GN Full Series Decanter Centrifuge for Different Applications

Decanter centrifuge is main equipment in GN’s production line. Based on the most popular model 14 inch decanter centrifuge used in oil and gas solids control system, GN developed several models decanter centrifuge that could be used for different applications.

GN’s 9 inch decanter centrifuge model of GNLW223 is bowl diameter of 9 inch and the designed capacity is 6 cubic meters. With a high working speed up to 3800rpm, this model is always used for fine solids removal. As it has small capacity, it is often used in diamond core drilling for geology research and some other mining projects.

GN’s 14 inch centrifuge is widely used in solids control system and waste waste management system. GN uses material of SS2205 as the bowl material for a better dynamic balance. The protection of screw propeller is using bolted tungsten carbide tiles thickness of 4mm for longer lifetime. This model is both fixed speed and VFD model for customer’s option. Low speed used in traditional solids control for barite recovery and high speed model used for ultra fine solids separation and waste cutting management. 

GN’s 18 inch decanter centrifuge is mainly in Mud Cleaning System system for barite recovery, it has a relative low speed of 2000rpm that is the best speed for this job. GN has two configurations for this 18 inch centrifuge with different material, speed and driving method. Economic type is especially for the customers who want to save on the equipment cost.

GN’s 22 inch decanter centrifuge has designed normal capacity of 90 cubic meters, which is an ideal choice for large flow rate project. One of GN solids control ’s 22 inch centrifuge unit ever been used in dewatering unit for flocculated fine solids separation. The long bowl can provide a long time for separation for a better expected result.

GN’s decanter centrifuges are always assembled with other equipment like shale shaker units or cuttings dryer unit to become a modular system for multi-function application. Any interests on GN’s centrifuge unit, feel free to contact with us.

Drill cuttings solidification unit unit for drilling waste management

As more and more governments issued increasingly more strict regulations on the envornment protection, drilling waste management equipment becomes more and more required at drilling rig website, especially at oil and gas drilling rig site. As the drilling fluids contents various type of chemicals, if discharged straight. it will have very bad air pollution to the environment.
GN Solids Control latest design drilling waste management equipment drill down cuttings solidification unit tend to be welcomed at jobsite.
1) The drill cuttings renforcement unit can be used to treat drilling cuttings discharged from the higher G drying shaker. Once the cuttings from solids control shaker, desander, desilter handled by high G drying shale shaker, the fluids should go to drying shaker capture tank for further treatment, the actual solids from high Gary the gadget guy drying shaker can be treated through drill cuttings solidification device.
2) The drill cuttings solidification unit can be used to deal with drilling cuttings discharged through decanter centrifuge. The fluid phase will be covered by additional treatment, like dewatering device. while the solids phase can usually be treated by drill cuttings renforcement unit.

3) The solids discharged from vertical cuttings dryer can be further handled by drill cuttings renforcement unit. It can reduce the drinking water content in the waste.
Many consumers may wonder, what is the drinking water content after the drillings handled by drill cuttings renforcement unit? It is not easy to see the particular water content is. Currently flexiable. It is controlled by the providers. If you want to make the cuttings dryer, you add more chemical substances, if you do not need very dryer, you can reduce the quality associated with chemical.
Features of GN most recent design drill cuttings renforcement unit

How to design VFD Control Panel for Decanter Centrifuge

The drilling mud decanter centrifuge driven by VFD will give many benefits to the clients. The adjustable bowl speed and differential speed allows the operators to set the right G force and solids pushing speed according to the drilling mud conditions.

To design the VFD Control Panel, the contractor needs the power supply specifications. Normally it is 460V/60HZ for USA standard or 380V/50HZ for Europe and China standard. Than the pulley size of the motor and bowl side will decide the bowl driving speed at different frequency. After confirming the bowl speed formula, the contractor needs the formula for calculation of the differential speed. For GN Decanter centrifuge, the Sun-Wheel gear box ration is 57:1. So the differential speed will be the bowl speed minus the gearbox input speed and divided by 57.

For the VFD Control panel, there is different explosion proof standard. In China, it is CN Explosion proof which is close to IEC Ex standard. In Europe, it is ATEX Explosion proof. And in North America, the explosion proof standard is UL for USA, and CSA for Canada.

GN Pressurized VFD Decanter Centrifuge control panel is specially design for Zone 1 or Zone 2 standard with ABB VFD and stainless steel cabinet. The PLC smart control allows the user to operate the drilling mud decanter centrifuge by HMI screen.

GN VFD decanter centrifuge has been exported to over 30 countries and regions, GN Solids Control VFD decanter centrifuge is available in different sizes including: GNLW223C-VFD (9inch) bowl, GNLW363C-VFD(14inch bowl), GNLW453C-VFD (18inch bowl), and the big bowl big volume centrifuge with 22inch bowl and model is GNLW553C-VFD.

To support the worldwide operators, GN Solid Control keep expanding our branches, now , GN service and support are available from Beijing, China, Houston, USA, and Russia. Some other areas are covered by GN local partners who are the professional solids control service companies.

Small Decanter Centrifuge Brought GN a New Broad Market

Within GN’s centrifuge production collection, there is a model GNLW223 also is called Mini decanter centrifuge with a bowl diameter associated with 9 inch and twenty six inch long. This small centrifuge is mostly used in gemstone core drilling and some some other small drilling projects. Really, it is a very casual chance for GN to start the production of this mini decanter centrifuge. However , it is unexpected this model brought GN an extensive market in a new business.
GN Solids Control started nearly 10 years ago like a manufacturer of drilling liquids recycling equipment and system. Most of GN’s equipments are utilized in oil and gas drilling business. At that time, most China created decanter centrifuges used in drilling mud system are dish diameter of 18 " with a speed around 2150 RPM. This type centrifuge is a perfect model for barite recuperation.

While at the same time, the imported centrifuges used in China oilfield offers diameter of 14 " with a speed up to over compared to 3000 rpm which could take away the find solids down to five microns from the drilling liquids. No doubt, most of GN’s réflexion are focused on the centrifuge used in oilfield.
One day, GN received an inquiry associated with decanter centrifuge used for gemstone drilling solids removal. That period, GN was much unacquainted to this industry. Look back again, we can definitely say that all of us made a great and correct choice that time. Based the actual technology of manufacturing the centrifuge used in oilfield, GN created the first 9 inch centrifuge for this client coming from a primary drilling company. Luckily, this particular unit pasted the test as well as won GN good suggestions from client
Before the production of this unit, GN actually didn’t know what is gemstone core drilling. Nowadays, you will find already 16 units GN’s mini decanter centrifuge roaming Canada, 3 units in the us and 2 units gear on solids removal device working in Chile. More and more customers in this industry come to GN and show their interests to create business with us on this small decanter centrifuge. This small centrifuge has already been one glowing point in GN full creation line, and its onsite overall performance is proved. The chances are usually there, and are you prepared to grab it?
