GN Shaker Screen is a subcompany of GN solids control which is API Q1 certified company.
GN Solids Control System for 1000HP Rig Machine
Solids control is one branch industry of drilling. In petroleum industry,oil well drilling is a complex project. As usual, the depth of well can reach 7000 meters. The drilling need mud to take out drill cutting from well and also balance the well pressure. GN has been in solids control equipment for more than 15years. We are the first China manufacture that got the API test report for all API code screen, and all our solids control equipment are comply with API standard. For now, we had funded our Houston branch to serve the America client , and Russia branch to serve the area that speak Russia. Last week we delivered 1 set solids control system to our European client. It will be matched with 1000HP rig machine.
The 1000 HP rig usually be used to rig the well less than 1000meters . Which have not too strict requirement to drill mud. As you can see from the photo, the system just include the shale shaker and decanter centrifuge. Shale shaker can remove out most big size particle, and if we use more higher API screen, the smallest particle size that we can remove is 44 um. That is very tiny particle. In this system we didn’t not add any desander and desilter, because the 1000 HP has a small require to the mud flow. If we want to get more cleaner mud, we just need to start the decanter centrifuge. The decanter centrifuge can separate out the particle between 20-40um.
In this system ,our engineer designed small size mud tank. Which is convenient for client to transport it into different job site and also easily to install. All the electrical control and electrical motor are comply with ATEX explosion proof standard to reach the European standard. Stable quality with competitive price, especially the design capacity and customized production are our advantage to serve will our client.

GN Mud Cleaner and Decanter Centrifuge for TBM Project
TBM is short of tunnel boring machine, which is one kind big equipment for the tunnel excavation. It is widely used in the subway tunnel ,and some other traffic project. When boring tunnel, the rig temperature will raise quick and also there will be lots of drilling cutting in the front of rig machine. So this machine need to use drilling mud to flush the drill bit for cooling. And also the mud will take out the drilling cutting out tunnel. As usually,the TBM project need large water, if we do not treat these mud. It will be series pollution and waste water.
Last week we delivered one desander and one GN decanter centrifuge for the TBM project. This desander was equipped bottom shaker. When the slurry feed into hydrocyclone, the liquid will be separated out under the separation force, and the solids will down to bottom shaker. The shaker could generate more than 7 G force with high frequency of vibration. The contained liquid and solids will be separate and follow into the mud tank.
As usually,the desander only can treat the particle bigger than 60 um, the TBM require the liquid as much clear as better. So we add the decanter centrifuge for further separation. GN 453 decanter centrifuge has be exported to many countries and served TBM project , which capacity is 60m3/hour. Decanter centrifuge is one kind equipment that utilize the G force that generated under the high rotated speed to reach the solids liquid separation. As we all know, the solids density is bigger than water. When the material bear big G force, the different density solids and liquid will separate layers, the bottom solids and top layer of liquid. Mud after decanter centrifuge , the solids content of discharged liquid will less than 5%, which is totally can be reuse for TBM.
GN has been in separation for more than 15 years. We have full experience and stable quality , if you you interest in our separation equipment , please contact us , we will be pleased to provide technical support.
GN Decanter Centrifuge for Mineral Salt Dewatering
With more then 15 years development ,GN Decanter centrifuge has developed several series for different application. At the beginning of GN history, we main served drilling company for the drilling mud treatment. Actually Decanter centrifuge has widely application in different country. GN T series is spec developed for the material dewatering.
As the client requirement, we made the experiment of mineral salt separation. This client want to got the solids salt as much dryer as possible. According to client the material parameter that our client provided, we mixed the same liquid with same solids content. From the photo we can see, the discharged white solids is dryer enough and it reached the requirement of our client. The discharged water is also clear enough for reusing.
GN C series decanter centrifuge have vanity model according to the treating capacity. They are 224,364,454，554. The treating capacity from 6m3/hour to 120m3/hour. Client can choose they model according to the quantity they will treat. 224 series is the most popular model with the mini size and low maintaining fees. Our Decanter centrifuge used the double stainless steel for centrifuge assemble to improve anti-wear and lifetime. In the solids discharged port, installed the tungsten carbon steel to prevent the abrasion from solids. Decanter centrifuge is one kind of high speed equipment, the rotated speed can reach 5000 rpm, the balance is the big challenge for manufacture, which required high accuracy. Every centrifuge assemble will pass 3 balance testing, include the dynamic balance. The high manufacture accuracy and strictly balance test can make sure the machine is the beast work state when delivery to our client.
The mineral salt separation is just one kind application. Decanter centrifuge can treat most material that need solids liquid separation. Through the centrifuge force generated under the high rotate speed, solids and liquid will bear different G force and finish the separation. If you have project need Decanter centrifuge ,welcome to contact us. We can make the separation experiment for you and share our experience.
