Decanter Centrifuges are popular solid-and-liquid separators used in multiple industries for a wide array of products. Decanters are used for the extraction of liquids from large proportions of solids. It makes use of medium-low speed suspension to process larger capacities of solids as compared to a Basket Centrifuge.

A typical example of this type of two-phase separation is the dewatering of sludge from municipal sewage plant or industrial waste water treatment.last week, DC Machinery shipped a set of decanter centrifuge for India wasterwater procesed factory. Th model of the centrifuge is DCLW350-1200 and treating capacity is 15m3/h. With high speed and frequency conversion.

In this case, the residual moisture in the dewatered solids determines the disposal costs and the centrate quality determines the pollution load returned back to the treatment facility. Minimizing both must be achieved at the lowest possible cost, with the lowest possible polymer and energy consumption, with low maintenance costs and with the lowest possible number of required operating staff.

The decanter centrifuge consists of a solid bowl, which rotates and contains the process. A screw conveyor, contained within the bowl, turns at a slightly different speed from the bowl. If you have interest with it, please feel free to contact DC solid control.

A mud agitator, as a part of the mud purification system, is designed to mix mud so that the drilling cuttings and mud & sand in a mud tank do not deposit at the bottom to successfully get through the purification system, with the main function of mixing the drilling cuttings evenly in the mud.

Shale shaker is a most popular equipment uses in drilling mud primary solids control system. According to different processing result and mud condition, the operator may choose the shale shakers with different vibration motions.

Nowadays, DC Solid control company manufacture a set of ATS585-4 shale shaker for a Italy clients who request is the dual motion shale shaker are the linear motion and elliptical motion with 3 Drennan IECEX vibration motors and Warom electric control box.

shale shakers

DC’ s dual motion shale shaker is based on the shaker model DCS585-4 with 4-panel screens that the material of which would be both steel frame and composite material available. Under the screen, there are patented design rubber sealing strips are inlayed into the screen frame which could ensure a better sealing performance.

DC Solid control also developed the own latest version decanter centrifuge and cuttings dryer unit. Please feel free to contact with us for more information.

A MUD GAS SEPARATOR (MGS), or gas buster, is common on most drilling rigs throughout the world. The mud gas separator is used to separate wellbore gas from the drilling fluid while circulating out a kick or circulating any gas present in drilling fluids during drilling or workover operations.


The mud-gas separator also includes a gas vent associated with the main vessel and configured to vent gas from well returns introduced into the main vessel. It also includes a first mud outlet formed within the bottom portion of the main vessel and configured to pass mud from well returns introduced into the main vessel and includes a second mud outlet formed within the side portion of the main vessel and configured to pass mud from well returns introduced into the main vessel.

Design Features
1.Large effective vessel capacity
2.Removal of dangerous H2S and other poisonous gas
3.Baffle plates in vessel
4.Customized specification
5.Backpressure manifold with flare ignition line
6.Effective U-tube or mud seal configuration
7.Skid-mounted design with lay down legs
8.Optional elevating type

Nowadays, more and more drilling company treat safety seriously. Both government and private firm are required to set liquid gas separator and flare ignition device.

Desanders are used to remove suspended solids from liquid process streams. One of the primary applications is to improve the quality of waste water. To retrieve the bentonite used in construction for engineering foundations (like diaphragm wall, piles, etc..) and some underground works.

Desander  and Tank Ready to Export to Malaysia02

Desanders provide with a reliable and compact design which allow reuse bentonite mud after use and contaminated with sand and silt. The laws of each country requires a maximum percentage of sand in the sludge before starting concreting.

Desander of simple cycloning: land recommended for sandy or sandy little bit thin. Sludge only happen once the cyclone after passing through a phase of screening in order to remove larger material.

Desander of double cycloning: need for sand or fine sand with many. Similar to single cycloning, with the difference that the sludge pass twice through the cyclone so as to separate the finest sand and silt even.

Drilling mud system is mainly include shale shaker, desander, desiltr, mud tank, mud agitator, feeding pumps and ect. In order to quick delivery the mud system, DC solid control workers were overtime work during the National Day holidays.

The drilling-fluid system—commonly known as the “mud system”—is the single component of the well-construction process that remains in contact with the wellbore throughout the entire drilling operation.


Drilling-fluid systems are designed and formulated to perform efficiently under expected wellbore conditions. Advances in drilling-fluid technology have made it possible to implement a cost-effective, fit-for-purpose system for each interval in the well-construction process.


DC Solid control is able to customize its system to produce the arctic solids control system which is solely applied under extremely cold temperature to meet the requirements of the polar cold ( minus 40 degrees centigrade ) working conditions.

Many of our readers might not realize that desander cones wear out, and when they need to be replaced. If your desander cones are not performing like they used to, and you are seeing more liquid than sand coming out of your cones, it may be time to inspect them.

desander cones

Inspecting your desander cones is important and easy to accomplish. To inspect your desander cones, first remove them from the manifold. Remove the clamp that bands the top and bottom half of the cones together. The two halves will split apart. Look inside of the bottom half towards the output nozzle. If you see grooves or wear it may be time to replace your desander cones. The top half of the cone will also show wear around the outside edges near the input jet.


Both the top and bottom half of the cone need to replaced if there is excessive wear. When the sand enters the cone at a proper psi, the pressure creates centrifugal force which pushes the heavier sand to the outside if the cone. This pressure forces the sand down the smooth sodes of the cone. The lighter, clean mud goes back up the center of the cone and into the tank.

As the sand swirls around however, it carves grooves on the inside of the both the top and bottom halves of the desander cone. The grooves disrupt the centrifugal flow of the sand and then will get mixed back in with the clean mud. This means your desander cones have lost their efficiency and may need to be replaced.

DC Machinery developed the horizontal drill mud gas separator but also supplies any custom units according to customer specifications and preferences. We also provide complete system gas handling analysis to establish the capacity of the separators in conjunction with the vent line and mud seal.


There are three types of mud gas separator used in the oil well drilling. Closed bottom, open bottom and float type. however the closed bottom is most popular one. It is closed at vessel bottom with mud return line directed back to the mud tank. Mud leg is maintained in the separator by installation of an inverted U-shaped bend in mud return line.


There are three major types of mud gas separators that Tech-Fab fabricates:

Open bottom: These separators are often called “poor boys,” and immerse the bottom of the machine in the mud deposit.
Closed bottom: A closed bottom mud gas separator features a sealed base, which directs the mud return into the storage tank.
Float: The float design is similar to the closed bottom type of separator, except that it has a valve rather than a permanently sealed line for the mud return. Fixed or elevated pedestals are also used to mount the base.

DC Machinery offers a range of mud gas separators and degassers for clients engaged in drilling and extraction activities. To learn more, or to request a price quote, please contact us
