Introduction of the desander cones for solid control

Desander is used as the 2nd stage of solids control for drilling fluids, which makes separations between 45 and 75 μm. DCCNQ Series Desilter is used as the 3rd stage of solids control for drilling mud, which makes separations between 15 and 45 μm.

Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. We commonly used 8 “and 10” cones desander to separate solid-phase particle size 47-76μm in the drilling fluids.



Desander, as stated earlier, have no moving parts. The larger the internal diameter (ID) of the desander is, the greater the amount of fluid it is able to process and the larger the size of the solids removed.

Desander (10 in.cone) are able to remove roughly 50 percent of those solids within the 40-50 micron range at a flow rate of 500 gallons per min (gal/min), while desilter (4 in. Cone) are able to remove approximately 50 percent of those solids within the 15-20 micron range at a flow rate of 60 gal/min. Micro fine separators are  able to remove around 50 percent of those solids within the 10-15 micron range at a flow rate of 15 gal/min.



Desander is typically positioned next-to-last in the arrangement of solids control equipment, with decanting centrifuge as the subsequent processing unit. Desander are preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud cleaner (if utilized) and vacuum degasser. Desander is widely used in oilfield

Produce the High quality Shale shaker screen

Shale shaker screen is a kind of screen that installed in shale shakers. It is widely used in oil extraction and drilling operations to filter drilling fluids, oil and mud.


DC shale shaker screen is made of two or three layers of stainless steel wire cloths with different meshes. This structure make shaker screen have good filtering accuracy. Different kinds of shale shaker screen has different features and processing accuracy. For example, wave screen has the best processing efficiency. Steel frame screen with steel support can bearing the highest weight of drilling fluid. You can choose the suitable screen depending on the drilling conditions.

Get more information about the DCJBQ series mud agitator

The agitator is an important part of the mud solids control system. It is mounted on the circulating tank. The vanes of the agitator are designed for stirring mud slurry in an open tank.

DCJBQ series slurry mixer adopts circular arc cylindrical worm reducer, with circular arc cylindrical worm in shaft section and conjugate circle with turbine teeth. Therefore, concave and convex teeth have reliable performance, high efficiency and compact structure,large stirring intensity and wide sweep range.

drilling fluid agitators

The JBQ series mud agitators are suitable for the mixing of oil drilling fluid with compact structure and small floor area. The mud agitator for drilling fluids above 7.5 kW is driven by turbine worm reducer, which ha?s the advantages of high transmission torque, stable operation and reliable operation.

mud agitator

The characteristics of mud agitator from DC Solid control:
1. Helical-bevel gearbox
2. Explosion-proof electric motor
3. Able to process 20 ppg drilling fluids
4. Power available ranging from 2.2 to 22KW
5. Compact, quiet, smooth and easy to maintain

DC Solid control is the famous mud agitator manufacturer and mud agitator supplier in China. and have more types mud agitators used in the mud tank of drilling mud system or other industry. Such as Horizontal Mud Agitator and Vertical Mud Agitator for Mud tank. DCJBQ series mud agitator had been exported to 40+ countries and service for many customer. Competitive Prices of Mud Agitator and good service is the important factor.

10 sets JBQ7.5 mud agitators shipped to UAE

This Monday. DC Solid control shipped 10 sets mud agitator to UAE clients who are our old clients. They purchased 1000 pcs shaker screen in May this year. Mud agitator is used in the surface mud tank to suspend solids and maintain a homogeneous mixture throughout the mud solids control system.

Our mechanical mud agitator is driven by an explosion-proof motor coupled to a gearbox that drives the impeller & shaft. The impellers transform mechanical power into fluid circulation or agitation. The objective is to achieve a uniform suspension of all solids.


Now we supply the motors vary from each other as well. Such as30 HP motor of 380V/50Hz/3Ph and 4 poles. For mud process, usually we request agitator rotate at 60~70 rpm, thus we’ll find proper gearbox with certain reduction ratio. (Of course, the rated speed was calculated well prior to model selection under torque demand, and so

mud agitator

Solid Control Mud Agitators act as mud mixers on mud tank. On a usual process these agitators should rotate at 60-70 rpm. Our high performance equipment is appreciated among clients all over India. If there is a large quantity of mud present in the site then large torque mud agitator will be required.

We suggest the customers to choose the mud agitator according to the size of tank along with torque level. Mud Agitator Manufacturer in Hyderabad is the name suggested to our services by all our previous customers.

Drilling fluid centrifuges Made from DC Solid control

Centrifuges are another essential part of any effective solids control system. They have a great advantage of achieving extremely fine cut points. The rotating speed is transformed into centrifugal force inside the rotating assembly to accelerate particle settling. Essentially, a centrifuge acts as a small settling pit which alloys rapid settling of solids under controlled conditions.

drilling fluid centrifuge

In order to achieve effective solids control there are several steps that should be taken. The first and most critical step is to obtain an effective, dependable and durable solids control system. Special attention should be given to ensure that the system is hydraulically balanced, capable of making both a scalp cut and a fine cut, and that the system has sufficient drilling fluid mixing and re-circulating capacity.

Decanting centrifuge key part is screw conveyor and transmission. When centrifuge work, drilling fluid will flow into centrifuge through drilling fluid input. Then the roll bowl will increase speed and fluid will flow into centrifuge through one fixed input pipe. Since rolling bowl rotate at rather high speed.

Drilling mud decanter centrifuge are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used drilling mud, including those based on water/synthetics and conventional oil-based drilling fluids. Please contact DC Solid control to get more information about the drilling fluid centrifuges.

Do you want to know more about DCQJ series mud cleaners

Mud cleaner combines a hydrocyclone system (desander cone and desilter cone) with a shale shaker to help remove the fine drilled solids from the drilling fluid. It consists of a two-stage separation process that using a combination of hydrocyclones mounted over a shale shaker to operate as a single unit.

Mud cleaner is a mature product in our company, we can design customized cost-effective mud cleaner for customer’s special needs.Our mud cleaners call meet almost all needs for oil&gas well drilling fluids treatment system and HDD Mud Recycling System. DCQJ series mud cleaner including desander, desilter, pressure gauge. There is butterfly valve between feeding inlet and discharge output.

mud cleaners

One advantage of the mud cleaner is that the shaker screen only processes ab^’ i i to 2 gallons for every 50 gallons passing through 4-inch desilters. The D50 cut point of a 4-inch hydrocyclone processing a weighted drilling fluid may be as high as 60 to 70 microns. Therefore, most of the weighting material is not presented to the mud cleaner screen.

Usually, the screen discharge from a 200-mesh mud cleaner screen has less whole mud associated with it than a primary shale shaker discharge. Measurements show, however, that the discharge from a 200-mesh shale shaker screen and a properly treated 200-mesh mud cleaner screen are similar.
