GN Solids Control have more than 13 years manufacture and design experience in Decanter centrifuge. As one of the earliest enterprise of solids control company in China. We exported our equipment to 76 countries all over the world, and built long term cooperate relationship with lots of customer. At the beginning of GN, we main serve oil gas industry to process the drilling mud, and we deigned our own Decanter centrifuge for these drilling mud treat .So what we do best of Decanter is the application on drilling mud treatment.

In drilling mud treatment, GNLW-363VFD is the most popular model. The centrifuge bowl is 14 inch with 45 m3/hour treating capacity when material is water. Along with the solids content raising of material ,the treating capacity will be smaller. The typical capacity is 30m3/hour in work field. This treating capacity almost can satisfied most of the drilling project. Since Decanter centrifuge only be used to separate the particle size smaller than 20um. Only when material include overmuch tiny particle, we run Decanter centrifuge to treat drilling mud.
The moisture of discharged solids is adjustable through change the centrifuge rotating speed. Higher speed would get dryer solids and more clarify liquid. As generally , the solid dryness in following picture is enough for most project. If you want to get more dryer, keep raising speed. High speed and high solids content will speed up the wear of equipment. So choose the adapted speed is helpful to extend equipment lifetime.

GN363 decanter centrifuge also has the fixed speed version. Our engineer will setup the speed in our factory before delivery. Compare with VFD, the application is limited due to the speed is non-adjustable. To some single application or some material with changeless solids content, fixed decanter centrifuge is more economic. Actually, many clients choose this fixed speed decanter for their drilling mud treatment.
Our decanter centrifuge is comply with API standard, if you have demanded on drilling mud treatment, welcome to contact us.

Decanter centrifuge is the most widely used solids-liquid separation equipment in vary industries. GN Solids control has more than 13 years experience in manufacture and designing of Decanter centrifuge. We exported our Decanter centrifuge to 76 countries of all over the world, and we get the good reputation from our customer.

Last week client sent us some chemical sample to test the decanter cent, and to see if our centrifuge is suitable to their manganesesulfate solution dewatering project. In this kind chemical project, most client will require the discharged solids as dry as possible. So we select our T series Decanter centrifuge for this experiment. GNLW-224ET is one mini centrifuge, the treating capacity is 6 m3/hour, and centrifuge bowl is only 9inch, it is very popular in some mining explore project, to use it process the drilling slurry.

In this experiment, our engineer modulate the saturated solution till we can see the crystal of manganoussulfate. Stop add the solids when the solids content reach 15% the totally same status with customer project. Connect the screw pump, and trans the liquid into Decanter centrifuge. To get the most dry solids, we directly adjust the centrifuge speed into 4500 rpm with 2500G force. Under this work situation, the moisture of discharged solids is 2.58%, and the solids content of discharged liquid is 0.3% in volume rate. This separation result reached client requirement, and more better than they expected. After experiment , our engineer recommend the suitable mode of Decanter centrifuge to client according to the treating capacity.
Decanter centrifuge is the best solution for chemical separation. But we need to select special material to make the centrifuge when separate some corrosive material such as sodiumchloride. The chloridion will corrosive centrifuge bowl and scroll. So it is very important to check with our engineer when you use GN Decanter centrifuge to process uncommon material. Not only decanter centrifuge, but we also can provide disc centrifuge ,screw press etc. If you have demanded on our equipment, welcome to contact us.

8 sets screw conveyor and 8 sets screw pump are ready to ship to Africa, which will be used for the waste transfer in oilfield. Such as the drill cutting ad some other waste material. Conveying equipment is one of main business of GN. Mostly we sold out conveyor equipment with our separation facility, such as Decanter centrifuge, shale shaker.

Screw pump is also one kind dosing pump. Mostly, we use it as feeding pump to transfer slurry into Decanter centrifuge since the flow rate is stable. The electrical control can adjust the flow thorough change the rotated speed of screw pump. GN cooperate with NETCH one German pump brand. After installing motor and connect with centrifuge control box, we combine the screw pump and decanter centrifuge into a system. All will be automatic controlled on the central control box. The operation is very easy and stable. GN screw pump treating capacity from 10m3- 90m3 with vary model.

