Separation equipment is one main business of GN, which include screw press dewatering machine , Decanter centrifuge ,disc centrifuge, shale shaker and also mud cleaner. As usually ,shale shaker and mud cleaner are most applicant on the solids control industry, such as oil well drilling, HDD, TBM. But decanter centrifuge not only for these project, but also for environment and waste water treatment. Disc centrifuge is for clarifying liquid or liquid-liquid separation. We received lots inquires from farm plant and some company main process manure . All these client request we give out solution to remove out the solids from manure fermentation as much as possible.

This manure fermentation liquid include about 10% solids , and particle between 3 to 70 um. As usually , it is not allowed to mix polymer such as flocculant. Because sometimes, they will use these liquid for irrigation. That makes project hard to remove out solid. For this situation , we recommend Decanter centrifuge as the first stage separation equipment . The separation G force of Decanter centrifuge can reach 3000G, it can separate out 90% particle bigger than 5um. Reduce the solids content between 2%-4%. The discharged solids moisture is about 50%, which seems very dry by naked eyes. The discharged liquid will feed into disc centrifuge for further treatment. The solids content has been reduce below 4%, which is very appropriate for disc to separate. The separation of disc centrifuge can reach 7000-8000G. even the tiny solids can be separated. However, disc centrifuge is good to clarifying liquid. The discharged solids is very wet, client need to dry it by other equipment.

GN separation equipment has been used in many environment industry. Our equipment get the good feedback from customer. especially in America market. We designed our own separation system for hydrovac slurry treatment. and sold it for more than 15 sets. If you have the similar project, welcome to contact us, we will be glad to share our experience.

GN solids vacuum pump is one of our most featured equipment. It was totally developed by GN. Currently, only 3 suppliers can provide this kind pump in all over the world. And GN is only the China company. Every year, we export more than 200 units pump to all over the world, and this quantity keep raising every year.

Different with normal pump, GN solids vacuum pump driven by pressure air provided by air compressor. And this pump can transfer dry solids that smaller than 75mm , and it is good at pump high solids control material such as drilling cutting ,sludge that the normal pump can not pump. The special application makes solids vacuum pump become one of the most popular equipment in market. Vacuum pump does not have complex structure, only one mud tank with several air control valve. Utilize the high pressure to make a vacuum space in mud tank inside, and then suck material into tank. Finally input air into mud tank to push the material to discharge out. This simple structure is also one the bigger advantage of this pump,more simple structure,more stable quality.
However, this pump still wold be some issue after long time using. Most times, these problem was caused by the dirty air. Even there is air filter inside the vacuum pump ,but some things dirty still may block air line of pump. Inside of control box, there is one 5-way valve ,which is used to Switch air flow direction to control material loading and uploading. When the pump do not work well, Most time it was cause by the blocking of 5 way valve. Client can disconnect the hose of top and bottom valve. And then connect air source, through high pressure to blow out the dirty inside of the valve and finish the valve cleaning. Finally, return the hose position and run the pump again.

Most times, we can solve the pump issue through cleaning 5 ways valve. If the cleaning is useless ,you can contact GN , and we will give out the suggestion to help you solve this issue.

In most drilling project, client made mud at job site. But there is also special mud company, they made mud and store them in big mud tank.When client need drilling mud ,they directly ship these mud to the drilling field. Usually ,mud station need big plant to lay huge mud tanks. These tank can store drilling mud , clean water, cement etc to made different type mud for drilling well using.

Most times, client will choose local tank manufacture to make these tank ,but some times, the material grade, the processing technical can not reach the customer requirement ,and this may cause the short life time of mud tank. other aspect ,mud station also need other kind solids control equipment to mixing mud and treat them , such as mud jet mixer, centrifuge pump, shear pump, Decanter centrifuge etc. The complex requirement to manufacture and equipment make there are less company can provide all things for a mud station. GN solids control is one of these company that have ability to provide a whole solution to customer to built mud station. From tank building to equipment assembly.

