The screw conveyor is used to collect the drilling cuttings from primary solids control shale shaker, then transfer to vertical cuttings dryer; it can be also used to collect the discharged solids from vertical cuttings dryer and transfer to skips. The user can make the auger support at site according to the installation requirement.
If the drilling cuttings have been storage in the waste pit at rig site, the sludge vacuum pump can be used to suck the drilling waste from waste pit and feeding to vertical cuttings dryer, the horizontal transfer distance is up to 500 ~1000 meters, it is specially suitable for transferring drilling waste with high solids content and high viscosity. Except for drilling waste, it has been widely used for oil sludge transfer, industrial waste transfer, sand transfer and industrial waste transfer.

GN Solids to Exhibit at Beijing 2025 CIPPE Oil Equipment Exhibition

GN solids control will attend Beijing 2025 CIPPE Oil Equipment Exhibition. The exhibition information is as below:


Exhibition Name: The 25th China International Petroleum & Petrochemical Technology and Equipment Exhibition
Exhibition date：March 26-28,2025
Exhibition location：Beijing, New China International Exhibition Center
GN Stand number：E2168

What products will be showed at CIPPE exhibition?
1. The 4th generation Fully Hydraulic Drive decanter centrifuge, GN produced fully hydraulic drive decanter centrifuge have been widely used for onshore and offshore drilling fluids treatment. GN FHD decanter centrifuge can be used in high temperature for heavy duty mud with flexible bowl and differential speed. We can design and produce lifting frame and lifting pad which is comply with DNV 2.7/1 certificate to meet the offshore lifting requirement. ATEX explosion proof standard will be applied for class 1 div. 1 application. The hydraulic bowl and scroll drive system drives both the hydraulic motor ROTODIFF and the bowl of a decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits. The bowl material is made of duplex stainless steel SS2304 from centrifugal casting, the screw material is stainless steel 304, and the screw propeller is protected by tungsten carbide tiles for longer working life.


2. The lastest K Version brand new offshore oil and gas drilling fluids shale shaker
3. The lastest G version brand new three phase decanter centrifuge
4. Other solids control equipments: vertical cuttings dryer, big bowl decanter centrifuge, mud cleaner, screw conveyor, solids transfer vacuum pump
5. Drilling fluids shale shaker screens
We look forward to meeting you at CIPPE 2025 and having an in-depth discussion on the future development of the solids control industry. And we are just 1.5 hours drive from the exhibition hall, welcome to visit us after CIPPE.

Double Deck shale shaker and cuttings dryer for Africa drilling company

One set of double deck shale shaker and one set of vertical cuttings dryer are ready for shipment to Africa for drilling cuttings treatment system.
The double deck shale shaker will be applied as high G force drying shaker to separate the coarse solids, it can be used for both water based drilling cuttings and oil based drilling cuttings. The anti splash cover on the top to prevent the drilling mud from splashing. The top layer and bottom layer total 6pcs shaker screens are composite material frame for longer working life and better separation performance.


The vertical cuttings dryer is ideal equipment to be used for oil based drilling cuttings treatment, after treatment, the oil content on the cuttings is below 5%, the fluids will flow to an intermediate tank, then feed the fluids to decanter centrifuge for further treatment, the fine solids will be separated out by decanter centrifuge, the fluids can be reused for drilling. Before treated by decanter centrifuge, the fluids can be treated by drying shaker to reduce solids content, it will increase the decanter centrifuge treating capacity and performance, also it can prevent the centrifuge bowl from damaged by the high solids content.


GN standard drilling waste management system GNCM-40A is consist of VFD decanter centrifuge, vertical cuttings dryer, flushing pump, centrifuge feeding screw pump, fluids collection tank, skid, electric control system, accessories. The compact design with small footprint is loaded into standard container.
Except for drying shaker and vertical cuttings dryer, GN solids control also produce drilling waste treatment decanter centrifuge, including high speed decanter centrifuge, VFD decanter centrifuge, Fully Hydraulic Drive decanter centrifuge, we provide different explosion proof standard for option, IEC EX, ATEX, CNEX. For more information about high G drying shaker and vertical cuttings dryer, pls contact with GN Solids Control.

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：

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.
