What are the main types of drilling mud centrifuges?

The main types of drilling mud centrifuges are as follows:

1, Decanter Centrifuge:

Decanter centrifuges, also known as horizontal centrifuges or scroll centrifuges, are the most commonly used type in drilling operations. They utilize a horizontal rotating bowl and a helical screw conveyor inside the bowl. The drilling mud is fed into the bowl, where centrifugal force separates the solids from the liquid. The screw conveyor then moves the solids toward the discharge ports, while the clarified liquid overflows and is collected separately.

2, Vertical Cuttings Dryer:

Vertical cuttings dryers are specialized centrifuges designed specifically for the treatment of drilling cuttings. They are typically used in combination with shale shakers and are primarily focused on drying and recovering drilling fluids from the cuttings. The cuttings are fed into a vertical rotating drum, and the centrifugal force generated within the drum separates the liquid from the solids. The liquid is discharged, while the dried cuttings are expelled from the dryer.

3, High-Speed Centrifuge:

High-speed centrifuges are capable of achieving higher rotational speeds, resulting in greater centrifugal force. These centrifuges are particularly effective in separating finer solids and achieving a higher degree of solids control. They are often used in applications where drilling mud requires fine filtration and clarification.

4, Low-Speed Centrifuge:

Low-speed centrifuges operate at lower rotational speeds compared to high-speed centrifuges. They are primarily used for dewatering and thickening drilling mud, where the focus is on separating larger particles and achieving higher solids content in the discharged solids.

5, Basket Centrifuge:

Basket centrifuges, also known as vertical or conical centrifuges, consist of a vertical rotating basket with perforated walls. The drilling mud is fed into the basket, and the centrifugal force separates the solids from the liquid. The solids accumulate on the inner surface of the basket, while the clarified liquid overflows and is collected separately.

6, Pusher Centrifuge:

Pusher centrifuges are continuous-feed centrifuges that operate with a pusher mechanism. They are typically used for large-scale solids control and are known for their high capacity and continuous operation. The drilling mud is continuously fed into the centrifuge, and the pusher mechanism moves the solids through the machine, separating them from the liquid.

Each type of drilling mud centrifuge has its own advantages and is suitable for specific applications and operational requirements. The selection of the centrifuge type depends on factors such as the nature of the solids, desired separation efficiency, processing capacity, and the overall solids control objectives of the drilling operation.

Model Selection Guide of Decanter Centrifuge

Many people can easily know how to choose a decanter centrifuge, but it is a little difficult for them to select a suitable model of centrifuge. Here is a simple method to judge a proper model for you.

First, the model of a decanter centrifuge represents the following meanings: For example, LW450*842, a model of decanter centrifuge, among which L means Luoxuan in Chinese Pinyin, W means Woshi in Chinese Pinyin, 450 means the bowl diameter of decanter centrifuge, and 842 means the bowl length of decanter centrifuge.

A suitable model of decanter centrifuge can not only solve production problems and improve work efficiency, but also save production cost and reduce business risks. Several main factors that determine the centrifuge model are as follows:

Speed of decanter centrifuge: The speed of a common decanter centrifuge is more than 2000RPM. For some materials hard to separate, a higher speed is required. The higher the speed is, the higher the separation factor of centrifuge, the better the separation effect.
Material of decanter centrifuge: PH value of materials to be treated determines the bowl material of decanter centrifuge. Different materials have diverse physical and chemical indexes in their abrasion and corrosion resistances. Overseas decanter centrifuges are generally made of 316L or duplex stainless steel, with wear parts made of ceramic materials.
Differential control of decanter centrifuge: Different differentials have different control accuracies, service lives and maintenance costs. The higher its differential accuracy is, the better its adaptation to materials is. So it is advisable to select equipment with a high differential accuracy.
Length-diameter ratio: The bigger the length-diameter ratio of decanter centrifuge is, the higher the handling capacity is, the lower the moisture content is.
Control system: At present, almost all of equipment manufacturers at home and abroad have achieved a full automatic control over the equipment.
Installed power: As for a control over energy consumption, generally speaking, domestic equipment has a higher energy consumption ratio, while foreign equipment has a lower one.
Manufacturing technique: Since a decanter centrifuge is a kind of separation equipment with high precision machining requirements, the centrifuges manufactured by enterprises without a precision machining capability will suffer from a high maintenance ratio and a restricted handling capacity.

