In most drilling project, no mater petroleum well drilling project, tunnel boring or mineral exploration drilling, most of them will use drilling mud to improve the drilling efficiency and also protect the rig machine. After sever recycled using, the drilling mud will include lots solids and it will make the mud lost property, so it is very necessary to remove out the inside solids and clean the mud for drilling work. GN solids control has focused on solids control equipment for more than 15 years. As begin we only provide equipment for oil gas industry to process the drill mud of oil gas. Along with the accumulation of technology, and also the requirement of our customer, we developed the mini Decanter centrifuge for mineral exploration mud process. Last week we delivery several units mineral exploration core drilling centrifuge for Europe client.

Compare with oil gas industry ,the diamond core drilling has small treating capacity and require small size equipment for field work. The system need to store up water for using anytime. Aim to this special requirement, GN developed this diamond core drilling mud unit. This unit is quit simple structure ,only one GN 9 inch centrifuge, feeding pump and a small bottom tank. This core equipment 9 inch centrifuge is our smallest centrifuge model with only 100 liter per hour treating capacity ,but for diamond core drilling ,this capacity is enough. The speed of this centrifuge can reach 4500 rpm. but we 3500 rpm is cost effective for mining slurry treatment.

As usually ,the slurry need pretreatment to reduce the solids content before feeding into Decanter centrifuge, but for diamond core, it is not necessary, we can directly feed. Because the solids density is higher much than liquid, and particle size is small. Our 9 inch centrifuge is very popular not only in Europe but also in Canada and also south Africa. If you have demand on our equipment, welcome to contact us.

Solids control is one of the very import link in the petroleum well drilling project, which is used solids control equipment to remove out the drill cutting from the mud, recycle mud and keep the property of mud. and the good mud can balance the pressure between inside and outside of well. and also protect the rig machine. Improve the rig drilling efficiency. Last week we delivered several sets Decanter centrifuge and screw pump for offshore drilling project.

In all solids control equipment ,Decanter centrifuge is the last stage for drilling mud processing. It can remove out the particle that smaller than 2o um, and clean the mud. GN have different models Decanter centrifuge according to the treating capacity ,GNLW452, GNLW363 are most used in the drilling project for mud treatment. For some big treating capacity, we will recommend 18 inch GNLW553 centrfiuge to customer. From the photo, we can see this centrfuge is a little difference with standard machine. It is used for offshore drilling, and has more strict requirement to lifting. As we all know, there is no forklift on offshore platform, so all equipment must weld the lifting eye. Sometimes end user will require the DNV lifting certificate. Centrifuge is one kind machine that utilize the rotate speed to generate the centrifuge force, and the different density solids and liquid will bear the different force, then the material will settle on different layer.

Except decanter centrifuge, We also provide centrifuge pump to customer. In drilling mud project, centrifuge pump is the most widely using pump. It is simple structure with stable quality. For the high density liquid transfer, centrifuge pump is the best optional for client.

GN solids control can provide the whole series solids control equipment, such as shale shaker, mud cleaner and also mud system , if your project have demand on our equipment ,please feel free to contact us.

GN Separation as one new brand of GN company, it main focus on the solids liquid separation industry. The separation equipment is not only limited the Decanter centrifuge ,shale shaker, we also design and manufacture the most efficiency separation and dewatering equipment to meet the market demanded.

Last week we delivered one screw press dewatering machine to units states customer. Screw press is one of the new machine of GN. We started to provide screw press to customer since 2019. Different with Decanter centrifuge, screw press is utilize the pressing force between move ring and fixed ring to squeeze the sludge to extrude the water included in sludge. Decanter centrifuge use the separation force generated under the high rotated speed, the different density material will bear the different separation force, and settle down on different layer. The solids will sink on the bottom and liquid above solids, through screw pusher to discharge the solids. Decanter centrifuge has the big treating capacity, the slurry sometimes do not need to mix flocculant. But the consumption of power is a litter higher, the discharged solids is not dry enough.

Screw press dewatering machine is lower power than Decanter centrifuge. It has the different model with treating capacity from 4kg/hour ~640kg/hour of dry solids weight. For customer, it has more optional to get the suitable model for their project. Low power is the most feature of this machine. such as the biggest model GNDL-404,which can process 133m3/hour and the total power is only 7.5kw. Simple structure made it easy to maintenance, actually only move ring and fixed ring need to replace after long time using. In most project, screw press dewatering machine need to run with chemical dosing unit, add flocculant to combine small particle into big one and then feed into screw press to dewater it.

GN can provide the customize separation and dewatering solution for your project, if you have demand on this ,welcome to contact us.

GN Solids Control has focused on separation and conveying area for more than 15 years. With the 15 years development ,we built our own brand GN solids control , and GN get the reputation from the market. Reliable quality and quick response help us win lots market and built long terms relationship with many top client in the world. We do not provide equipment, but also give the whole solution for the solids liquid separation and material conveying.

In our product line, except the normal pump for liquid transfer. We also developed GN solids vacuum pump this special type pump for high solids content material transfer and also for some solids power transfer. Different with normal pump, our vacuum pump was driven by high pressure. Utilize the air suction force and high pressure push force to suck and discharge material. All its component was driven by air include the pump valve. The normal type pump, such as centrifuge pump through the impeller to transfer liquid , but for high solids content material ,such as sludge ,drill cutting ,centrfiuge pump is useless. The solids vacuum can win this job.

last week, we delivered a vacuum pump to Asia customer, who use it to clean the waste pit. Using the pump to suck the sludge out from pit and transfer them away. In the vacuum pump , there is one venture structure, when high speed air through venture, the inside air of tank will be take away, and genera a vacuum space inside of tank. This the source of suction power. After the tank suck full sludge, through switch valve, the high speed air will directly input pump tank, the high pressure air will push the solids out of tank, and discharge them out. As usually, the pump can transfer most kind material with a little liquidity, and the most transfer distance can reach 500 meters . For some low density liquid, the distance even can reach 1000 meters.

This pump can solve most your  transfer problem of high solids content material. If your have demand on it, welcome to contact us.
