decanter centrifuge

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.

Welcome to contact GN Sales Managers, and they would offer One Stop Turnkey Solution based on clients’ requirement.

Recently GN Company has completed production of a batch of Screw Conveyors and Centrifugal Pumps, and plan to arrange shipment to Russian Client soon.

Company is a professional manufacturer of Separation & Conveying Equipment for 13 years, and our Equipment includes as follow,
2/3 Phase Decanter Centrifuge
2/3 Phase Disc Separator
Oil Water Separator
Screw Conveyor
Screw Pump
Centrifugal Pump
Sludge Solids Transfer Pump, etc.

For Screw Conveyor,
GN Company now has two kinds of models, including U-Type Screw Conveyor and Tube-Type Screw Conveyor.
U-Type Screw Conveyor can be used for moving wet or dry material, either horizontally or vertically. Tube-Type Screw Conveyor can be used for conveying powder and granular material on incline or vertically (normally the feeding material is less than 5mm).

For Centrifugal Pump,
The Pump can be used to transfer mud slurry, wastewater (the solids less than 2mm) in Oil & Gas Drilling, Environmental Waste, Mining, Construction, etc. The Pump Material can be customize, to make it suitable for working in high volume, high temperature, and high corrosion situation.
And GN Pump is 100% interchangeable with International Reputable Brand.

Besides supplying single equipment, GN Company takes more advantages of delivering customized One Stop Turnkey Solution for your project, including Design & Manufacturing. And GN Company Technical Team can design & manufacture the whole system in Containerization or Skid, which is more safety, and easier for transportation by truck, and movable around different job sites.

GN Company delivered one set of Polymer Dosing System for client from Africa, which is used to help Centrifuge to get better performance during dewatering. Because during sludge dewatering process, the ultrafine solids (less than 2um) cannot be separated by Centrifuge directly.

The Polymer Dosing System is help to gather the fine solids together, and form flocculent, which is easier to be by separated by Decanter.

GN Company is a professional manufacturer of Decanter Centrifuge, with capability of manufacturing Centrifuge with bowl diameter of 220mm~760mm, capacity of from 1~2m3/hour to 120m3/hour. GN Technical Team is a very professional team, with experience of R&D for more than 10 years.

Here are introduction about Constant Torque self-adaptation Function for GN Decanter Centrifuge.

When concentration changes, the current of back motor (for driving screw) would fluctuate accordingly.

1. When the monitored current value of back motor exceeds set value, the differential speed of centrifuge is too low, the control-programming program automatically controls the back motor working current to decrease to the preset value, and increases the differential speed of centrifuge.

2. When the monitored current value of back motor returns to normal setting value range, the control-programming program automatically controls the auxiliary motor working current to return to the preset value, and the differential speed of centrifuge returns to the normal.

3. When the monitored current value of back motor is low to the set value, the differential speed of centrifuge is too high, the control-programming program automatically controls working current of back motor to rise to the preset value, and reduces the differential speed of centrifuge.

4. Constant Torque self-adaptation Function can ensure the uniform of dry humidity of sludge (discharged from Centrifuge), and avoid the plugging problem caused by concentration change of feeding sludge, which provides reliable guarantee for the normal and stable operation of centrifuge.
