HDD Mud Dewatering Decanter Centrifuge for Sinopec Project

GN Company supplied one complete set of Decanter Centrifuge for Sinopec, which is used for their HDD mud treatment project. Now GN Company received great feedback from client, for the reliable performance and high quality of GN Decanter in actual work.

For HDD mud treatment project, generally the mud firstly comes to Vibrating Screen, where coarse particle would be separated out, and normally it is more than 100um. Then the mud would be fed into Decanter Centrifuge for separating out fine solids, especially for 2~5 um fine solids. Then the clean mud can be reused for HDD drilling project.

Decanter Centrifuge achieves solid liquid separation by Centrifugal force. When the mud is fed into Decanter Centrifuge, because of the difference of specific gravity of Solid and Liquid, there would become solid layer and liquid layer, with high rotation speed of Bowl. And the solid would be pushed out from the solids discharge outlet, and liquid phase would be discharge from the other side outlet.

Considering the high content of solids, there would be tungsten carbide tiles installed on the screw and discharge port, and it would greatly increase working life of decanter. And the tiles are replaceable.
In order to get better performance of removing fine solids from liquid by Decanter Centrifuge, generally there would be a Polymer Preparation Unit, which is used for dosing flocculent.

Besides supplying main dewatering equipment, GN Company can also supply Sludge Feeding Pump, Screw Conveyor, etc.

Welcome to contact GN Sales Manager, and they would offer One Stop Turnkey Solution for clients’ project.

GN Company Supplied Decanter Centrifuge for European Client

Client from Europe ordered one unit of Decanter Centrifuge for their refinery plant, used for oily wastewater dewatering.

Before this European client thought our Decanter’s bowl speed and centrifuge force are lower, when compared with European manufacturers. It is fact that Bowl Speed and g-force are important factor for dewatering capacity of Decanter. But that is not to say that dewatering capacity would increase as bowl speed increases, because capacity has limited value considering certain bowl size of decanter. Based on GN Company’s Engineers’ experience, 3400~3800 RPM is the optimal speed for this size of Decanter (bowl size 360mm). If the speed passes 3800rpm, the dewatering capacity would not increase. And at higher speed, the screw of decanter would suffer greater resistance to discharge sludge, and become more quickly to get abrasion. Therefor higher speed reduces the working hours/life of Decanter. Above all, GN Technical Team suggests it’s best to keep the Decanter within the range of its optimal speed.

GN Company’s Decanter Centrifuge’s speed can be adjustable through VFD in the control cabinet.
The presence of sediments in the liquid phase after treatment by GN Company Decanter is that Sediments in the liquid phase would not be recognized by eyes.

And GN Company Decanters’ both Vibration Protection and Bearing Temperature Protection are available and optional, and it can added based on clients’ requirement.

GN Company can also offer Main Motor Failure Alarm (including overload, current/torque, under-voltage, etc.), Back Motor Failure Alarm (including overload, current/torque, under-voltage, etc.), and Sludge Feeding Pump Failure Alarm.

GN Company Supplied Industrial Vibrating Screen for European Client

GN Company is a professional manufacturer of Solid Liquid Separation Equipment, including Decanter Centrifuge, Screw Press, and Industrial Vibrating Screen.

GN Industrial Vibrating Screen applies Q245R material, which is much better than Q235, quoted from other small factories, because it has better performance for suffering from corrosion, and not easy to get crack. And the screen’s whole body is stitched with rivets.

GN Industrial Vibrating Screen process technology applies of Once Annealing and Once Normalizing, which has obvious advantage of getting longer working hours. While only few manufacturers in China possesses this technology.

The screen is Polyurethane Mesh, which has longer working hours than normal steel mesh. And GN Company is capable to manufacture screen with size minimum from 0.1mm.

GN Company Industrial Vibrating Screen applies reputable European brand Motor instead of Chinese Brand motor. That motor has advantage of less maintenance and long working hours. And clients can easily find spare parts for the motor from local market, because the reputable brand motor has his distributors all over the world, which greatly save clients’ maintenance cost and time. While the other Vibrating Screens Manufacturers in China mainly use China brand motor.

GN Industrial Vibrating Screen applies protection level with IP66, which means the Screen can work in more terrible environment, while majority of manufactures apply the standard of IP54/55.

Another two big advantages of GN Screens are that, the tube beam of the whole machine adopts heat treatment process, which can prevent breakage. And the beam of the vibrating screen is also heat-treated to prevent breakage.

Welcome to contact GN Sales Managers, and they would offer detailed solution based on clients’ requirement.
