One set of GN Slurry Dewatering System for Construction Industry are ready for delivery to New Zealand. Features of GN slurry dewatering system including:
1) Complete package design to provide Turnkey solutions
2) We have rich field proven experience
3) 5 phase separation system to reach better treatment result
4) Modularized system for fast installation and flexible movement
Why we use GN slurry dewatering system?

We provide customized design, customized painting color, after-sales service and training of the client’s engineer. The solution is to use liquid and solids separation equipment to treat slurry from Hydrovac or HDD project, to collect reuseable material for construction and discharge the treated clean water. Normally the slurry should be contaminant free which is from horizontal directional drilling for replacement of underground pipes or other private construction.
The system is consist of several modular as below:

1. GNLMP1536 Mining vibrating screen modular, a mining vibrating screen installed on top of a mud tank, the coarse solids, rubbish, stones, branch, etc. big materials are separated out, and the slurry drop into the mud tank.
2. GNZJ706 Double deck shale shaker fine mesh modular, the double deck shale shaker is installed on top of a mud tank, a submersible slurry pump pick up the slurry discharged from mining vibrating screen and feed to the double deck shale shaker, the fine solids from the slurry are separated out by the top layer shaker screen and bottom layer shaker screen, totally there are 6pcs composite material frame shaker screens are utilized, total screen area is up to 4.63m2.
3. GNZJ594J-12N Desilter modular, the separation cut point is 20 microns.
4. GNLW553D Big bowl dewatering centrifuge modular, the mechanical separation cut point is 5 microns. With chemical dosing unit, the ultra fine solids can be separated out and get dry solids and clear water.
5. Chemical dosing unit modular

One batch of solids control centrifuge, vacuum degasser and shale shaker are ready for delivery to our Asia client.

Decanter centrifuge, vacuum degasser and shale shaker is our most popular solids control equipments, the shale shaker is the first phase cleaning of drilling fluids, the primary shale shaker will separate the drilling cuttings and reduce the solids content in the drilling fluids, the fluids dropped into the sand trap, the desander cone and desilter cone is the second and third phase cleaning of drilling fluids, the feeding pump of desander suck the discharged fluids from shale shaker and feed to desander cone, the feeding pump of desilter cone suck the treated fluids from the desander cone and feed to desilter cone. The treated fluids from desilter cone can be reused to prepare for new drilling mud in the mixing tank with mixing hopper and mixing pump, sometimes when silt accumulated in the drilling fluids.

Decanter centrifuge will be applied to separate the ultra fine solids, the clean fluids discharged from solids control centrifuge will be storage in a separate tank/ compartment, which will be used to prepare for new drilling fluids and reused by the drilling rig.
The decanter centrifuge produced by GN solids control can be high speed or variable frequency drive or fully hydraulic drive decanter centrifuge, the explosion proof standard CNEX, ATEX and IEC EX for option according to our client’s requirement. We can produce different size decanter centrifuge 9 inch, 14 inch, 18 inch, 22 inch with different bowl length as your required treating capacity. Except for drilling fluids decanter centrifuge, we can also produce decanter centrifuge for drilling waste management project, oil sludge treatment project, waste water treatment, dewatering unit application.

For more information of solids control decanter centrifuge, vacuum degasser, shale shaker, pls contact with GN solids.

Recently 10 sets of fully hydraulic drive decanter centrifuge for drilling mud cleaning are ready for delivery to North Africa.
The technical configuration is as below:

Model : GNLW363D-FHD
Bowl diameter: 14 inch (360mm)
Bowl length: 50 inch (1271mm)
The max speed is up to 3600rpm, the max G force is up to 2610G
The drive system is fully hydraulic drive system with adjustable speed, we use the reliable brand FHD system for reliable operation.

The Fully hydraulic drive decanter centrifuge can be utilized for oil and gas drilling solids control system, drilling waste management project, oil sludge treatment project, HDD mud recycling, , HDD tailing slurry dewatering, TBM slurry separation, construction engineering mud treatment, mining slurry separation, etc. Compared with VFD ( variable frequency drive) decanter centrifuge, the FHD centrifuge can be applied for heavy duty, simple operation, more flexible to meet the different working conditions.
Features of GN FHD decanter centrifuge:

1. The centrifuge bowl assembly use high level stainless steel material, duplex stainless steel SS2205 or SS2304 by centrifugal casting, which is superior to the performance of SS304 and SS316.
2. Multi speed balancing of different rotation parts to ensure the stable operation of the centrifuge under the high speed working condition.
3. Screw blade is protected by tungsten carbide tiles, which is adjustable once damaged. Compared with hard facing wear resistant coating, it can last longer and the further maintenance cost is cheaper for the long run operation.
4. The solids outlet and mud distribution port is protected by replaceable hard alloy sleeve.
5. The carbide scrapers to protect the bowl and prevent it from wear. The 360 degree rectangular slag discharge port for smooth discharge and avoid blocking the bowl inside.

Welcome to visit GN separation new factory to discuss your detailed requirement and check your equipments.

As a manufacturer of drilling cuttings auger in China, GN Solids Control produce different size screw conveyor with different length as drilling cuttings transfer equipment. GN screw conveyor is consist of drive end ( including electric motor, gearbox, coupling, frame, etc.), material discharge section ( including screw blade shaft, drive end assembly, etc.), middle section (screw blade shaft, hanging bearing, etc.), feeding section ( including screw blade shaft, feeding port, tailing end assembly) 4 part.

We have screw conveyor of 10 inch diameter, 12 inch diameter, 14 inch diameter, 16 inch diameter, 18 inch diameter, with screw length 12 ft per sections, we have 1 section 12ft, 2 sections 24 ft, 3 sections 36 ft, 4 sections 48ft for client’s different requirement. For the screw conveyor cover, we have option of steel plate cover and grating cover with highest safety standard to prevent objects for falling into the conveyor system to protect users.
Spiral conveyor is a continuous conveying equipment without flexible traction, which uses rotating screws to move the conveyed material along a fixed casing for conveying work.

The advantages of GN Screw conveyor are: simple structure and convenient maintenance; The overall dimensions of the cross-section are not big; It is possible to enter and exit materials at any position in the length direction; It is possible to achieve good sealing effect by tightly closing the cover of the casing. Therefore, screw conveyor are widely used in various industries such as food, medicine, chemical, papermaking, environmental protection, metallurgy, building materials, petroleum, power, etc., to transport various powder, granular, and small materials, such as coal ash, cement, sand, lump coal, grains, etc. There are many types of screw conveyors that can meet the conveying requirements of different working conditions and materials.
If you need a screw conveyor, pls contact with GN sales engineer to select a proper model.
