decanter centrifuge

Comparing with the most commonly used 14 inch decanter centrifuges, the GNLW452 and GNLW453 Decanter Centrifuges of 18 inch bowl and GNLW553 decanter centrifuge of 22 inch bowl are already called big bowl centrifuges. In this case, the newly on show GNLW764A-VFD Decanter Centrifuge could be a giant centrifuge, because the bowl diameter is 30 inch while the length-diameter ratio is 4.4 to one.

This design is suitable for handling the large capacity with a single unit of centrifuge. And the special design and best material chosen makes the GNLW764 decanter centrifuge to have a good performance and longer service life.
Besides GNLW764A-VFD decanter centrifuge, GN also has designed GNLW554D-VFD decanter centrifuge, which is also of large length diameter ratio up to 4, it is quite suitable for the waste water treatment projects.
Just like all of GN high standard decanter centrifuges, GNLW764 and GNLW554 decanter centrifuge share all following features:

GN BIG BOWL CENTRIFUGE

GN BIG BOWL CENTRIFUGE OF 30 INCH

1. Electric components are of Siemens, ABB or Schneider, all of world best brands.
2. For the VFD control panels, GN provide positive pressurized control panel and has air conditioning system for cooling as option.
3. Bowl main body material is made of duplex stainless steel SS2205.
4. Impeller protection is with tungsten carbide tiles, for longer service life and easier keeping the dynamic balancing.
5. Solids discharge port is made of special ceramic or tungsten carbide inserts, to have a longer service life.
6. Flexible adjustable liquid level ponds, to change the drying level of treated material.

Also, for the CIPPE 2017 which was held in Beijing, GN Solids Control also showed the fully hydraulic decanter centrifuge, of 14 inch bowl diameter. It is preferred by some clients from extremely high temperature condition and where the electric power is limited.

GN decanter centrifuges are widely used for drilling rig solids control system, the drilling waste management system, for the dewatering system, for TBM project separation works, and also for the oily sludge separation projects and soil remediation projects.
If you have any question or need more information, please fell free to contact GN sales team directly or visit GN factory near Beijing, Capital of China.

Mud Agitator is one of the solids control equipments that are mainly used for you to mixing the drilling body fluids in the mud tanks to hold the solids inside the drilling fluids suspending other than sedimentation down to the tank bottom level.
GN’s sales team ever gotten many inquiries on the mud agitators; unfortunately, most of the buyers have no idea on how to choose the right product suchs mud agitator, shale shker, mud cleaner, decanter centrifuge, etc. for their project and even seldom know how to use the equipment adequately to ensure a longer life time. GN’s sales are good at comprehension clients’ specific request simply by asking few simple concerns. With the answer from the buyers, GN always could provide the best proposal for clientele. Now let’s see precisely what these questions are and exactly information GN need to give you a proposal.
a. What is the on the inside dimension of the mud tank or pit. From this concern, GN will know the inside duration, width and depth in the mud tank, and then GN will know how long the agitator shaft should be suggested to get clients and how big impeller should be used. For the deeply mud tank or ditch, the stabilizer will be presented to hold the agitator length for stable performance.

c. What is the shape of the mud tank, cylinder or square? Then GN will know tips on how to design the mud agitator.
chemical. What is the electric specification, generally GN would like to know the work site electric voltage and occurrence. Different countries may have various frequency, the 50 Hertz motor cannot be used beneath 60 Hz, and protection is ever the first believe we should keep in mind.
d. Will be S. G. of the chemical? For very thick water, GN will propose greater horse power motor to drive the particular agitator.
For some clients who have get the mud agitators through GN and make the mud tank by themselves, GN often recommends them to make the mud tank with same way of measuring, thus they can get the agitator all same model, which will be much better for clients’ future maintenance. GN advise the RPM setting on the mud agitator between 40-96, too high will disturb the actual solids suspending, while lacking will lead to solids sedimentation.

We have one consumer from Africa; require products & services for Winter Desorption Unit (TUD). Your customer gives requirements as down below:
1) Leak proof skips and waste oil aquariums (i. e., offshore mobile tanks) for the collection of
NAF drilled cuttings and other NAF rig wastes at THE CLEINT’s drilling rigs.
2) Pier access for PSVs supplied by THE CLEINT.
3) Dockside services (i. e., employees, cranes, and forklifts) intended for loading / offloading skips/waste oil tanks from the PSVs and loading the skips and / or waste oil fish tanks on trucks.
4) Passenger trucks for hauling the skips and / or waste oil storage containers to and from the treatment center and within the treatment facility and with hauling treated residue in the treatment facility to the landfill.
5) Treatment facility for the thermal digesting of NAF drilled cuttings and other NAF rig toxins, including any containers essential for transporting the treated silt to the landfill. Treatment facility should certainly have sufficient space to support filled skips and shop empty skips until indexed by THE CLEINT. Treatment facility should certainly have capability to recover, retail store and transport base essential oil from treated cuttings for the dock
6) Hazardous waste materials landfill for treated deposit disposal.

As we are genuine solids control and drilling waste management equipment producer, we cannot offer the services. But we recommend specialist drilling waste management vendor to them. In this case, we can cohesiveness with the Service Company, and give very good equipment and service to the bottom user.
The main equipment stated in the project is heat desorption unit (TUD), GN can offer mobile thermal desorption unit (TUD), including Serving Hopper, burner, thermal desorption unit, cyclone dust parting, vapor recovery unit, essential oil water separator, water tank, cooling tower, water screen duster, condenser, process control etc .
Except for TDU, GN Solids Control also create all line of solids control equipment, eg. Shale shaker, decanter centrifuge, mud cleaner, agitator, centrifugal pump, 1000gpm mud cleaning system, 500gpm mud system etc .
