The stock of vertical mud agitator discount sales

Mud agitator is an important equipment of mud tank surface product whose function is prevent mud in the tank sediment. Because it locate on the surface tank, so there are many different models of mud agitators because of the different tanks depth and width.

Now, in DC Solid control warehouse, there are 60 sets vertical mud agitators, they are JBQ5.5, JBQ7.5, JBQ15 and ect. All with different shaft lenght accroding to users requirements.

mud agitator

The DCSJBQ Series Vertical Mechanical Agitator is ideal for installations with limited footprint availability. These double-reduction, in-line, helical gear agitators provide smooth, vibration-free operation and efficient mixing, just like the right-angle drive agitators.

Vertically mounted agitators are lighter than right-angle-drive horizontal units, but produce the same mixing results. In some instances, horsepower requirements are reduced due to the 95% efficiency of the helical gearing. Above 7.5 kW mud agitator using turbine worm reduction drive, has the transmission torque, smooth operation, reliable work, etc advantages.

DC solids control equipment for HDD

The main function for a drilling fluid in HDD applications is hole cleaning. It is crucial to avoid cuttings beds forming, a build-up of drilled cuttings on the low side of the hole. Equally as important is promoting hole stability.

solid control equipment

A typical HDD solids control system will employ a combination of shaker, hydrocyclone, mixing, pump and compartmentalized tank technologies. The shaker is vital to the solids control system and is considered the first line of defense. Located directly downstream from the shaker will likely be a hydrocyclone assembly that will employ
desilters, desanders or both.

solid control system

We can achieve stability by keeping the hole full of drilling fluid, but also by maintaining formation integrity with adequate filtration control, encapsulation and inhibition of certain formations.

DC Machinery specialised solids control equipment for HDD. DC machinery also offers a range of centrifuges which remove solids in the drilling fluid down to 5 micron, allowing even greater control of the mud system, minimising dumping and saving costs.

900Pcs Steel frame shaker screen shipped to Poland

Shaker screen is an very important par for shale shakes. Last week, DC solid control shipped 900pcs steel frame shaker screen to a Poland clients. The screen made of steel frame support and 2-3-layers stainless steel screen cloth sticky to the frame.


The frame is the high strength steel box section or flat bar through welding and is attached with multiple high strength support rods. The screen shouldn’t be connected with the frame with metal lining or sticky to the frame directly.

DC Steel Frame Shaker Screen Features & Benefits

1. Configured with high strength steel frame, stiffeners and screen mesh with moderate tension, the performance of the steel frame shaker screen is enhanced largely in strength, service lifetime and flow of drilling fluid that the product can bear.
2. The mesh numbers of the furnished screen meshes are different. Through combining the screen meshes correctly and appropriately, the screening effect can be improved greatly.
3. The wedged rapid tensioning device allows for more convenient installation of the product. The time for stopping the machine to replace the product can be saved.
4. The screen mesh is divided into a number of small independent meshes to avoid local damage and excessive expansion. Meanwhile, the special rubber is available for repairing damage, which can save time and reduce using cost.

Oil-based drilling fluids recycling decanter centrifuge

Decanter centrifuge is the last stage equipment in drilling mud system for solids control and mud cleaning. The superiority of decanting centrifuge is embodied in the solids processing size. Decanter centrifuge could remove the solid particles with size 2-7 microns using the principle of centrifugal action, it is an ideal choice for separating particles in drilling mud.


Always there is a screw pump or submersible pump to feed the mud to Decanter centrifuge. After the drilling fluids being fed into the centrifuge drum, under the function of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the solid discharge export of the small end of the drum and excreted. While the fluids is excreted from the overflow hole of the large end.



Such cycle is to achieve the purpose of continuous separation. High speed decanting centrifuge are more effective for separation of fine solids. Decanter centrifuge is the final processing units in the arrangement of solids control equipment. It could be used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). In oilfield, middle speed centrifuge is used to recycle the the barite and bentonite in solids control system, high speed decanter centrifuge could separate the fine solids in drilling mud after the desilter unit.

Meanwhile, high speed centrifuge centrifuge is always applied in drilling waste management to recover the valuable drilling fluids. Typically, oilfield decanting centrifuge is preceded by gas busters, gumbo removal equipment (if utilized), shale shaker, mud cleaner (if utilized), vacuum degasser and hyrdocyclones.

How to reduce the accumulated sludge in the bottom tank

Mud tank is used for storage, mixing the drilling mud in a drilling mud recycling system, there are various types mud tanks, the normal shape is square mud tank. After a long period drilling operation, there will be some sludge with oil and solids accumulated in the bottom of the mud tank.



Cleaning the mud tank become a big problem, the round bottom tank is better compared with the square bottom tank, but it can not avoid the problem completely. To reduce the accumulated sludge in the bottom tank as less as possible, there are 2 ways:


1. Choose suitable mud agitator and mud gun for better mixing, so it can circulate in the whole system.

2. Use mud tank cleaning equipments. It depends on the solids size in the bottom, firstly you can use a sieve or a shale shaker to separate the large particles, then use the decanter centrifuge to separate the fine particles, the separated solids is dry enough to throw away, the recycled fluids can be re-used to prepare for new drilling fluids. If you do not need to re-use it, you can get it into waste water treatment plant for cleaning.

DC New development DCS585-PTS shale shaker

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.

shale shaker

The DCS585-4 PTS dual-motion shale shaker combines linear and balanced-elliptical motion technology for efficient removal. Using 0.6-hp vibrator motors for unparalleled performance, the shale shaker is especially effective while drilling top-hole sections where heavy, high-volume solids are usually encountered and shakers need to generate high g-forces to effectively move dense solids across the screens.

shale shakers

As drilling conditions change, the shale shaker can be adjusted instantly by flipping a switch on the control box to immediately reconfigure the shaker from linear to balanced-elliptical motion without having to suspend or shut down operations, allowing operators to avoid NPT and unnecessary delays that drive up costs.

The advantages of DC’s shale shaker are structure simple, easy for operation and maintenance, one shaker for various applications by changing different type’s hopper. The cost is also competitive.

Desilters of DC Solid control application and specification

esilter is the third class solids control equipment to treat the drilling fluids. According to the size of the cone diameter, they are divided into Desander and Desilter. Usually the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4” cone
to separate solid-phase particle size 15-47μm in the drilling fluid.



DC Solid control desilters are simple to operate and easy to maintain. Optional shutoff valves on each round desilter cone inlet permit individual cone removal and inspection without interrupting operation of the desilter.

DC Solid control’s polyurethane hydrocyclone offers a high volume 4” cone, while providing contractors an economical replacement for less efficient older equipment. Our unique uni-body construction eliminates excess parts and seams where excessive wear can occur. DC’s 4” desilter cones are available with ceramic inserts for
extreme service.
