Several notices to use GN decanter centrifuge
As more and more GN decanter centrifuges are using in the oil and gas industries for the drilling fluids management and water recycling, GN decanter centrifuges are helping more and more clients to protecting the environment.
Now GN Solids Control is manufacturing about 250 sets to 300 sets every year, most of these decanter centrifuges are using over abroad. In order to fulfill customers’ demands, GN usually sends out our engineers for the after sales service. 

There are several things that the operators need to know:
1. The wire connections need to be fully correct. Any wrong connections may lead to the damage of decanter centrifuge, and the separation work can not be reached.
2. The liquid discharge port should not be changed without allowance. For uncertain situations, we recommend to place a catching tank in the bottom of the liquid discharge port. Once the pipe connected with liquid discharge port is too small, fluids will be flooded from the small end and the VFD control panel will give a stop signal to the main motor for protection.
3. The initial feeding capacity should be too large. Although GN decanter centrifuge can deal with 130 GPM, different OBM or WBM has different density so the treating capacity is not always the same. For the clients have no idea about the feeding capacity, we recommend to give a relative small feeding capacity at first. If the solids discharged from the solids port is pretty dry, the feeding capacity can be increased. On the other side, if the solids with too much oil or water after being treating by decanter centrifuge, the operator should decrease the feeding capacity a little bit.
4. Clean the decanter centrifuge thoroughly after you finish the separation work every day. Keeping feeding some clean water into the centrifuge, some solids left in the collection box will be cleaned. And after the cleaning, spin the centrifuge manually to let the inside water come out.  

The Operation of GN Variable Decanter Centrifuge
GN Solids Control has been working on designing and manufacturing decanter centrifuge for many years. Now there are about 250 to 300 sets decanter centrifuges are provided by GN to over 60 countries.
GN has upgraded their decanter centrifuges to the third version; all the modifications and upgrade are all made carefully by the experiences gained in the worksite. GN technicians are devoted to give the best solutions for worldwide clients. Until now, GN is the first Chinese manufacture that can provide decanter centrifuge and cuttings dryer together. With many years and thousands successful projects, GN are providing the more and more perfect solids control equipments (shale shaker, mud cleaner, decanter centrifuge, cuttings dryer etc).
In order to use GN decanter centrifuge well, today we would like to share you some info on how to operate it.
Before testing running, the operators need to disassemble the fix belts and supporting brackets on the bowl. All the belts and brackets are used for safety transporting. GN provide stand to support the whole decanter centrifuge in a proper height. Operators need to find a good locate the decanter centrifuge with stand. 

All the wires that connected to the VFD control cabinet is using air plug, and the four inside ports are used for connecting the power lines and ground line with the VFD control cabinet. Make sure to put the four ports in a right direction first. 

After read the decanter centrifuge carefully, you can run it according to the instruction. Check the rotating direction of the two motors, and make sure they are running the same direction as the red arrow showed on the case of the motors.
For the second version decanter centrifuge, you need to flush the rotating bowl and propeller some time after finishing the separation every day. Generally speaking, most of the decanter centrifuge broke down are caused by solids blocked in the bowl.  
Lubricate the necessary parts as the instruction says. A good maintenance can help to expand the life span.
Whenever you have problems, feel free to contact with GN immediately.

Thepurpose of decanter centrifuge is performing separation ofsolids from liquid.
For various reasons, liquid often contaminating with many solids objects
and some type of solids objects are harmful.
The decanter centrifuge use principle
of gravitational force through continues rotation in
vertical, horizontal and conveyor centrifuges.
Depending the RPM of the decanter centrifuge motor, it can produce the
rotation force in 1000 times and beyond on normal gravitational force. The separation time need it from minutes to
hours. The bowl tube that equip with
internal conveyor rotate in extreme high speed that moves in same direction but
at different velocity to achieve solids separation from liquid.

Many
industrial job use decanter centrifuge to perform separation and purification
purpose, some examples are environmental, medical, chemical, food, oil and gas
industry are commonly use this method for different purpose but achieve same
goal: the separation of solids from liquid. In fact, without this step of process, these
industries will not achieve more specific tasks because it is the most the
first step of process.

These
are steps of how decanter centrifuge separate solids from liquid:

1.      
The mud is enter the centrifuge
from connection of pipe

2.      
By an internal feed space, the conveyor push the
mud through a nozzle into the bowl

3.      
The rotation of bowl in high speed that makes
gravitational forces

4.      
High rotation speed separate solids from mud in
times

5.      
The conveyor makes solids upward and discharged

6.      
Solids removed
and clear water released from different output

The ability to purify
a liquid makes decanter centrifuges ideal for waste water treatment facilities.
However, there are varieties of industries for which such centrifuges play an
important role. Similar to other decanter equipment, centrifuges are simple to
install or use as stand-alone machinery that do not need permanent mount.

GN takes necessary measures for transporting protectionGN Solids Control has one branch company in Houston, TX. Some solids control equipments such as GN Shakers, GN mud cleaners and GN decanter centrifuges as well as some other spare parts such as GN shaker screens, GN mud guns, GN mud agitators are also stored.Experienced engineers have been sent to Houston branch for the after sales service and training work. GN is trying to provide excellent after sales service in the America market.Now all the solids control equipments are manufactured in Chinese factory in advance, then they are shipped to Houston warehouse. In GN Solids America warehouse, GN engineers will do some assemble work and test running work, every equipment will be fully tested before they are transported to our clients’ worksite. 

