GN Solids Control centrifuge is widely used in different field application. Recently, we have 3 sets of centrifuge ready for delivery to Middle East. 1 set big bowl big capacity variable speed centrifuge GNLW553-VFD, 1 set high speed and fixed speed centrifuge GNLW363BG and 1 set high speed and fixed speed mini centrifuge The customer use the centrifuge for oil sludge treatment.

22’’ centrifuge GNLW553-VFD – Big bowl big capacity

GNLW553-VFD is the big bowl centrifuge from GN Solids Control. This is mainly used for fast drilling cut mud weight or micro tunneling projects. It can also be used for fine/ultra fine solids separation, barite recovery and zero-discharge dewatering.

GNLW553 centrifuge only variable speed available. The centrifuge can start with one separate VFD control panel. The centrifuge can start from 0 to 2500rpm smoothly and will not arouse very big momentary current. A 200kva generator is OK.

GN Solids is the leading manufacturer for decanter centrifuge. They have different type centrifuge for different applications.  Recently, GN Solids just finish the CIPPE oil show in Beijing with their latest patent decanter centrifuge. On the show, many visitors come and show keen interest on GN PLC display screen, positive pressurized control panel.  Two big visitors check GN factory after the exhibition and release Purchase Orders on decanter centrifuge and vertical cuttings dryer.

What is Barite used for

Barite is commonly used to add weight to drilling fluid. Barite is of significance to petrophysicists because excess barite can require a correction factor in some well log measurements.

Barite Recycling centrifuge

GNLW452S centrifuge is an ideal choice for barite recycling centrifuge, it has been used in oilfield in Russia and middle east for barite recycling. Its max rotary speed is 2200rpm and max separation factor is 1220.

Barite recycling centrifuge is also called low speed centrifuge. Its separating factor is 500~700. To low-density solids, its separating point is 5~10μm. To high-density solids, its separating point is 4~7μm.

Barite recycling unit

High speed centrifuge’s separating factor is 1200~2100 or so, separating point is 2~5μm, it is usually connected with low speed centrifuge to make up a dual centrifuge system. In the system, barite recycling centrifuge is installed in the first phase, barite separated from it is discharged into mud tank to be recovered, liquid is drained into a surge drum first, and then be sent by a pump to high speed centrifuge; the solid separated from high speed centrifuge will be discharged out of the tank and the liquid is back to recirculation system. GNLW363VFD centrifuge can be also used for barite recycling, you can control the speed to 1500~1800rpm by variable frequency drive control panel, when you need to separate more fine solids, you can adjust the speed to 3200~3500rpm.

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.

Safety Device of GLW-V-355x1250N decanter centrifuge

  1. 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.

  1. 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.

GLW-V-355x1250N Advantages:

  1. width rotary speed to satisfy technical requirement;
  2. Smooth and silence when start;
  3. Continue reading »
