GN high speed decanter centrifuge is widely used in oil & gas drilling, CBM, HDD, drilling waste management, waste water treatment, oily sludge separation, clay mine, tank cleaning, as well as mining industry.
Last week, GN decanter centrifuge system was dispatch for a East Asia customer. The system will be used for mining industry. The function of the system is to reduce the water content.
The decanter centrifuge system including following:
1) 1 ea shale shaker GNZS594E.
It is 4-panel shale shaker with linear motion. The shaker screen we have steel frame and composite material for option. The shale shaker can be used to treat drill mud as solids control shale shaker. It can also be used as High G drying shaker with high G force to treat drilling cuttings. The linear motion design with Adjustable high G force make GNZS594 very popular for any types of drilling including: oil gas drilling, CBM drilling, HDD, water well, geothermal well drilling mud cleaning. The simple but heavy duty design makes GNZS594 shale shaker have reliable operation with less maintenance.
2) 2 ea decanter centrifuge GNLW363CG-VFD.
It is GN C-generation advance design decanter centrifuge. Two motors of GNLW363 centrifuge mounted on one end, parallel and at equal elevation for smallest footprint and maximum accessibility. The centrifuge Bowl material made from Duplex Stainless steel 2205 by centrifugal casting, which is better than SS304 and SS316. Stainless steel conveyor heat treatment to over 1000℃ for better strength. The opening on the conveyor does increase the capacity of the centrifuge. The centrifuge solids discharge port is protected by special ceramic inserts, it is anti-abrasive and with longer life time. Furthermore, GN equip bowl lifting bracket to protect the bearing during transportation.
3) 2 each Feeding pump for 2 each decanter centrifuge respectively
The feed pump is from German brand NETZSCH. Fluids touch material SS316L.
4) Electrical control system for all above equipments.
4) Mud tank, 1 ea, all above items mounted on the tank for turnkey solution.
For more information of GN made equipment, welcome you contact GN Group with its 7×24 hours service lines.

When we mentioned cutting dryer, there are always 2 meanings. One is for High G dryer (Hi-G dryer), or named as high G shale shaker or cutting drying shale shaker. It is normally used for water based mud drilling cuttings. It is a special designed shale shaker with high G force and up to 7.5 or 8. And the G force is adjustable to suit for more applications. High G cutting dryer is with a longer screen deck and screen area, mostly 4-panel.
Another kind of cutting dryer is vertical cuttings dryer (short name as VG dryer). Vertical Cutting Dryer uses centrifugal force to dry drilled solids from OBM or SBM . A stainless steel screen bowl traps “wet†solids and make them speed up to 900RPM with G force to 420G. It can also offer super high speed 1200RPM with G force to 750G. Liquid is forced through the screen bowl openings, while “dry†solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide surface welding protects the flights from abrasive and ensures long operational life. The purpose of this is maintaining a constant gap between the scroll and screen bowl, which is very important for proper operation.
In some cases, when people only mentioned cuttings dryer or cutting dryer, is means High G dryer shale shaker. And Vertical dryer is for vertical cuttings dryer.
Other waste management equipment used together with cutting dryer
High speed Decanter centrifuge
No matter high G dryer shale shaker or vertical cuttings dryer, after it, decander centrifuge should be used to separate the fine solids from the recoveried fluids. 14’’ decanter centrifuge is the most popular size. 18 inch and 22 inch big bowl is also normally used for big capacity. It is usually mounted on a telescopic skid and fed by a screw pump.
Screw conveyer
It is used to transfer drilled cuttings, feed for high G dryer shale shaker, vertical cuttings dryer. Screw conveyer can also used to transfer the drilled solids discharged from dryer to the collection position.

GN engineer just came back from a rig jobsite for the commissioning of GN drilling waste management dryer system for a Nigeria drilling company.
It is a reputable drilling company. All their rigs are big oil and gas drilling rig 1500hp. Mostly, they use OBM (oil based mud) or SOBM for drilling. WBM (water base mud) is not normally used. So waste management system is necessary for them. One the one hand, it is request by the company for environment protection. On the other hand, it can recovery drilling mud for reuse, and save their drilling cost on chemicals for drilling fluids. 
Drilling waste equipment GN offered to the Nigeria drilling company
