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.

Offshore Drilling Mud Centrifuge and Cuttings Dryer to Asia Oilfield Service Company

Recently one batch of offshore drilling mud centrifuge and cuttings dryer are ready for delivery to Asia oilfield service company. The equipments list is as below:


1. 6 units of GNLW363D-FHD Fully Hydraulic Drive decanter centrifuge
2. 2 units of GNCD930G vertical cuttings dryer with skid


3. 8 units of variable speed screw pump, 2 units as flushing pump for vertical cuttings dryer, 6 units as feeding pump of fully hydraulic drive decanter centrifuge
The features of GNLW363D-FHD Fully Hydraulic Drive decanter centrifuge including:


1. ATEX motor and control panel, the cable meets the requirements for use in marine environments.
2. The hydraulic bowl and scroll drive system drived both the hydraulic motor ROTODIFF and the bowl of the decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits.
3. The centrifuge can be used for high temperature ambient up to 55 C degree for heavy mud, suitable for zone 1 and zone 2 application.
4. VISCOTHERM Fully hydraulic drive system
5. Max speed is up to 3600rpm, max G force is up to 2610G.
6. The bowl material is duplex stainless steel SS2304 from centrifugal casting, the screw material is stainless steel 304.
7. The solids discharge port and fluids distribution port is protected by tungsten carbide inserts, the screw is protected by tungsten carbide tiles
8. The bearing is SKF brand
During centrifuge working process, the bowl speed ,differential speed, fluids pool depth, feed rate, flocculant consumption can be adjusted according to actual situation. The higher bowl speed, the drier solids discharge, more clear liquid effluent to be get. The lower differential speed, the longer time of the solids phase stay inside the bowl, so the discharged solids will be drier.
