Why must use the decanter centrifuge in working site

The structure and performance of drilling fluid centrifuge all have a bid progress, our country have already special mud centrifuge designed accords the characteristics of drilling fluid. Drilling fluid centrifuge is the most difficult master and the structure is complex equipment. But it is the key equipment except shale shaker.

The initial stage of decanter centrifuge became solid control system is the chemical centrifuge is introduced. Not only the separation size or capacity all can’t meet the requirement of drilling fluid solid control technology.  Now decanting centrifuge has the characteristics.

The capacity from small to large, foreign has already the centrifuge can dispose 4T material per hours.

It has common centrifuge and high speed centrifuge. The common centrifuge can’t solve the whole problems of drilling fluid. High speed centrifuge can dispose drilling fluid, the disposing drilling fluid become dry material and water two parts. Using it to process drilling fluid can maintain environment and ecological environment.

The transmission structure evolves ingle motor drive from double motor.

The prime centrifuge is chemical centrifuge, the drum and conveying screw are all use stainless steel to manufacture. In recent years we have already research the drilling fluid solid cobtrol special centrifuge with the material of drum and conveying screw is carbon steel, so the cost is decreased.
The abrade level of drum and conveying screw has the structure of using bonding method dressing pad the ceramic disk, it can improve the service life of centrifuge.

Drilling fluid centrifuge for Unweighted and Weighted Drilling Fluids.

Drilling fluid centrofuge is the 4 stage equipment of the oil& gas drilling fluid circulating system. The centrifuge suck the mud from the compartment receiving the discharge from the desilters and mud cleaners, and the returned stream is directed to the next compartment downstream.

DCLW centrifuges can be used in Unweighted Drilling Fluids and Weighted Drilling Fluids. Following is the maters of the centrifuge used in the different materials.

decanter centrifuges

When centrifuging the unweighted drilling mud, keep in mind the following:  the centrifuge with High G force as the solids loads are low. Adjust the weir to a deep pool to maximized solids separation. Control a smaller mud feed rate to increase residence time Operate centrifuges in parallel, not in series if multiple centrifuges are required.


With the unavoidably higher solids content of weighted mud, the increase of gel strengths and viscosity, as well as the degradation of ? quality associated with the diminution of particle size with time, can become a serious problem. The problem is caused by the increasing concentration of colloidal and near-colloidal particles that are  to be separated from the base. Centrifuges are used to selectively remove these solids.

With high solids content of weighted fluids, torque is a problem when processing it, the following is some advice when operating the centrifuges. Increase pond depth. Reduce in rpm or run a higher conveyor differential. Process the mud at a reduced feed rate Centrifuges.

Decanters are equipped with either fixed or variable back drive. The scrolling speed -(relative conveyor speed) can be changed in a matter of seconds by operations of a simple control switch. The optimum scowling speed is selected in each case according to solids load, required separation efficiency and required underflow density.

Actually, in drilling rig solids control system centrifuge is the most complicated one. It is rather difficult for operator get leagal operation, etc. However, in long term its important position is following shale shaker subsequently.

Complementary use of hydrocyclones and centrifuges

DC Machinery offers solutions for all of your Classification needs from hydrocyclones and centrifuges to classifiers and heavy media separation.

Hydrocyclones are related to centrifuges in that both are intended to separate heavies and lights by application of centrifugal force. The key difference is that hydrocyclones are passive separators capable of applying modest amounts of centrifugal force, whereas centrifuges are dynamic, spinning separators that are generally able to apply much more centrifugal force than hydrocyclones.


Another key difference between hydrocyclones and centrifuges is cost. Centrifuges are expensive precision rotating machines that often need sophisticated control, whereas hydrocyclones have no moving parts and usually no controls at all, so they are lower cost devices.


Hydrocyclones and centrifuges are complementary rather than competing devices. If gravity alone will settle a significant portion of your solids in a minute or two using a quick bottle test, you should investigate hydrocyclone separation. If settling takes much longer than this, then you may need a centrifuge or other separation method.

Advantages of using decanter centrifuge for oilfield

Having effective solids control equipment is very important for any oilfield. Without having proper solids control, drills can encounter a variety of problems.

With a horizontal oilfield decanter centrifuge, the mixture of drilling liquid and cuttings and solids enter into the centrifuge. When it enters the centrifuge, it gets spun at an extremely high rate, sometimes as much as 3000 times the force of gravity. When this happens, the solids will separate from the liquids. When they are separated, the drilling liquid can be decanted and eventually returned to the mud tank where it can be replaced into the borehole for efficient drilling.

centrifuge supplier

One of the biggest advantages to having an oilfield decanter centrifuge is the size that it takes up. Compared to other solids control equipment, a centrifuge takes up less real estate. On many oilfields the site footprint is not large enough to support a wide range of solids control equipment. A centrifuge is highly effective and efficient so you can separate solids from drilling liquids even on small drilling sites.

The Use of Decanter Centrifuges for Unweighted Drilling Fluids

Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (mud). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.


When centrifuging the unweighted drilling mud, keep in mind the following:

Operate the centrifuge with High G force as the solids loads are low
Adjust the weir to a deep pool to maximized solids separation
Control a smaller mud feed rate to increase residence time
Operate centrifuges in parallel, not in series if multiple centrifuges are required.
The Use of Decanter Centrifuges with Weighted Drilling Fluids

DCLW series decanter centrifuges are specially designed for the drilling mud solids control. The effective centrifuging and fine drilled solids separation can remove significant quantities of inseparatable solids. This significantly reduces the tranditional dilution requirements and drilling waste volume for disposal.
