HDD is short of horizontal direction drilling, it is one kind rig machine that can directly drilling underground and will not break the ground surface. That is widely application on municipal project, such as the underground electrical wire system ,city drainage system. According to different project situation ,there may will use the drilling mud to cool rig and carry out the drill cutting from the tunnel. Compare with oil well drilling mud, this mud is easily to treatment.

Last week, we delivered one set HDD mud recycling system to out client. In this system, it include one 1000gpm/hour mud treating unit, jet mud mixer and mud tank. The mud treating unit is the main product to separate the drilling mud ,the unit has two 10 inch hydrocyclone mounted on GNZS706 shale shaker. Actually this unit can be individually used as mud treating system. GNZS706 is two layers shale shaker, pump feed the slurry in to the bottom layer shaker screen for first stage treatment, it can remove out the big size particle. The liquid will drop to the bottom tank through the shaker. The other centrifuge pump will suck the liquid from bottom tank into the hydrocyclone. In the hydrocyclone treatment ,the clean liquid will be discharged from big end to other tank for recycle. The separated solids will discharged through small end and drop on the up layer screen for further separation. Solids be move out and liquid go down the bottom tank. The drilling mud after the whole program separation, it will clear enough for reuse.

 We also equipped one mud jet mixer in this system. The operator can dump the mud material into the hopper, through the venturi structure, the mud material will be sucked and mixed with water, and then pump into the mud tank.

Mud recycling not only be used in trencheless project, but also in tunnel boring, piling project etc. GN can provide the whole set solution according to client requirement. We will be pleased to share our experience if you have demanded on these separation equipment. 

GN Solids America was funded in 2013, as branch of GN Solids Control, it main provide service to north and south America market for quick response. Not only a office , we also built warehouse in Houston to reduce the shipping time. GN main produce separation and conveying equipment for different industries, especially in the drilling, our equipment get good reputation with stable quality. Not only separation equipment, GN centrifuge pump,screw pump ,submersible pump these equipment as corollary equipment of separation system, they are also popular in the market, especially the vacuum pump.

Last week, we delivered several sets vacuum pump to Houston warehouse. It is different with the normal pump ,it used to transfer the material with high solids content or solids particle that smaller than 50mm, such as the drill cutting, waste water from mill, cement etc. Vacuum pump is driven by air. The transfer capacity can reach 10m3-40m3 depend on the material density and viscosity. Pump empty the air and generate suction force , the material will be suck in to pump body. Then the air compressor will convey high pressure to the pump and push the material to discharged port. The pump max suction distance can reach 50 meters, and max discharge distance can reach 500-1000 meters.It is long suction and discharge distance, but the pump suck depth is less than 12 meters in vertical. This limit some client to use it transfer sludge from deep pit.

As we know, only 3 companies in the world can manufacture this kind pump. And GN Solids America LLC is only vendor to provide this pump. Even so,GN price is very reasonable and competitive compared with some other pump supplier. With the widely application , GN vacuum pump are known by more and more people , we improved our inventory to make sure the quick delivery. If your project have demanded on this pump, please contact us.

GN Solids Control has been funded for more than 14 years. From the date of establishment, we are focused on the solid control industry and serve the drilling company and oil gas company , and help them solve the drilling mud treatment problem. In oil well drilling, the mud is very import middle material to cool the rig and carry out the drill cutting from well. It almost use the solids control system to finish this treatment.

As we all know, the mud system has several different kind equipment and mud tank. Which need many pump to transfer the the slurry from different tank. Centrifuge pump is the most common be used for in solids control system. At beginning, GN design the system ,and purchase the pump from other supplier for our solids control system. But the quality is not stable. Then we decider to make our own brand centrifuge pump with stable quality.

GN decanter centrifuge is one kind equipment with simple structure and stable quality. The pump connected with a electrical motor, through the motor drive the impeller to reach the slurry transfer. It can transfer the slurry with high solids content, but we need to note high solids content material will speed up the pump wear, especially the impeller. Centrifuge pump has not the ability that suck the material , the liquid level need to higher than suction port.

In the centrifuge pump , which has many spare part, so it will need supplier can provide the part quickly when client maintain the pump. Considered this point, GN decanter centrifuge spare parts are 100% interchangeable with Mission Magnum. Client can get the parts from GN ,or directly use Mission part. That will be convenient for client to repair the pump.

GN centrifuge pump have several kind model from 11kw-75kw with flow rate 45m3/hour to 320 m3/hour. Client can choose according to the requirement. For America user, you can directly purchase from our Houston warehouse and also the after sale service. GN centrifuge pump is stable with competitive price.

Hydrovac excavation is one popular in developed country. It utilized the high pressure water flush the ground and finish the excavation. Compared with normal excavation method, it is high effective, will not damage the pipeline under ground, and also the sludge will be sucked by hydro vac truck, so there is no pollution. However, the collected sludge always the big problem for treatment. GN dewatering system is specially used to treat this kind sludge. Last week ,we delivered 1 set dewatering system to our New Zealand client.

In this dewatering system, this will include mud catch hopper, coarse shaker ,mud cleaner and decanter centrifuge. As we know ,the sludge will be collected by hydrovac truck, the catch hopper make it easy that truck can directly dump the sludge into the hopper. It will improve the efficiency and prevent the splash. The catch hopper will feed the sludge into coarse shaker. The sludge always include some big solids ,such as gravel ,plastic, stone etc. Coarse shaker can separate out these big size solids, and finished the first stage of classify.

The liquid after coarse shaker will be feed into mud cleaner , through the the hydrocyclone , the solids that bigger than 40 micron will be remove out . In this step, the solids content will down to 20%. This is very import for the next separation stage by decanter centrifuge. Because the high solids content slurry will affect the working performance of decanter centrifuge.

In the final stage, the decanter centrifuge will separate out the solids smaller than 20um .Under the max 3000 G separation force, 95% solids will be removed. The discharged water is clean enough to reuse for the hydrovac excavation. This will save much cost of water. Meanwhile, the recycled solids can be used for building material according to the size. GN dewatering system is environment friendly, it get the good feedback from client to solve the sludge treatment problem , and recycle the water and building material to save resource.

We had built 11 sets dewatering system in North America, if you have demand ,welcome to contact us for more information.
