GN Drilling Mud Solids Control System For Coal Mining
GN is a equipment manufacture of solids control and waste treatment .At the begin of GN history , we main provide the equipment and service to the oil well drilling company ,such as the shale shaker ,mud cleaner ,shaker screens and also mud system etc .These equipment is main used to treat the drilling mud ,remove the solids from the mud. As long as the development of GN ,we not only serve oil well drilling , but also the other industrious which has the demand of solids-liquid separation. Last week we delivered one drilling mud solids control system for coal mining.
This solids control system has two application. One is clarify the drilling mud that generated in the coal drilling. This system include 2 units GN shale shaker, 1 set GN desander, 1 set GN desilter and also the centrifuge pump. The two sets shale shaker can remove the big particle size that bigger than 60 um. And the pump will transfer the material and feed into the desander . The desander is combination of hydrocycloe and shale shaker. After the desander treatment , will treated by the desilter ,desilter is used to remove more smaller particle. The drilling mud will be clean enough for reuse.
Except the solids control equipment ,this system also equipped the mud jet mixer. In the drilling program ,sometimes we need to adjust the mud density ,that need to mix some special material with water. This mud jet mixer include the mud hopper and centrifuge pump. This is a high efficiency unit with 45-340 m3/hour. This mud system consider the shipping delivery when make the design ,so the mud tank dimension can be load into container to transfer.
GN can provide the customized proposal for your project. That is our advantage to serve customer ,because different project has the different requirement. If your project has the demand to the solids-liquid separation , welcome to contact us , we will be pleased to share our experience and provide the technical support.
The Feature Of GN Decanter Centrifuge
As we all know the decanter centrifuge is one of the most popular equipment of GN. I would like to share the feature of GN decanter centrifuge.
First , decanter centrifuge is one kind machine that easy to wear . we select duplex stainless steel SS2304 and centrifugal casting are used to manufacturing rotating bowl, and shaft for big and small end cap. Duplex stainless steel is stronger and more resistant to abrasion and corrosion. This manufacturing process also avoid intergranular corrosion and incomplete release of stress. Screw blades are manufactured as a whole piece with CNC forming lathe, leading to high accuracy of the blades and higher solids discharge efficiency.
Second,optimized cone and pitch with BD plate to separate dewatering section and settling section, with deeper pond depth, longer dewatering section, dryer solids and clearer water. This also increase throughput speed. BD plate also helps solids discharge.
Third ,Less energy consumption is achieved with bigger pond depth, making decanter centrifuge use less energy. This also reduces turbidity flow of liquid to make separated water clearer, less wear on end blades which makes screw lastlonger.Dual cone angle is available for specific high solid concentration materials. The rotating bowl have two cone angles, which reduced discharge resistance and increase treatment capability while maintaining clarify of water and dryness of solids.
Third, All the rotating parts are made with high accuracy CNC machine. After that 3 step dynamic balancing is done. One is the balancing of rotating assembly at 1800RPM, balancing at real high speed and the balancing of whole machine to ensure stable operation of the decanter centrifuge at high speed.
Fourth,Part of centrifuge select the protected tiles and special design for easily operate and long lifetime .Discharge ports are specially made tungsten carbide with excellent anti-abrasion capability and less fragility;Easy opening mechanism is used so that one man can open the collection box cover for easy access of equipment; Hydraulic removing mechanism is built into main shaft, which reduced pulling force by 90% when removing main bearings, this helps to ensure the safety of the bearing and high precision parts; Both motors are placed in one end of the decanter centrifuges for more service space and spill of slurry to impact service life of motors;Oil lubrication is used to lower bearing temperature and clean bearings;
Fifth, select SKF premium bearing is used for longer service life, and the Real time monitoring of decanter centrifuge’s working condition for overload, bearing temperature, vibration, lubrication pressure, drive currents and screw torque and alarm .
All these feature make GN decanter centrifuge is one kind stable and reliable equipment ,If you want to know more , welcome to contact us.
Vertical Cutting Dryer For Environmental Project
After 13 years development GN has been the leader of solids control equipment. We had built three plant with more than 800000 square meters to manufacture different solids control and waste treatment equipment .Most GN equipment is used for drilling mud treatment to remove its solids and clarify the mud again for reuse . Actually GN equipment not only an be used for the oil gas industry ,but also good performance at some environment projects. Such as the waste water treatment. Last week we delivered vertical cutting dryer and screw conveyor to our customer .
The vertical cutting dryer is not used to treat the drilling cutting , which is used to dryer the solids phase that separated from shale shaker in the waste water treatment project. As usual , the solids discharged from shale shaker is very wet, it is inconvenient to transport, so we need to dryer it .GN vertical cutting dryer is big capacity machine with 50 tons /hour. And it is continuous work .After treatment the liquid content is only 8%-20% according to the different situation .It is a stable equipment ,the inside screen is processed with the special technology and anti -wear material. That can ensure the long lifetime . from the picture you can see that it install in a container ,that is because this project is a very cold area and it is also convenient for transport.
Except the cutting dryer , we also equipped the screw conveyor to feed material to cutting dryer ,solids will directly convey from shale shaker. This will help to improve the efficiency and reduce the cost of labor . The screw conveyor can increase the length according to the actual requirement , you just need to add the module section ,each section is 12 feet. Big capacity and stable.
GN has full experience in the solids-liquid separation ,not only in the oil gas industry ,but also environment project , if your project have demanded in these equipment , please contact us.