As many parts are quite vulnerable in transporting without some protecting measures. The principle of GN solids control is providing the brand new equipments with best quality. So GN engineers will take some necessary measures to keep solids control equipments in a very good condition.
Take GN decanter centrifuge as an example, due to the rotating bowl is quite heavy the two supporting bearings will be destroyed when its keep rotating on the way. So GN engineers will use two cloth belts to tighten the rotating bowl, and two steel bows are supporting the bowl and lighten the heavy load for the two bearings.
The Cover of the decanter centrifuges will be locked with bolts before transport. In order to move the decanter centrifuge conveniently, GN engineers fixed it on a wooden pallet. Some parts will be fixed on the pallet such as discharging port. VFD control panel will be located on a wooden pallet just like the decanter centrifuge.
Some other equipments such as shale shakers, they will be fixed tightly with large bolts in case they are vibrating during transporting.

GN Dewatering Unit with Flocculation System
As the fast development of GN Solids Control, GN has provided many sets of solids control systems to clients from various industries. Recently, GN got many inquiries on waste water management, some clients need to separate the clean water from drilling mud can d reused the water.
Although different projects are customized by different working situations, the working principle is pretty the same. Just take one of the dewatering unit that GN Solids Control provide several months before as an example.

This GN Dewatering Unit is composed by the following equipments:
1. GN Double Deck Shale Shaker
It’s used to separate solids that larger than 100 microns. Here we use GNZS706E-HB.
2. GN Desander
Desander is one type of shale shaker with large cylones, which can be used to separate solids larger than 50 microns. Sometimes, GN recommend to use desilter which is equipped with small cylones and can do much finer separation.
3. GN Flocculation Unit
The flocculation is used to add polymers into drilling fluids which can help to collect small diameter solids.
4. GN Decanter Centrifuge
The drilling fluids come from flocculation tank can be further separated by GN decanter centrifuge, which can separate the solids larger than 2 microns.
So after all the treatment by the above solids control equipments, clean water can be separated from drilling fluids or waste water and this clean water can be reused. For some strict demands, such as the discharged mud need to be pretty dry, GN Solids Control recommend to use vertical cuttings dryer.
By using GN vertical cuttings dryer, clients can deal with oil base mud (OBM), water base mud (WBM) and synthetic water based mud (SBM). GN has provided many sets of cutting dryer for mud separation. Based on the working performance, the oil can be separated to below 5% and the water can be separate to below 10%. For details, welcome to contact thomas@gnsolidcontrol.com.

Lately, Hebei GN Solids Control Co., Ltd, a specialist of drilling waste management system, has arranged the shipment of 1 unit of drilling cutting drying equipment to the West African customer. GN solids control is the first API solids control and drilling waste management equipment manufacturing company in China, and it has sold items to in excess of 60 nations. This isn’t the first order but a repeated order following the customer using GN product. Using the passing of environment rules, just about all drilling cuttings have to be dried to lessen pollution before discharge.

 The order that the customer required about the equipment shows up as below.

 1 unit GNCD930 vertical cutting dryer having a maximum speed of 900 Revolutions per minute along with a maximum G force up 420 centrifugal G force.

 2 models GNLW363 series 3200RPM high-speed decanter centrifuge with duplex stainless material on rotation bowl and screw propeller paid by tungsten carbide tiles.

 3 models screw pump sitting 30 cubic meters each hour for the use of feeding drilling liquids to decanter centrifuge and pressure washing for that vertical cutting dryer. Generally, the vertical cutting dryer is outfitted having a flushing pump to transfer waste water that is clean to purge screens.

 The Kodak play touch camcorder of drilling cuttings drying devices are to process the cutting that are separated in the mud with the first stage equipment-shale shaker and 2nd stage equipment mud cleaner. After released from shale shaker and mud cleaner, the cuttings is going to be directly moved in to the vertical cutting dryer via a screw convey or perhaps a hose pump, the liquid is going to be retrieved again, as the solids will end up dry enough to become released. GN drilling cuttings drying equipment happen to be offered to African nations like Egypt, Libya, Algeria, and Nigeria. The performance is pretty well. Welcome your RFQ of the drilling cuttings drying equipment.

How to choose GN decanter centrifuge based on rotating speed

GN Solids Control Co. has been working on solids control and drilling waste management systems for many years, there are clients from over 60 countries are using GN products. With the fast development, GN moved to the new factory near Beijing several years ago, and GN has been building another factory which is quite near the current factory.

Last year, GN has established two branch companies in America and Russia, GN is working on the storage of solids control equipments and spare parts in these two branch companies. Right now, GN Solids America has 4 shale shakers, 2 mud cleaners, 2 decanter centrifuges in Houston warehouse, some other spare parts are also kept here.

As GN decanter centrifuge is quite popular, we have sold about 250 sets every year. Today we would like to give you some brief introduction on how to choose GN decanter centrifuge based on the rotating speed. The rotating speed as well as differential speed is quite important for the performance of decanter centrifuge. The largest rotating speed is not always the best solution.

1. For barite recovery, you can use GNLW452 at the rotating speed of 1800 RPM, while for GNLW363 you can use 2200 RPM fix speed.

2. For high gravity solids separation, we recommend to use GNLW452 or GNLW363 at the rotating speed of 2700 RPM. If equipped with cuttings dryer, you can use GNLW363 with 2700 RPM pulley.

3. For low gravity solids, we recommend to use GNLW363 equipped with the 3200 RPM pulley.

4. For solids control system, one set of GNLW452 and one set of GNLW363 is totally OK, the rotating speed can be 2700 RPM or 3200RPM.

5. It’s obvious that you can choose variable speed decanter centrifuge if you are not very clear about the solids condition. And you can change the rotating speed quite conveniently when the solids condition is changing at the same time.
