GN has focused on on separation industry for more than 15 years. At beginning, we main served the oil gas industry to help our client treating the drilling mud, such as the shale shaker, mud cleaner, decanter centrifuge. With the company development and the technology accumulation, we have developed many different kinds separation machine for different application. Such as the screw press dewatering machine. Last week we delivered our 201 models screw press to our customer from Peru.

Screw press dewatering machine is different decanter centrifuge. Decanter centrifuge utilizes the centrifuge force that generated under the high rotate speed, the solids and liquid will be separated into different layers. Screw press is through press material to make the solids dryer and get the clean liquid, the energy consumption is more lower. As usual, it can not treat the material with hard solids inside. And also need to mix with chemical to combine the solids into flocccule and then the machine can separate well. The treatment capacity is depended on the solids content of material. The more higher solids content ,the smaller treatment capacity. As usually, the max solids content should no more than 5%, otherwise the material should be treated by shale shaker to reduce solids content.

Low power consumption is the the biggest advantage compared with other equipment. For example the biggest model GNDL-404 with 52m3/hour capacity, which power is only 6 kw, the same capacity decanter centrifuge is 37-45kw. This feature makes it very popular in different industry, especially in the food industry, waste water treatment etc. And also for some special industry, we can use different material to satisfied the industry standard. For example ,we choose stainless SS316 for food industry.
GN has lot of experience in solids-liquid separation,not only the equipment, but also some customized system for special project, we provide the technical support by free. If your project have demand in our equipment, welcome to contact us.

With the human development, the human activity really affect a lot to environment, and lead to the big pollution to ecosystem. And we also customer a big large of resource and generate waste. GN has committed on the waste treatment for many years. We are happy for our work to provide equipment to treat waste and make it to reuse again. For most waste material, the first step of treating is separation. We need to sort out the waste into different types. Such as the sludge, which include solids and water, GN decanter centrifuge is good optional for these kind sludge treatment. Last week, we delivered the Vacuum pump and decanter centrifuge for environmental project to treat the sludge.

These waste from the water tank in water plant. The bottom of water tank will deposit the solids, it is will block pipe and dirty the water. Client choose GN 224 decanter centrifuge to treat this sludge. As normal, the decanter centrifuge is good performance to treat the material that solids content less than 20%, and after treating solids content will no more than 5%. GN224 decanter centrifuge is the smallest capacity decanter with 100 liter/min. It cover a small area and convenient to transfer in different project, and actually the bowl diameter is only 220mm and 890mm length. The waste discharged from the decanter is clean enough to reuse, and the solids will be transport away by solids vacuum pump. In this project, we provide 5m3/hour solids vacuum pump , it is suitable to match with 224 decanter. The vacuum pump is drive by air, and you can see it is also small and equipped with wheel. The vacuum pump transfer distance can reach 500 meters. It can reach most requirement of project.

GN has strict quality control and full experience for the separation project, and we have branch in Houston ,If your project have need in these project , welcome to contact us.

GN committed to manufacture the most reliable quality with quick after sale service. We had focus on the solids-liquid separation industry for more than 15 years. At the beginning of GN, we main serve the drilling company to treat the drilling mud. We never stopped to develop the new technology and update our equipment .Today I would like to share GN 223 Decanter centrifuge.

The decanter centrifuge is widely application in different industry. GN has the various model decanter with the different treating capacity. According to the bowl diameter, we have 220mm bowl decanter,350mm, 450mm,550mm, and 760mm. The more bigger bowl diameter require more higher process technology. Big diameter bowl centrifuge most used on some the high treating capacity project. Less company provide the small capacity decanter, actually many client require the mini centrifuge for some testing project.

GN 223 decanter centrifuge is the smallest decanter centrifuge with 220 mm diameter bowl, which bowl length is 3 times of diameter. It is small electric consume ,and the treating capacity is 100L/min. The max speed is 4500rpm with 2492 G force. It is very suitable for the separation of mining explore material. Little quantity and easy to transport to different job site. The centrifuge bowl material is SS304, which is more strength and anti-wear. And centrifuge bowl assembly main include the bowl ,screw, gearbox, belt pulley and tensioning wheel . It is simple structure with high assembly precision. And also centrifuge assembly is the most important part of decanter.
Our decanter have two types of drive, one is fixed speed and the VFD. VFD is higher cost and but it more widely application, because we can adjust the rotated speed according to our requirement. Foe now ,GN223 decanter centrifuge has exported more than 60 countries and get the good feedback from out customer. If you have demanded on the decanter centrifuge ,please feel free to let us know.

Solids control equipment is the core business of GN, and we have committed to server drilling mud company for more than 15 years. Not only the equipment ,but also some customized system, such the mud system, drilling cutting treatment system, oil sludge treatment system etc. We accumulate large experience of the drilling mud treatment as we worked on different situation drilling project.

Last week, we just finish the produce and commissioning the drilling mud station for our South Americas client. This mud station is consist of 14 Pcs 500bbl vertical mud tank and 1 Pcs 500bbl mud mixer tank. It is a complex mud station, which can store the diesel , clean water and some solids of mud additive. One set 75kw centrifuge that can suck the mud from every tank.

As we all know the drilling mud is very important for the oil well drilling, which can protect the rig machine ,lubricate the drills ,balance the well pressure and carry out the drill cutting from the oil. The mud station is one of the most important of the drilling system to provide the high quality mud. So the mud station must be reliable. 500bbl is a big volume and the vertical tank cost is higher than the cuboid tank. Considered the transportation and also the job site area ,GN technical team choose the vertical tank even the cost is more higher. The client is urgent and require 40 days to finish all the manufacture, it seems impossible, after the discussion, the whole manufacture department support this project and we finally completed all the manufacture with high quality. From the picture you can see, every tank is huge, which required the high welding technology and machining precision , the success of this project is benefit by our full experience of some the big mud system.
Our team is excellent with the attitude that supply the best solution to save the problem for customer. If you have demanded on the solids control equipment, welcome to contact us.

With the 15 years development, GN has got his reputation from the market because the good quality and after sale service. As we all know, at the beginning of GN found , GN main serve the petroleum industry to help drilling equipment treat the drilling mud. GN grow up quickly and gathered the full experience as we provide more and more various projects. The rich experience and the company culture that provide the best solution to client are our best treasure.

Last week we delivery Mini solids-liquid separation system fro European client. European has the most strictly require to the quality, but the client finally select us the partner.This system is a full customized , which specially designed for client project. Include the color, capacity and electrical system. This system include the GN752 shale shaker and GN223 decanter centrifuge. Both the two equipment are the smallest capacity model of GN. GN 752 shaker is a mini shaker with only 45 cubic meter treating capacity. The vibration of shaker is Italy OLI, which is a famous motor brand with reliable quality. Actually GN always choose the famous brand as the supplier. Such as the SKF bearing, SEMENSE electrical component etc. The big size solids in the material will be remove out by the shaker, and then the fluid will get into the below tank. The feeding pump will transfer the fluid into the decanter centrifuge, which can separate out the tiny solids under the high G force generated by the high rotated speed. After the system treated, we can get the clarifying liquid and dry solids. The liquid is enough to recycle into the drilling mud system for reusing.

This system is environmental friendly and economy with low power. It is continuous working system with high automatic. If you also the similar project to separate the liquid and solids, welcome to contact us. Our USA branch and China HQ both will be happy to share the experience and quote.
