Vertical cuttings dryer & decanter centrifuge (high speed / big bowl) is the 2 most common equipment for drilling waste cuttings treatment. They are normally used together. Their main function is utilizing centrifugal force to separate solids from drill mud. But they have different applications.
Applications of Vertical cuttings dryer for drilling waste management
GN Vertical Cuttings Dryer utilizes centrifugal force to dry drilled solids in oil or synthetic base mud cuttings. It can also be used to treat water base mud cuttings. A stainless steel screen bowl traps “wet†solids and accelerates them up 900RPM with G force up to 420. Liquid is forced through the screen bowl openings, while “dry†particles are discharged by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life.
Applications of decanter centrifuge for drilling waste management
GN makes different sizes decanter centrifuge. There are 8 inch baby centrifuge, 14 inch normal size decanter centrifuge, 18’’ and 22 inch big bowl centrifuge. drilling waste management normally utilize high centrifuge force to separate fine solids. Take GN 14 inch decanter centrifuge for example, the max. speed is 3900rpm. Typical speed with load can reach up to 3200rpm, and the G force is 2062 @ 3200rpm. The separation point is 2~5 microns.
Difference of Vertical cuttings dryer & decanter centrifuge in drilling waste management system
Drilling waste management system, also be called drilling cuttings drying system. Vertical cuttings dryer & decanter centrifuge is the main machine of the drying system. With its patent design, GN vertical cuttings dryer can be used for oil base mud and water base mud, as well as SBM. With the same system, customer can treat all kinds of drilling waste cuttings.
In drying system, vertical cuttings dryer is used firstly to separate the coarse solids in cuttings. And the discharged solids is drying enough for truck shipment. Take GNCD930C dryer for example, when treat Oil base mud, after treatment, OOC can be reduced to around 4%).
After vertical cuttings dryer, there are high content fine solids in the liquid phase, decanter centrifuge is used to further separate the fine solids and reduce the mud weight.

GN exported a drilling cuttings drying system to Europe. The drilling waste management system is used to treat oil based drilling cuttings collected from oil drilling rig. Customs move drilling cuttings from offshore drilling rig to their yard for treatment. GN sent engineers to help them for commissioning and training their people for system running. The performance is good, customer is satisfied.
Equipment included in the drying system to Europe offshore rig
1) Vertical cuttings dryer: Model GNCD930C-VFD, Qty 1 each
Customer choose variable speed control panel for the dryer. The speed can be adjusted from 0~900rpm, while G force can be adjusted to max. 420G. Customer can choose the suitable speed per job site condition.
2) Decanter centrifuge, model GNLW363BG-VFD, Qty 1 each
It is a variable frequency control decanter centrifuge, with positive pressurized control panel for changing speed.
This decanter centrifuge is used to separate the solids from the liquid discharged from the vertical cuttings dryer. After separation by the GNLW363BG-VFD decanter centrifuge, the oil or water recycled from cuttings dryer can be returned to the active drilling mud system for reuse.
3) Mud tank skid for mounting above solids control equipment.
4) Screw conveyor ( Augers) for feeding the vertical cuttings dryer with the drilling waste and also for transporting the drilling cuttings discharged from the decanter centrifuge and the vertical cuttings dryer.
Below is the raw material comes from rig site. It is mixture of oil, cuttings and drill mud.
After treatment of GN drying system, the OOC on cuttings can be reduced to less than 4%.
Below is the solid phase separated from GN drying system.
As you can see from blow picture, after separation, the liquid is very dry and difficult for decanter centrifuge to treat. In order to make it flowable and possible for centrifuge treatment, customer dilute it and to further separate the fine solids above 2~5 microns.
GN Solids Control Drilling Cuttings drying system is popular around the world from Asia to Europe , and from America to Russia.

Vertical cuttings dryer is the main machine used to treat oil base mud drilling cuttings. It is normally used together with high speed decanter centrifuge, screw conveyer and Thermal Desorption unit.
GN brand Vertical Cutting Dryer utilize centrifugal force to treat drilling cuttings. For other brand vertical cuttings dryer, they can only treat oil base mud or or synthetic base, they cannot be used to treat water base mud. GN brand vertical cuttings dryer. with its patent design, can treat both water base mud and oil base mud, as well as synthetic base mud. And it can be used in most critical condition jobsite.
A stainless steel screen bowl traps “wet†solids and rotating them up to 900RPM with G force up to 420. 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 protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation. GN cutting dryer has been done strict balance testing for all major rotary components to minimize vibration & noisy.

Vertical cuttings dryer for oil base mud
As the necessary machine to treat oil base drilling cuttings, vertical cuttings dryer can reduce the oil on cuttings to 3~5%. Per Job site report, GN Second generation vertical cuttings dryer can reduce OOC (oil on cuttings) to 3.7% or less. It can greatly release the upstream processing machine capacity.
Compared with oil base mud, water base mud drilling cuttings is more critical for treatment. It is easy to block the screen basket and cause machine stop. GN second design vertical cuttings dryer with pressed air knife system for flushing the screen. It can be used to treat water base mud drilling as well. And the performance have been approved by job site test.

High G shale shaker can also used to treat water base mud. But it is not dry enough. With the high speed rotating, GN second generation vertical cuttings dryer GNCD930C can reduce the water on cuttings to a lower rate and make it easy for trailer movement.