Oilfield Solids Control of Decanter Centrifuge

In the whole solids control system, the drilling mud Decanter Centrifuge is the most important solids control equipment, it is the forth stage equipment and it decides the quality of drilling fluids in a way. The first equipment is oilfield shale shaker, it is one of the most important equipment, too. The second stage equipment is desander, third equipment is desilter. Sometimes they are combined to be as one equipment—drilling mud cleaner.

KOSUN Drilling Fluid Centrifuge is designed to speed up the settling process. The rotating speed is transformed into centrifugal force inside the rotating assembly to accelerate particle settling in accordance with Stoke’s Law. In essence, a centrifuge is a miniature settling pit that alloys very rapid settling of solids under controlled conditions. Though much more complicated than a hydrocyclone, centrifuges have the advantage of achieving extremely fine cut points. Centrifuges can improve the cut point by a factor of 6X when compared to a prototypical shaker/hydrocyclone system and can dramatically increase the drilling fluid life.

Decanter Centrifuge

KOSUN Decanter Centrifuge can effectively remove the harmful solid particles from the oil and gas drilling fluid, improve the mud performance, ensure the drilling safety, lessen the pollution of oil/gas reservoir and reduce the mechanical abrasion of drilling equipment. 1500-3000 rpm centrifuge can separate 2-7μm solid particles. It is an ideal choice for drilling mud purification.

Drilling fluids is important for the whole drilling system, but is too expensive, we usually spend abundant expense for that. But if we clean the drilling fluids and use it for recycling, we can save more drilling cost. At this time, the drilling fluids solids control of the drilling fluids seems to be so important.

Decanter Centrifuge Safety Operation Regulation Tips

In the whole markets, centrifuge or even decanter centrifuge has been used in most fields. There are also mutual types or styles of decanter centrifuge in different fields. We just take oil drilling industry as an example,there are RFD decanter centrifuge, VFD decanter centrifuge, Disc centrifuge, hydraulic centrifuge, etc.

Now KOSUN want to share some necessary tips about safety operation regulation for decanter centrifuge. The following content is about the topic of “6 Tips of Safety Operation Regulation for Decanter Centrifuge”.

Just as we all know that Decanter Centrifuge is one kind of machine revolving at high speed. During operation, revolving drum will generate strong centrifugal force (it is not like the solid control system, to some extent, decanter centrifuge is a core part for a whole solid control system and water based mud unit). To ensure the safety of operators and equipment, the following safety rules shall be strictly followed when using it.

Pay more attention for original Instruction Orders or Steps. Through dynamic balance of revolving drum parts of centrifuge, during assembly, original installation order shall not be changed and there shall be no parts omitted. Threaded connection part shall be installed in place; during assembly, if there is assembly mark, the mark shall be aligned. Before startup, operating pump system shall be inspected and there shall be no water leakage under close state of magnetic valve.
Keep the decanter centrifuge off. Before clamping revolving drum clamp ring and fixing inlet/outlet device and other fastening screws, decanter centrifuge shall not be started.
Before completely stopping revolving drum, any part of equipment shall not be loosened.
During operation, if abnormal vibration of decanter centrifuge is found, power shall be cut off for emergency shutdown. After revolving drum is completely stopped, each part shall be disassembled cleaned and inspected and attention shall be paid to assembly order and position. After the causes of abnormal vibration are found out and removed, reassembly and startup can be carried out. Time interval between re-startup and shutdown shall be more than 4h (This item is also suitable for mud cleaner).
Flame heating or repair welding of main revolving drum parts is not allowed, especially revolving drum body, revolving drum cover and clamp ring.
Use of revolving drum parts and revolving drum parts of other equipment shall not be mixed, even the revolving drum parts with same model.

The above 6 tips or we can call it as steps should be kept in our mind, they can help us improve our working efficiency. Just as I mentioned in the post, you could find more information about solids control system, drilling waste management unit, oil recovery unit, and some other solids control equipment, such as mud cleaner, sand pump, vacuum degasser, cutting dryer, etc. In another words, KOSUN could be your better cooperator.