Screw conveyor is the most application transfer machine in waste management. Through the screw rotating to push the solids go ahead, and transfer it into the target place. The screw is installed inside of conveyor box, there is no leaking when transfer it. GN screw conveyor is module design, one entire conveyor is consist with several standard section, one section length is 12 ft. The user can decide how many section then need according to the actual project, and combine these section into one machine to fit the transfer distance. When client need to transfer material from lower place, client just need to adjust the support frame under the conveyor to change the transfer angle. It is very convenient because the support leg height is adjustable.
Compare with other kind transfer equipment, screw conveyor running is stable with high transfer capacity. And it cover a small area to save space. Screw conveyor also can customized manufacture according to your project. Actually we sold several sets customized conveyor to Mexico. If you have the demanded on these equipment, welcome to contact us.

Last week we delivered 2 units solids vacuum pump to Europe. This year, we had export more than 100 units pump to all over the world. And the vacuum pump get the good feedback from customer.

Solids vacuum pump is GN feature product. Specially designed by GN and used for solids transfer. Different with normal pump, it is driven by high pressure air, which can transfer not only liquid but also the high solids content material. Such as the drilling cutting ,oil sludge, sand etc. This solids pump has long transfer distance, which can almost reach 1000 meters. But the suction height is less than 12 meters when the material is water. Because is utilize the vacuum to generate the suck force, so the suck force will less than than atmospheric pressure, which lead the pump is not good at suction. But the discharge height can reach 20 meters.
Solids vacuum pump is only one kind pump that can transfer the dry solids. GN Solids Control is only manufacture that can manufacture this kind pump. The long transfer distance and transfer solids make it can be used in many industry. Such as the river dredging, sludge transfer, transfer the manure in farm etc. Improve the work efficient and reduce the labor work. This pump almost no stuck due to the special design , and 100 % air driven means it is total explosion proof.

As for now, we have 3 model with different transfer capacity. 40B, 20B, and 10B. The corresponding capacity is 40m3/hour, 20m3/hour, 10m3/hour. This designed capacity is when the material be water. The actual capacity will be vary when material viscosity, density, and altitude.
we can foresee that solids vacuum pump as a new type pump, the market demanded will have a big growth. We are also searching the potential agency to cooperate to push this pump to their local market. If you are interest, welcome to contact us.

Last week, we received the using report of Decanter centrifuge from our Latin America customer. Client is very satisfied with GN equipment and shared some photos of job site. To be honest ,the transnational purchase is very hard, which require supplier supplier full experience to make sure we provide the suitable equipment to satisfied client using, and also control the cost. GN has more than 15 years experience in the solids control equipment manufacture. After we get client project information, quickly recommend our 363 model to client.

GN has many long term partners in Latin America ,but this client know less about GN products. After we shared some project case in America, client decide to place the order from GN. 40 days manufacture and 30 days shipping from China. Client received the machine, and then we had a online training to customer about the operating, actually GN Decanter operator is very simple, all setup can be done through touch screen. At the first time using, client begin to love GN Decanter centrifuge . The good performance and easily operation. After that, they placed an other purchase order about Decanter centrifuge, and it is on manufacturing now. Client is also interested in the other solids control equipment about shaker, mud cleaner, mud agitator etc.

GNLW363 Decanter centrifuge is especially suitable to drilling mud treatment. it's centrifuge bowl diameter is 360mm with 1080 length. The design capacity is 45 cube meter per hour, and the actual is 30 cube meter. This treating capacity can satisfied most drilling project. As we all know, the Decanter centrifuge is used to separate the liquid after mud cleaner to remove out the particle size smaller than 20um. So sometimes, it would be run when the mud contain too much tiny solids. The 30 cube meter per hour is most economic model for client. We do have bigger capacity Decanter centrifuge ,such as 553 Decanter ,764 Decanter. The capacity is more than 100 cube meter per hour.
GN has full experience on the solids control equipment, if your project have demanded on these kind equipment, welcome to contact us.
