GN Disc Centrifuge and Decanter Centrifuge Delivery to China Client
As we all know GN has been in solids control industry for more than 15 years, and we have 3 facility more than 40，000 sq meters. Our new factory will put into production in 2021,which 60% use the robot to improve productivity and get more stable quality. We do become a leader in solids control industry, not only in global market,but also in China domestic market. In solids control and separation industry, the core equipment is Decanter centrifuge and disc centrifuge. Last week we delivered one unit Decanter centrifuge and one unit disc centrifuge for China client.
Both Decanter centrifuge and disc centrifuge utilize the separated force to separate the solids and liquid. When the machine in the high rotate speed,which will generate separated force, the bigger density material will bear bigger G force, which will lead to the bigger density material settle down the bottom and reach the separation target. As usually, the speed of Decanter centrifuge is between 2500 to 4000rpm, and the max G force can reach 3000G. The max G force of disc centrifuge can be more than 1000G. So we can see. The disc centrifuge is more widely used to extract some chemical material, bio material, or oil-liquid separation etc. And we can get more clear liquid.
When we use decanter and disc centrifuge. Usually we suggest the solids content not over 10% before feeding into decanter centrifuge ,and solids content less than 3% when feed into disc centrifuge. Other with the solids will stuck machine and affect the separate effect. In most project,we will use Decanter first to remove out more solids, and the feed into the disc centrifuge to get more clean liquid.
Both decanter centrifuge and disc centrifuge can make the 3 phase separation, separate one kind solids and 2 kinds liquid in same time. Decanter centrifuge and disc centrifuge are equipment that have high requirement to machining precision, when we choose supplier , it is necessary to choose the reliable manufacture to make sure the sable quality and technical support.
3 Sets GN Dewatering System for European Client
After more than 15 years development, GN has accumulated much experience on the separation industry. At the primary of GN history, we main focus on providing equipment for solids control equipment for oil gas company. Our equipment main used to treat the drilling mud and built long terms cooperation with some top global energy company with good feedback from them. However, we are not limited on the solids control industry for now. We developed some models especially used for waste water treatment. Last week ,GN delivered 3 sets sludge dewatering system to European client.
As you know, Europe has the most strict requirement. After several times inspect to GN company, client finalized to use GN technical solution for the water treatment. From the picture you can see, the system combined with 2 parts. Part 1 is chemical dosing unit, which is used to feed flocculant to mix with slurry. The part 2 is a mud tank and installed with feeding pump and GN 224EP Decanter centrifuge.
Client require to remove out the particle smaller than 5 micron as much as possible ,it is hard to reach this target if we just take mechanical separation, so the flocculant iso necessary to combine the tiny solids into big to easy separate by Decanter centrifuge. The chemical dosing unit can feed medicine to 3 Decanter in same time. And it can be controlled separately.
We are required by client to design the mud tank as small as we can. GN224 series Decanter is the smallest model with 9 inch diameter of centrifugal bowl. The special design of cone angel will keep the discharged solids dryer enough. Small size decanter will allow us to use a tiny mud tank to install it. All the system is full automatic and continuous work, which will save much cost of labor for client. The stable quality will make sure the less cost of maintenance. Simply operation, stable quality, automatic are the features of GN equipment. If you have demand,please feel free to contact us.
GN 764 Decanter Centrifuge for Coal Washing
As we all know Thermal power plant ,coal washing and coal mineral these industry always treat large coal, and wash the coal before use it. The cola after washing is convenient to use and improve the thermal efficiency. But it also generate large waste water, which will pollute the environment, GN Decanter centrifuge is specially developed for the waste water treatment.
In the coal washing process , which will add various type additive, these mixture always heavy noxious, and include large of fine coal in the waste water. How to reduce the pollution ,recycle the coal and clean water for reusing ? That is a big problem for every company. Decanter centrifuge is one of the best solution. First, it is one kind continuous working machine and automatic, that can satisfied the big treating requirement. Second, decanter centrifuge can separate out the particle smaller than 5um, after we mixed with flocculant, the tiny particle less than 5um also can be removed. Third ,the discharged water from decanter centrifuge can be directly reuse to the coal washing system, it do no need to any further treating. The recycled coal and water will save much money for company.
GN 764 Decanter centrifuge is the biggest model of us. To be honest ,this model doesn’t suitable other industry except mineral industry. As we all know, mineral always generated large slurry, the 764 big treating capacity is his biggest feature not only for coal washing ,but also for all different mineral slurry separation. It centrifuge bowl diameter is 760mm and the length is 4 times of diameter. The more longer bowl length means the slurry will stay more longer inside decanter ,and get more better separate effect. The centrifuge bowl is the main component of the decanter, it directly affect the stability. Every GN centrifuge bowl must pass 3 times balance testing to make sure reach the best performance.
If your project have demand in the big treating capacity decanter, welcome to contact us.