As we all know GN factor is located in China. To foreigner client, transport is a big issue and higher fees to ship these tank from China to their local. Consider all factors , such as manufacture time, processing technology, price , more longer time products, the cost of using actually is better than choosing a vendor who are short experience in these mud station project. Client trust GN and very satisfied to our service. From design to manufacture, and give out solution to transport, GN own a entire solution to help client built their mud station.

If you have project similar like mud station, such as waste water treatment, mining slurry tailer processing, river dredging project, HDD, TBM etc. Like these project need to treat the drilling mud , we will be pleased to provide the whole solution for your project.

GN Solids Control has served oil gas industry for more than 13 years. We mainly produce solids control equipment for drilling mud treatment and also the drill cutting process. Last month we just shipping one cutting dryer and screw conveyor to Africa to oilfield drilling field.

The drilling mud carry lots solids from well, after separation by the shale shaker. The clean mud will return back to mud system for drilling again. But the discharged drill cutting from shaker still very wet, which involved lots of drilling mud. As we all know drilling mud has lots high pollution chemical material, it can continuously influence the soil for many years, and drilling mud is very expensive. So we need to recycle these drilling mud as much as possible to reduce the pollution to environment and also save the cost of mud.

In this African project , screw conveyor can directly catch the discharged solids from shaker and transfer it into vertical cutting dryer. Inside dryer, there is cone shape basket with opening hole. Motor will drive the basket and generate separation force. Although solids and liquid both bear the separation force, but solids can not go through the opening hole, because the diameter is higher than the basket hole. The liquid mud will go through the basket and be collected. The primary is similar with dry function of washer. Dewatered solids will down to bottom of dryer and transport away for further process.

As usually, vertical cutting dryer is used for oil base drilling mud. Sometime client use it for water base mud, the solids may block the opening. So we do not suggest client use it for water base mud. After treatment , 95% percent of drill mud can be recovery. However the recovered liquid need to be further treated by decanter centrifuge to remove out bigger size particle, and then turn back to solids control system.

GN not only provide equipment, but also good at customize system, if you have the similar project, welcome to contact us.

Last week , a Latin America environment company focused purchasing several dewatering equipment for their project. The are screw press dewatering machine , Decanter centrifuge and chemical dosing unit. As one of the earliest separation company in China, we have more than 15 years experience on manufacture and equipment development. We exported equipment to more than 76 countries. Till now, GN own 3 manufacture foundation. Equipment application include oil gas, food beverage ,environment industrious. And environment sales is raising quickly. And we are also put more effort on the environment industry and serve our customer.

In these equipment we sold to customer. All these equipment are small treating capacity and mobile unit. Such as the decanter centrifuge. Client take it to the job site for some small treating capacity project, customer do not need to transport the waste into water plant. The decanter can process it well at job site. Which also equipped a bottom tank as buffer to convent customer to connect other equipment for further treatment, because the Decanter centrifuge is not good at separating the particle size smaller than 5um.

Client also purchased 1 unit 201 screw press dewatering machine and 1 unit 202 screw press, the 101 model equipped 1 500L/hour chemical dosing unit to feeding polymer. Screw press dewatering machine is good at separate out the material that solids content less than 5%, especially in some soft bio material. But if the particle is too small smaller than 10um. It is hard for machine to separate, we need to polymer to combine small particle to big one. The automatic chemical dosing unit can adjust and feeding medicine to material ,and help screw press to get better separation effect.

Our advantage is providing customized solution for customer, include select the optimal equipment model to solve problem and save money, and the solution must friendly to environment. If your have similar project demanded to solids-liquid separation, welcome to contact us.

Our Houston branch GN Solids America LLC just sold one dewatering system to local for construction slurry treatment. This system will be used to remove out solids from slurry and recycle water from sludge. The recycled waste will be used again as building material.

