also minimizes the environmental footprint of drilling operations—a critical factor for operators working in the sensitive desert and offshore environments of North Africa and the Middle East.


2. High speed decanter centrifuge
GN solids control is an OEM manufacturer of drilling fluids and drilling waste decanter centrifuge, we can produce high speed decanter centrifuge, middle speed decanter centrifuge, VFD decanter centrifuge, FHD decanter centrifuge. We can produce different bowl size decanter centrifuge, 9 inch, 14 inch, 18 inch, 22 inch, 30 inch. The discharged fluids from vertical cuttings dryer will be storage in catching tank, then the decanter centrifuge feed pump suck the fluids to decanter centrifuge for further treatment.


3. Vacuum pump
It is a 100% air operated vacuum pump for liquid ,slurry, and solids transfer. The pump can transfer material with high gravity and high density, with dry solids material or slurry with solids content max. up to 80%.
