How to Choose a Decanter Centrifuge for Barite Recovery

Barite, also called Baryte, or (BaSO4) is a mineral consistingof barium sulfate. As per statistic, 77% of worldbarite are used in oil and gas drilling as a weighted agent added to thedrilling fluid. It can give functions to suppress high formation pressures andprevent blowouts. Usually, for rig systems largerthan 1500HP, barite become a must adding agent.

Since barite is an expensive agent used fordrilling mud, to recover and reuse it becomes very important. And a best solution is a decanter centrifuge.


OGEM Solids Control is professional indesigning and manufacturing solids control and waste management decanter centrifuges, And OGEM has several optional decanter centrifuges for customers to choose from.

Based on characters of Barite, the diameter of Barite particle is around 7 micrometers. For recovery Barite needs a medium decanter centrifuge with rotation speed from 1600rpm to 2200rpm.

May you have more question about barite recovery or question about solids control & drilling waste management,please contact us.

Decanter centrifuge for drilling mud system and drilling waste management

Drilling fluid decanter centrifuge has different functions when it works in different

conditions. As for oil and energy field, we usually use decanter centrifuge for drilling mud

system and drilling waste management.

How does an oilfield decanter centrifuge work

Drilling mud decanter centrifuge is widely used in oil and gas drilling, chemical, foodstuff, pharmacy, mineral beneficiation, water treatment and many industries. You may think it is an ordinary machine. If you know of the usage of decanter centrifuge in oil drilling field, you can know what an important role it has.

Oilfield decanter centrifuge adopts centrifugal force to separate solid particles out of drilling fluids. The working principle seems to be easy. Actually, it is a complex process. The equipment is set with electronic box generating high-speed centrifugal force, which can speed up the setting velocity of particles in fluids and make the separation of particles with different sedimentation coefficient and buoyant density. The particle discharge is finished by the propeller. Under the action of the differential gear, the screw propeller and the drum form a certain speed difference. Settled particle on the inner wall of the roller is scrapped from the cylinder wall, down by helical blade into the small end of drum, and dehydration. Finally, the particles reach to the sand discharging nozzle, and was thrown into the drum. This drilling mud process from decanter centrifuge is finished.

Oilfield decanter centrifuge is applied to separate the particles or solids with different size and density in the different density and flow speed. The exact process is hard to imagine, while it is really useful. Due to the kind of oilfield solids control equipments, drilling fluids can be changed in an optimal condition, which is good to the drilling rigs and projects.



LXJ Series Decanter Centrifuge

LXJ series of Decanting Centrifuge separate the suspending liquid using the principle of centrifugal action, the suspending liquid is pushed into the rotor drum through the inlet pipe and the fluid hole of the spiral feeder.

Under the influence of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the nud export of the small end of the drum and excreted. But the liquid is excreted from the overflow hole of the large end. Such cycle is in order to achieve the purpose of continuous separation.

LXJ Decanter centrifuge

Mud decanter centrifuge is typical drilling mud process equipment. It is 4th phase solids control equipment. Usually it’s set behind AJC mud cleaner or desilter. Mainly separate 2~7 microns particles. The complet conveyor and bowl will be made of S.S to provide high resistance for drilling mud.

Furthermore, according to clients’ requirement the drilling mud centrifuge can be designed as VFD type. Permits easy adjustment of bowl, conveyor, and feed pump speeds for varying process conditions and provides torque overload protection.

Horizontal Spiral Sedimentation Centrifuge Working Principle

Horizontal spiral sedimentation centrifuge has become an impotant drilling fluid solids control equipment.Now high separation factor,large capacity and high reliability are the development trend of this type centrifuge.


Horizontal Spiral Sedimentation CentrifugeDrilling fluid decanter centrifuge could remove out the unwanted particals with size of minimum 2 microns from the drilling mud. The main motor and the assistant motor respectively drive the drum and differential to rotating by belt pulley on both of the large and small end. Inner the high-speed rotating drum there is a conveyor with screw blade, and the drum supported by the bearing house.

Drum is connected with the differential shell through the hollow shaft at the left bearing,the differential output shaft drive the screw conveyor and the drum to rotate homodromously, but the speed is different, the slip speed is 0.2% to 3% of drum rotation speed.

Drilling fluid is pumped into the drum through screw conveyor. Under the effect of the centrifugal force,a circle liquid pool was formed, the heavy solids phase particles settled to the inner surface of the drum. Due to the relative motion between the drum and spiral blade, solid sediment was pushed to the small end of the drum and discharged from the slag hole. While the clean drilling fluid discharge from the overflow hole set on the large end of the drum.

Qualified Decander centrifuge in Mud drilling system

Decanter centrifuge has rather wide range applications. For petroleum drilling, the decanter centrifuge function is purely drilling fluid. It is a part of solids control.

Decanter centrifuge in general

Decanter centrifuge is also called decanting centrifuge or centrifuge decanter. Different clients or users will have different names on it. Its working principle is to separate different size/density/weight object after centrifuge bowl rotating at high speed.

Heavy parts will be separated or flung out of processed goods. Usually, we have two phase and three phase centrifuge. Furthermore, we have middle speed centrifuge, high speed centrifuge, as well as VFD high speed decanter centrifuge.


As per different working condition, we can choose differential centrifuges. Since different speed centrifuge will realize different result and achieve different performance.

Petroleum drilling mud centrifuge

Petroleum drilling means oil well drilling. Gas drilling is similar with it. When we drill oil and gas well, the drilling mud will be purified and circulated. We call this mud process system as drilling mud solids control system, fluids purification/recirculation system, etc.