This system is not only applicant for construction slurry, but also hydrovac sludge treatment. It is a integrated system, which can sort out different size particle. The system include slurry catching hopper, mining shale shaker, mud cleaner, decanter centrifuge and also chemical dosing unit. The catching hopper has a steel filter in the surface, customer can directly dump waste into the hopper, the hopper will filter out big stone to avoid it damage separation equipment. slurry though the hopper drown into mining shake. It is a big shaker with large treating capacity, in this step. The grave and big size sand, these discharged can be used as building material. Discharged liquid will feed into mud cleaner. The mud cleaner include 10 inch hydrocyclone and 4 inch hydrocyclone. 10 in hydrocyclone is for removing particle size bigger than 60um, 4inch is to remove out bigger there 25um. Mud cleaner also mounted a bottom shaker with high mesh screen, it can separate the fine tiny.
In some project, the slurry after treating by mud cleaner is enough for reuse, but in some special project ,customer will require to get the liquid mucus cleaner much better. So we will feed liquid into Decanter centrifuge for finally separation. Different with shale shaker, it utilize centrifuge force generated in high rotated speed. Different density material under this high G force will be separate off. If the solids particle smaller than 5 um, flocculant will be feed through chemical dosing unit to combine tiny solids into bigger to help Decanter centrifuge to separate out these solids.
Actually, We had provided more than 15 systems in North America. Our system is very popular due to the good separation effect and high cost-effective. Every system is customized production according to client requirement. If you have demanded on our equipment, welcome to contact us.

Last week we shipped out 3 units GN vacuum pump and one screw press dewatering machine to our old client from environment industry. This customer almost purchase all dewatering equipment and pump from GN, The quality of our equipment satisfied client, they are a big fan to GN equipment.
GN Separation and transfer is one brand of ours. GN separation main focus on developing solids-liquid separate and also material transfer. Such our shale shaker, decanter centrifuge, disc centrifuge and screw press dewatering machine. according to the material situation, we can recommend suitable mode equipment to get the best treating result.

GN transfer equipment include centrifuge pump, centrifuge pump, screw conveyor and also GN solids vacuum pump. All these equipment is widely sued in the world. Such as centrifuge pump, it is 100% interchangeable with MISSION Magaum, it is one kind high efficiency and stable machine. GN Solids vacuum pump is our most feature product, it is different with normal pump, which can transfer dry solids size smaller than 75mm, and also have good performance to transfer high solids content material and high viscosity material. The transfer distance can reach 1000 meters. GN is the only China vendor that can manufacture this kind pump. In some material transfer such as oil sludge , sand ,drill cutting, GN vacuum pump is best optional.

Screw press dewatering machine normal to dewater the material that solids content less than 5%, which is especially good at process the organic material and soft material. The discharged solids is very dry, comparing with other kind dewatering machine, screw press is low power consumption and continuous work, easily operate and maintain. In some tiny solids material, we also recommend mix with flocculant to combine small particle into bigger one to help the machine get better dewatering effect.

Not only equipment, GN also can provide whole set separate solution, we are a manufacture with full experience technical department. If you have demanded, welcome to contact us.

In most waste management project, the waste material normal include vary kinds material, not only water, but also oil. This week we delivered one unit tricanter centrifuge to Africa client for the oil tank sludge treatment. Different with 2 phase Decanter centrifuge ,tricanter is 3 phase separator for liquid liquid solids separation. Which principle is same with decant centrifuge. Through the high rotating speed generate the high G force, the different undissolved material will bear different G force due to their density is different. and then the different material will be in different layer. The high density solids will settle down to the bottom of Decanter centrifuge. And the lighter solids will be on the up layer.

