Hydrocyclonde desander and desilter manufacturer from China

Hydrocyclones is an important part of desanders and desilters. Hydrocyclones have a wide variety of applications in many industries, particularly in oilfield application processing. The hydrocyclone is a continuously operating classification device with no moving parts. It utilizes fluid pressure to cause rotational forces that accelerate the settling of particles according to their size, shape and density.


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. Based on customer requirements and capacity, we can select groups of cone into Desilter. DC Desilter works very well with Solids control system other equipments.


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

The design of desander and desilter can be said not too hard. However, for many people initially come to this industry, it is rather profound. If you do have interest or any question, please contact DC Solids Control to get more puzzles solved. DC will give you more professional solution through experienced solids control engineer proposal

DCDS Series high quality desander China supplier

Desander is used in the second phase of drilling fluid purification to remove nocuous solid, stabilize drilling liquid properties and improve drilling efficiency. The larger internal diameter of desander is, the greater fluid capacity is processed, so for desander with cone more than 10 inches, it is able to remove about 50% of solids within 40-50 micro range at 500 Gal/min.


DCDS series desander overcomes shortcomings of the original sand removal process. The hydrocyclone of desander is provided with a rotating component, and its cylindrical wall is with a separation window. The upper cylinder wall of the rotating member, a set of tapered grooves and liquid inlet pipe constitute drilling fluid lifting component. Impeller of desander is set at the interior of the component, and sand regulator controls the amount of sand.


Desander includes two 12-inch(305-mm) diameter polyurethane hydroclones slant mounted over the shaker. Each desander clone includes four replaceable wear resistant polyurethane sections that are joined together with quick release stainless steel clamps. The desander is furnished with an 8-inch(203-mm) diameter feed manifold and a 10-inch (254-mm) diameter discharge manifold and a 0-60 psi (4.1-bar) pressure gauge. The desander also includes a solids discharge trough to distribute the hydrocyclone underflow evenly onto the screening surface.

DCDS Series Mud Desander is widely used in oil & gas drilling, Drilling Waste Management, city bored piling, tunneling construction, trenchless HDD, mining, Oil Sludge Dewatering Systems, Coal Bed Gas Solids Control System, Oil Mud Separation, environment protection, Water Drilling etc.

Desander for treatment of waste water industry

Desanders are used to remove suspended solids from liquid process streams. One of the primary applications is to improve the quality of waste water. Treatment of waste water normally involves multiple process steps to remove the impurities and ensure that the final effluent discharge is compliant to regulatory specifications.


A desander has an entry port near the top on the side of the vessel, a hydrocyclone central component, and two discharge points (one on the top of the vessel and one on the bottom). The hydrocyclone is oriented so that the wide opening is at the top and the narrow opening at the bottom.


We offer highly technical expertise, excellent quality solid control equipment and a personalised approach to your business’ needs. We can easily combine our solutions to suit your specific business, compliance and investment requirements.

The spare parts of desilter cones delivery to Singapore

The hydrocyclones also called cones are the most important parts of desander and desilters. Today, DC Solid control shippped 100sets desilter hydrocyclones to Singapore clients by Air.

desilter cones  (1)

Desilter cones are typically 4”, but some client will request 3”, 5” as well. So it is rather flexible on capacity configuration. Desilter can be fit with the bottom shaker or not. Or it can be combined with shaker and desander together to be the mud cleaner. We call desilter as the 3rd phase solids control equipment.

desilter cones  (2)

The 4″ drilling mud desilter cone with the features of Silt-sized solids removal (12 ~ 74 microns). 100% polyurethane hydrocyclone. 80 gpm per cone at 75 feet of head. Variable size apex inserts. Available with and without a ramp in the feed inlet. Flexible fast connection is available for user to assemble and compact design, small footprint.

Contact us if you have requirements of any sizes of hydrocyclones.

Desander and desilter were tested in DC factory

In order to ensure the working efficiency of the desander and desilters. Our inspction department must test it in our workshop before delivery. Today, the desilter and desander were tested in the testing plate.

The desanders make separations between 40 and 100 microns and offer the flexibility ­­of mounting either one, two, or three 10” desander cones over a cone underflow pan. The underflow can be discarded or directed onto a vibrating screen for further processing. DC desanders are also available in vertical or inclined manifold stand-alone models, or for inclined mounting on our shakers.

desander desilter

The desilters are designed to remove silt-sized (20 to 74 microns) solids from drilling fluids. DC 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.


Besides, we send the working video of the desander and desilter to the user and got their satisfication. DC solids control produce the desander, desilter, centrifuge and complete line solids control equipment. Please contact us for the high quality product.

Universality of mud desander unit

Mud Desander also called Desander. It is composed of hydraulic desander hydrocyclone, shale shaker and cyclone pipe. Mud desander is widely used in HDD, CBM, water well drilling, building construction and ect.


A mud desander is a hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shakers and vacuum mud degassers, but before the desilters or mud cleaners

Desander uses centrifugal force to separate. Desander uses centrifugal pump to supply mud, then the mud flow into hydrocyclone along tangent of cyclone, and the mud’s structure was destroyed under the action of centrifugal force. Under the action of gravity, solid particles along the inner wall sink spirally and was discharged from the bottom of cyclone then falls on the following shale shaker, liquid was discharged from the top of the cyclone.

Desander unit that efficiently removes sand and silt-sized particles down to a 70 micron cut. Customized mud desanders are available depending on the volume of the mud being cleaned.

Use features of mud desilter compare with desander

Desilters are similar to desanders with the only difference in the size of sand particles that are removed by two devices. Desilters remove sizes which are 20 microns or lesser whereas desanders removes the sizes from 50 to 70 microns.

Desilters are what smaller diameter hydrocyclones are typically referred to as, and will generally be used directly after a desander. Occasionally desanders will not be necessary and the desilter will operate immediately after the scalping pass. While desilting cones can achieve a finer cut, down to 20 micron, than desander cones they cannot process at as high of a rate per cone and are headered together in order to meet the desired throughput.


Advantages of Mud desilter

But recent days, DC Solid control company got an order of 6 sets old-fashioned desander and desilter used for HDD industry.

Desander is installed on top of the mud tank following shale shaker and vacuum degasser, but before the desilter. Desilter is installed on top of the mud tank following Desander. They also can be installed completely: in this case, they are installed on one deck shaker and called mud cleaner or mud conditioner.

desander desilter

Desander removes the abrasive solids from drilling mud which cannot be removed by shale shakers. Normally the solids diameter for desander to be separated would be 45~74μm, and 15~44μm for desilter.