For petroleum drilling, there are 4 steps solids control process or we call it 5 phase’s fluid purification system. Anyhow, for petroleum drilling mud process, it is the final step. Usually separate 2~7 microns solids out of drilling fluid.


Furthermore, for petroleum drilling mud treatment we have both weighted and unweighted fluid. Then, centrifuge selection and configuration will be not same. The well drilling depth is relative with fluid treatment.

Petroleum mud centrifuge have 3 types in total. We can classify it as large capacity centrifuge, high speed centrifuge, and barite recirculation centrifuge. They have their own features and superiority. We can adopt them at certain occasion.

Since, different drilling condition and well depth sometimes we need configure or combine different types centrifuge together to get ideal performance and save petroleum drilling cost and get more benefit.


 Where to get petroleum drilling mud centrifuge?

Get high quality centrifuge for petroleum drilling mud process, we must know the treating capacity we need and drilling mud basic information. Such as if it is weighted or unweighted? Is it including barite or not?

As much information we know we can select ideal model centrifuges. Meanwhile, we can set VFD centrifuge for clients as option. The centrifuge will be adaptable for certain range specs drilling fluid.

Upon knowing on drilling mud, former mud equipments, such as mud cleaner or desilter separator we can match best centrifuge get optimal solution. Professional manufacturer and quality is core issue.

Please contact OGEM Equipment for more info on petroleum mud decanter centrifuges. Best price, high quality, and short delivery time.


Mud decander centrifuge in Solids control

Oil & Gas drilling high speed and VFD centrifuge

Oil well drilling and gas well drilling mainly mean the petroleum drilling and natural gas drilling. They both are vertical well drilling. And the depth from 2000m/6561ft to 9000m/29527ft. Let’s find similarity and difference between high speed centrifuge and VFD centrifuge.

High speed decanter centrifuge

We know, centrifuge in drilling fluid process is also called decanter centrifuge, decanting centrifuge or centrifuge decanter. There are many types centrifuge as per different division way.

If according to centrifuge speed there will be low speed centrifuge, middle speed centrifuge and high speed centrifuge, as well as the VFD high speed centrifuge.

High speed decanter centrifuge speed is up to 2800~3200rpm. And thanks to its speed, it can separate solids size 2~5 microns out of drilling fluid. Furthermore, high speed drilling fluid decanter centrifuge is widely used in barite recycling system.

High speed decanting centrifuge will have smaller bowl diameter to cater higher speed result. If the centrifuge bowl diameter is as long as 450mm or even longer, it can be only middle speed or low speed centrifuge.


Drilling mud VFD decanter centrifuge

VFD Decanter centrifuge means the variable frequency driven centrifuge. Almost users or players in oil and gas drilling will know that the VFD centrifuge is based on the high speed decanter centrifuge. So, we also call VFD centrifuge as VFD high speed centrifuge.

That means the VFD Centrifuge speed will be 0~3200rpm. And it will separate 2~5microns out of drilling mud same as common high speed centrifuge.

While, VFD to decanter centrifuge has two option. One is VFD for the centrifuge motors only; the other is VFD on both centrifuge motor and centrifuge feeding pump motor.

To VFD high speed centrifuge the control panel is rather important. Actually, the difference between VFD centrifuge and common high speed centrifuge is the control panel. We improve or make control panel realized VFD through one or some parts in the cabinet.

 Furthermore, if the VFD centrifuge is used in some special working condition with super high ambient temperature, we should consider match cabinet with cooling system together to ensure the safety without flame, etc.

The same features between high speed centrifuge and VFD centrifuge

As we said, both of them are high speed decanting centrifuge. They are widely used in oil and gas drilling. They both can get rid of 2~5microns particles. High speed centrifuge and VFD centrifuge will be set after drilling mud cleaner or the desilter

Both centrifuges will be fed by pumps from cleaner/desilter compartment to centrifuge feed inlet. They have almost the same design on structure, main parts, etc.

Drilling Mud Decanter Centrifuge

Difference between high speed and VFD centrifuge

Firstly, VFD decanter centrifuge is variable frequency or speed driven. It has more flexibility when operator or supervisor run centrifuge according to different mud property and actual working conditions.

Then, some VFD centrifuge will request feeding pumps are VFD as well.

Above information described general content on high speed centrifuge and VFD centrifuge.  If you need more info or you have any advice on it please let us know. We can discuss and improve together.


Professional Solid Control from China

Introduction of Solid Control

Solids control is a technique used for well drilling to provide prepared drilling fluids for drilling rigs. Drilling fluid maintenance cost, clean up, and disposal cost as well as the overall cost of boring can be reduced dramatically when proper solids control techniques are utilized.


These facts were recognized in the oil industry in the late 19th century when open earthen pits were used to separate the cuttings from the borehole. This was accomplished by a series of weirs and settling pits that allowed the solids to naturally settle out by using gravity.

The clean mud then flowed into a suction pit to be re-pumped down the hole. This was the first solids control technique ever used.

The next innovation in solids control came when the shale shaker was introduced in the early 1930s for the oil industry. The shale shakers were derived from technology used in the mining industry. The shale shaker remains today the primary piece of solids control equipment utilized in the industry.

Another machine borrowed from the mining industry in the 1930s was the cone classifier or hydrocyclone. The basic principle of this device involves the centripetal forces brought about by the high velocity of the drilling fluid spinning in the cone, forcing the larger and heavier solids to settle outward toward the cyclone wall and downward toward the underflow solids discharge. Together with the shale shaker, hydrocyclones have become an integral part of today’s solid control system.
