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.

Drilling Fluids Solids Control Centrifuge Unit for overseas drilling company

One batch of drilling fluids solids control centrifuge unit are ready for delivery for overseas drilling company, including the equipments list below:
1. Two sets of diesel driven hydraulic decanter centrifuge GNLW223D-FHD

for diamond core drilling waste water treatment project. GNLW223D-FHD hydraulic centrifuge system for the solid-liquid separation of coring drilling mud. It can operate without an electrical power supply, using a diesel engine to supply power, and a hydraulic driven centrifuge and feeding pump to carry out drilling mud treatment, prepare drilling mud, recover drilling fluid, reduce drilling waste, and meet environmental protection requirements.
2. One set of GNLW363D-VFD variable speed decanter centrifuge for oil drilling solids control system, it is a high-performance variable-frequency-drive decanter centrifuge. The VFD technology allows operators to adjust the bowl speed and differential speed in real time, optimizing separation efficiency according to changing drilling fluid properties and solids load.


Key features:
• High rotational speed and G-force for fine solids removal (down to 2–5 microns).
• Energy-efficient VFD control reduces power consumption and extends component life.
• Seamlessly integrates into standard oil drilling solids control systems as a second- or third-stage cleaning device.
• Enhances barite recovery and lowers overall mud costs.
3. One set of shale shaker GNZS593K and one set of GNLW363D high speed decanter centrifuge for HDD trenchless mud recycling system.


GNZS593K shale shaker features a large screening area (three panels) and high G-force exciter design. It removes coarse drill cuttings and large solids as the primary separation stage, ensuring that only fine particles are passed to the centrifuge.
GNLW363D decanter centrifuge – Acting as the secondary or polishing stage, this high speed decanter centrifuge removes ultra fine solids (down to 2–5 microns), allowing the recycled mud to maintain proper rheology and density for extended re-use.

Two Package Drilling rig Solids Control Equipment for Middle East Client

Recently two package of drilling rig solids control equipments are shipping to Middle east client. The equipments list including:


1. 6 sets of drilling fluids shale shaker
As the first phase of solids control, these high-performance shakers are engineered to remove large cuttings and debris from the drilling fluid. With high G-force output and large screen areas, these six units ensure that the client can maintain high circulation rates while efficiently separating solids, protecting downstream equipment from abrasive wear.
2. 2 sets of drilling fluids mud cleaner
Positioned downstream from the shakers, these mud cleaners combine desanders and desilters in a compact unit. They are critical for removing fine sand and silt particles (15-74 microns). By integrating hydrocyclones with a fine-mesh shaker screen, these two units will allow the client to significantly reduce dilution rates and lower overall mud costs.


3. 4 sets of drilling fluids decanter centrifuge
For fine and ultra-fine solids separation, the four decanter centrifuges represent the pinnacle of the system. Operating at variable speeds, these centrifuges will recover barite, remove colloidal solids, and ensure that the drilling fluid maintains the precise density and viscosity required for challenging Middle Eastern formations. GN decanter centrifuge has been widely used for drilling mud cleaning, drilling cuttings treatment, oil sludge cleaning and other industrial waste water solids liquid separation.
Shale shaker, mud cleaner and decanter centrifuge is the major solids control equipments for drilling rig solids control system. Except for these equipments, we also produce vacuum degasser, shaker screens, centrifugal degasser, desander, desilter, mud agitator, mud gun, mixing hopper, vertical cuttings dryer, drilling waste decanter centrifuge, high G drying shaker, mud tanks and complete set of oil sludge treatment system, drilling waste management system, dewatering unit.
