3 The control panel utilized in zone 1,exp standard is Eex deⅡBT6.
4 The centrifuge used in ATEX EX zone 2(CAT 3G), TEMP T3 hazardous area.
5 Erosion affected area to be protected with abrasion protection –Tungsten Carbide coated stainless steel parts.
6 Include a signal line, with equipment fitted for a local/remote switch and a signal stating to the remote locatation(SPDT contact) LOCAL status which shall block any remote functionality and a similar stating remote status which likewise shall block any local actions.
7 Nominal treating capacity is 40m3/h,actual treating capacity is 30m3/h.

Last week we shipped another set of decanter centrifuge to South America. GN solids control is a new star for South America market, there are several sets of centrifuge working in site in Colombia. Our improved high speed centrifuge GLW360x1250 has been proved in good performance in solids liquid separation.
 solid liquid separation centrifuge GN improved decanter centrifuge has the following features:
G-force 2035G, separation point 2~5μm, differential torque 4000N/m max, bowl speed( during working) 3200rpm, differential ratio 57:1.
Bowl
The bowl has a cylindrical/conical shape and rotates at a pre-set speed optimal for the application. The slurry rotates with a different scroll design or by modifying an existing scroll. Scroll pitch and single or multiple flight configurations are important design variables.
Scroll
The scroll rotates at a slightly different speed than the bowl and conveys the deposited solids toward the conical end of the bowl.
Materials of construction
GN solids control uses high-quality stainless steel for all wetted areas. Bowl and scroll castings are made from centrifugal cast high strength and corrosion resistant stainless steel.

Generally speaking, decanter centrifuge plays a role in separating solids from liquids. Alfa Laval decanter centrifuge is one of the best sold centrifuges in the world, especially in South America. The other brands in South America market including Derrick, MI-Swaco, NOV, Derrick, GN, etc. GN solids control is new brand player in the market, but fast developing.
 decanter centrifuge to Ecuador How a decanter centrifuge works
A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity.
When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid – the so-called pond – as required.
The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually “ploughed” out of the pond and up the conical “beach”.
The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl. Baffles within the centrifuge casing direct the separated phases into the correct flow path and prevent any risk of cross-contamination. The speed of the screw conveyor may be automatically adjusted by use of the variable frequency drive (VFD) in order to adjust to variation in the solids load.

GN solids control have VFD decanter centrifuge for sale. Welcome to inquiry us for drilling fluids decanter centrifuge GLW-V-355x1250N .
 decanter centrifuge for sale GN decanter centrifuge mainly used for drilling fluids processing, barite recovery, drilling waste treatment, mud weighted, etc projects. We also produce related equipments fitted for the centrifuge, to be assembly as a complete drilling mud processing system, including mud tank, mud agitator, mud mixer, shale shaker, etc.
- Anti-overload
The device protects the Compensating gear from torque overload, which is installed in the outside end of the Compensating gear. The torque of gear is limited with a spring clutch by which power can be imputed. While overload cuts off spring clutch with driving shaft, the face of spring move the gland down to outside for 6mm and the stroke faucet switch on to switch off the power of main motor and fluid supply pump.
- Electric interlock device (only dual motor driving system)
In the dual motor driving system without inverter speed-adjustable device, the correct program for starting a centrifuge is:
1) Firstly start the auxiliary motor.
2) After thirty second, the main motor allows to be started.
The correct program for stopping a centrifuge is as follow:
1) Firstly stop the main motor.
2) After ten minutes, the electric interlock device will automatically switch the power of the auxiliary motor.
With the electric interlock device, the correct program can be automatically carried out and unexpected result from wrong operation can be avoided.
- width rotary speed to satisfy technical requirement;
- Smooth and silence when start;

GN decanter centrifuges are widely used in complete drilling fluids recycling system, work together with cutting dryer. Such drilling fluids circulation system is widely used in Venezuela and other South American countries.
Venezuela’s proven oil reserves are among the top ten in the world. Today, Venezuela is the fifth largest oil exporting country in the world with the second-largest reserves of heavy crude oil (after Canada).
 drilling fluids decanter centrifuge There is big demand of oilfield drilling mud system/solids control system in Venezuela. Before they mainly purchased the drilling mud system from USA . But now more and more clients realize that they can purchase rig packages from China, although the delivery time and transportation will be longer and complicated, they can save a considerable drilling cost.
A complete drilling fluids circulation system including shale shaker, mud cleaner( or separate desander, desilter), screw conveyer , Cutting dryer, recycling mud tank, decanter centrifuge(with feeding pump), drilling mud reserve tank/storage tank, etc.
After processed by cutting dryer, the large drilling cuttings have been separated out, the drilling fluids flows to recycling tank or to decanter centrifuge through screw pump. Since decanter centrifuge has higher separation factor than cutting dryer, it can separate fine particles from the drilling fluids and recycling barite to keep the drilling fluids balance.
GN decanter centrifuge features:
1 Stainless steel cover

GN developed a new Oilfield Drilling mud centrifuge LWF600x1000N, since more and more clients inquiry relatively larger centrifuge for oilfield drilling to meet various requirement.
Max treating capacity: 300gpm
 Oilfield Drilling mud centrifuge Normal treating capacity: 264gpm
Average bowl speed: 1800rpm
Bowl diameter: 23.6”
Bowl length: 39.4”
Total power: 52.5KW
Matched pump power: 5.5KW
Previous model decanter centrifuge LWF450x1000N
Max treating capacity: 264gpm
Normal treating capacity: 220gpm
Average bowl speed: 1800rpm
Bowl diameter: 17.7”
Bowl length: 39.4”
Total power: 37.5KW
Matched pump power: 5.5KW
Compare with LW450x1000N, LW600x1000N has larger treating capacity and larger bowl, which can process more drilling fluids in one time and less drilling cost relatively. They are both middle speed decanter centrifuge, which can separate drilling fluids solids particles 5~7 μm, for some clients, it is enough for drilling fluids cleaning, but for some other clients, they need a high speed centrifuge to separate more fine solids from the drilling fluids, we will recommend GLW355x1250N or GLW-V-355X1250N. The max treating capacity is 176gpm.
Sometimes you will encounter troubles when operate the centrifuge in oilfield, we would like to offer some suggestions for normal problems, anyway, we will have a engineer to service if complex trouble.