The most application of tricanter centrifuge is for oil water solids 3 phase separation. It equipped a centripetal pump inside the centrifuge rotating bowl, and it will pump the oil out of centrifuge. The solids will be push forward and discharged from small end of centrifuge, water discharged from big end. In this Africa project, waste material from the bottom of oil sludge tank. Which include large crud oil ,water and solids. Customer want to separate out the solids , water. And get the clean crude oil.
These waste was flushed thorough high pressure water. And through screw press to feed it into 3 phase decanter centrifuge. Under the more than 2000 G force, water oil and solids will be separated. In some project, we may add the shale shaker to treat the material first to remove out the big size particle, and reduce the solids content. Finally feed it into 3 phase decanter centrifuge. The low solids content will improve the treating capacity of centrifuge and also get good separation performance.

GN can provide the customized solution according to client requirement. shale shaker, Decanter centrifuge , screw press, chemical dosing unit, all these equipment may be used for client project. If you have demanded on these equipment, welcome to contact us, we will be pleased to provide technical support.

One our Canada client asked give out solution for the fermentation liquid separation. This fermentation is from animal manure, client want us remove out the solids as much as possible. It is different with other separation project ,because the solids content is small.

According to the data sheet of material, the solids content is less than 5%, and the most of the particle is smaller than 75um. As usually we will suggest client to add flocculant chemical to material to combine the tiny solids into bigger ,and then feed it into decanter centrifuge. But in this project, it is forbidden to add any chemical medicine. That is the biggest challenge in this project. One other challenge is the flow rate is 25m3/Hour.

In this kind project, 2 phase disc centrifuge is the best optional, but due to the huge treating capacity, we need to use several sets disc centrifuge as it treating capacity is only 8m3/Hour. That will increase the cost of equipment. After discuss with engineer, firstly we will feed the material into decanter centrifuge to reduce the solids content as much as possible, and then feed the liquid into disc centrifuge. The lower concentration liquid will improve the separation capacity of disc centrifuge.
In this project, client have no requirement to the dryness of discharged solids, so we do not need extra dryer facility for further treatment. because the discharged solids from disc centrifuge is very wet, it through the flush water to discharge solids. Different with disc centrifuge ,the discharged solid from Decanter centrifuge is very drey,but the liquid is not as clean as disc centrifuge.
GN Decanter treating capacity from 6 cube meter to 120 cube meter with vary model ,and the disc centrifuge capacity is between 1 cube meter to 25 cube meter. All these capacity is calculated when treat the clean water. We almost can satisfied all the project demanded. If you have demanded on these equipment, welcome to contact us .

Last week we delivered 1 set slurry processing system to customer for their TBM project. Tunnel boring is one very popular system to for the tunnel project , especially for some city subway building. In the boring program, it also need drilling mud to cool the rig machine and flush the solids ,and take it our from the tunnel. This will consume large water to mix the drilling mud. Drilling mud is very expensive and high pollution, it is very necessary to recycle it for reuse.

In this customer project, the job site is at downtown of city. The customer require our system to dryer the solids as much as possible to convenient transportation. And do not allow the liquid out of system and pollute the job site. This project is in winter, so we load all equipment into container to make sure the equipment will work under the best most adapt temperature. For this project, we recommend our GNLW764 Decanter centrifuge and chemical dosing unit .GNLW764 is the biggest Decanter model of GN, the diameter of centrifuge bowl is 760mm , and the length is 4 times of diameter. The wider bowl diameter means the Decanter can generate biggest G force under the same rotated speed. Actually, this model Decanter will generate 3000G force when the speed reach 2600 RPM. The discharged solids will be dry enough. The model Decanter capacity is 140m3/hour, we only need one unit to finish all the slurry processing job.

Except Decanter centrifuge, the automatic chemical dosing unit will mix flocculant and feed it into material. The tiny particle smaller than 5 um will combine into bigger particle by the flocculant influence. It will help decater centrifuge to separate out the solids and get more clarify mud. In the system , you may see the discharged solids from Decanter cent will be directly transfer away by screw conveyor. All the treating process need less labor work.

GN is good at provide the customized solution for drilling mud treatment, we have more than 15 years in this industry, if your project have demanded on our equipment, welcome to contact to us.
