APLW Drilling Mud Decanter Centrifuge Dynamic Balance

Treatment of Drilling Mud with APLW Drilling Mud Decanter Centrifuge

APLW Series decanter centrifugeTreatment Of Drilling Mud, Emulsions and Fluids With Decanter Centrifuges. Modern drilling emulsions form a closed circuit from which no solids emerge. Drilling fluids after processed by APLW centrifuge, the cuttings or solids between 2-7 microns will be separated out. 

The screw conveyor and bowl adopt the most advanced, reliable and convenient wear-resistant treatment technology and structure in China. All bearings adopt original imported NSK/SKF bearings. The electric control box is made of electrical elements from famous brands such as Siemens and Schneider.

AP decanter differential speed automatic control technology can automatically adjust the screw conveyor’s differential speed, to prevent overload and blockage. The complete machine is equipped with a bearing temperature sensor and vibration sensor and is provided with alarms for main motor overload, differential over-torque, low differential speed, etc. Meanwhile, its supporting frequency conversion (flameproof) control cabinet can realize automatic start and stop with one key.

Decanter centrifuge is also referred to as centrifuge decanter, decanting centrifuge.

In oil and gas drilling, we call then solids control centrifuge or drilling fluids centrifuges. Drilling mud is pumped into centrifuge by screw pump or submersible slurry pump. The treating capacity is from 40-65m³/h. Higher speed centrifuge process less drilling fluids or produce fewer particles. However, higher speed centrifuge separates finer solids out of drilling mud. Centrifuge mud source is in the desilter tank/compartment. 

Why do we call centrifuge the 4th solids control equipment or the 5th cleaning equipment?

Because it's behind desilter cone or mud cleaner. The middle-speed centrifuge is usually fixed frequency and get rid of 5-7microns cuttings. While the high-speed one is usually VFD and separate 2-5 microns cuttings out of the liquid. 

The material of decanter centrifuge is stainless steel. The minimum grade is S.S304, and then S.S316, S.S316L, Duplex 2205. The screw impeller can be welded or coated with tungsten carbide for better anti-corrosive performance. This will help us to get longer service life and save time to maintain or repair

Besides cuttings separation in drilling mud, the centrifuge is also used to recycle some barite. And decanter centrifuge is widely used in waste management, oil sludge treatment more and more.

Your Advantages In Processing Drilling Mud and Emulsions:

• Reduction in disposal costs
• Reduction in the quantity of sludge in the closed system
• Cost-saving of up to 60% for maintenance and upkeep
• Reduction in wear, especially on the slurry pump and drill bit
• Extended sludge service life

The decanter centrifuge bowl size is ranged from 450x1000mm to 530x1320mm. Different size drums will produce a different flow rate. Of course, the speed is not the same on all centrifuges.

Worldwide, a hundred decanters are already in use in the drilling slurry industry. Aipu solids control has a broad range of experience and numerous references that offer you decisive advantages:

• Decanters specially adapted to the drilling slurry, with special wear protection
• Production of the decanters exclusively in Germany, with high-quality materials and trained specialists
• Many years of experience and relevant specialist knowledge in the use of decanters for processing drilling slurry, drilling emulsions and drilling muds
• Inexpensive, worldwide aftersales service and a comparatively low amount of maintenance work
• Personal support, on-site service and project planning individually tailored to your requirements
