Desilter and desander unit mud recycling system is widely used in pilling project recent years. This month, DC Machinery designed a set of 250m3/h desilter unit mud recycling system for a Singapore clients.


Desilter Hydrocyclones are used to provide efficient and reliable separation of sand and solids from Produced Water, Condensate and/or Gas streams. They have proven to be a valuable part of pilling production facilities, by providing:
• High Efficiency Solids Removal,
• Compact, small footprint,
• Cost effective protection against erosion damage,
• No moving parts and minimal maintenance,
• Highly consistent performance.

The desilter Cyclone Liner size and type selected is dependent on the process fluid, temperature, pressure and the concentration and type of solids present in the Liquid Water. If you have request, please contact DC Machinery office.

Following the high environmental protection requirements, the solid control equipment is widely used in pilling project. Especially the mud cleaner with desander or desilter and shale shaker is also a very important part for clients to recycling the piling drilling mud bentonite.

DC Machinery is a construction company specialized in pile drilling. We are executing construction of piles of 2000mm diameter and 54meter depth. Please suggest equipment for following purpose;


Model: DC100 Desander Unit
1. Treating capacity:100m3/h
2. Separation particle size:≥74μm
3. Vibrating motor Pump motor
4. Desander cone:DC200 x2
5. Desander unit Weight:2000kgs

DC is now on promoting this type economic mud recycling system, for more information, you may sent inquiry to our mailbox.

DC Oil mud equipment company provide the Desander Cyclones are a proven method of providing efficient and reliable separation of sand and solids from produced water, condensate and/or gas streams.

Multiple Desander Cyclones are typically installed in a single pressure vessel and located downstream of 3-phase separators to remove solids before the fluids undergo further processing to prevent damage, fouling and blockage in downstream equipment. Desander Cyclones provide:

1. High efficiency solids removal
2. Very compact solution
3. Cost effective protection against erosion damage
4. Low OPEX
5. Low maintenance, as there are no moving parts
6. Highly consistent performance
7. Well-proven technology
8. Suitable for use on floating systems

DC oil mud equipment offer  Desander Cyclones in our tungstone materials range so you can be sure that they are suitable for your application no matter how severe the service

Desander Cyclones are pressure-driven separators that require a pressure drop across the unit to cause separation of the solids from
the bulk phase (water, oil or gas, etc).


The inlet stream (containing solids) enters the cyclone through a tangential Inlet Section under pressure, where it is forced into a
spiral motion by the cyclone’s internal profile. The internal cone shape causes the spinning to accelerate, which generates high
centrifugal forces, causing the denser solid particles to move to the outer wall of the Cyclone, while the Water/Oil/Gas is displaced
to the central core.


Solids continue to spiral down along the outer wall of the conical section inside the Cyclone to the Outlet or Underflow, where they exit. It is typical to collect the solids in a closed underflow container or vessel, and periodically dump these solids.

De-sanded Water/Oil/Gas in the central core section reverses direction and is forced out through the central Vortex Finder at the
top of the Cyclone as the Overflow.

A desilter is used to separate silts from drilling mud. The cut point can be as low as 4“. As muds are being used in drilling operations, they are contaminated with silts. In order to use again these mud, it is necessary to separate silts and also to recycle mud to dispose them at the end of work duty.


Today, DC Machinery delivering a mud desilter to HongKong and used for building construction. This is the 20th desilter shipped to Hongkong who are our regular clients.

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 equipment.


DC Mud desilter has the advantages of 100% Polyurethane(PU) Material for desilter cones with longer using life. Flexible options for 1 or 2,or 3 for different capacities and Tangentially blended into the cone entry as a narrow rectangle to minimise turbulence in the upper section of the cone, allowing the solids to move quickly to the cone wall.

Desilter is an very important part of solid phase removal unit, we solid 24 sets of desilters to Hongkong construction site last year. And recent days, we customized 2 sets desilter spare parts according to user requirements.

The desilter are designed to remove silt-sized (20 to 74microns) solids from drilling fluid. DC Solid control desilter are simple to operate and easy to maintain.


DC Polyurethane hydrocyclone offers a high volume 4″ cones, while providing contractors an econimical replacement for less efficient older equipment.

Features of DC desilters
Silt-sized solids removal (12 – 74 microns)
80 gpm per cone at 75 feet of head
Variable size apex inserts
Available with and without a ramp in the feed inlet

Desilters are available in a large range of configurations including stand alone, over a shaker as a mud cleaner or packaged with a supply pump as a mobile desilting unit. Please contact your DC office to discuss applications and appropriate technical specifications.

Desilter is a third separation equipment of solid control system, which also can be used in building construction fields. Recent days, DC Machinery shipped 6 sets desilter to foreign clients used in building construction fields.

Usually the cone diameter is less than 6″is called Desilter. 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 Mud Desilter Features & Benefits
1. 100% Polyurethane(PU) Material for desilter cones with longer using life
2. Clamp type for easy maintenance
3. Compact design with small footprint.
4. Flexible fast connection are available for user friendly assembly.
5. Shutoff stainless steel ball valves available for option on each cone inlet permit individual cone removal and inspection without interrupting operation of the desilter.

DC solid control engineer designed a small desander system for Singapore clients which is mainly used for urban architecture field.

The samll desander system mainly include a desander, mud tank and a feeding pump.

The desander matched 2 pcs 10″ hydrocyclone, the material of the hydrocyclone is iron that is customized according to the clients request. The mud tank dimension is 2.5×2.2×1.8m, painted the specified-Sigma brand. The feeding pump is DSB3X2-12 sand pump, with explosion proof and IECEX certificed of the motor.


The main advantages of the small desander cleaning System which designed by TangShan DaChuan Machinery lie in organically combining the advanced mature technology in petroleum drilling and related hydrological, geothermal construction, make full use of existing equipment, greatly improving the drilling efficiency, shorten the construction cycle.

DC Solid control also can design different model mud cleaning system for HDD, CBM Trenchledd and drilling oil field to recovey the drilling mud. If you have interest with us. Please contact us freely.

Desander and desilter is an very important part of mud recycling system. DC Soldi control can provide all kinds of cost-effective capacity desander and desilter.

Desanders are what larger diameter hydro-cyclones are typically referred as, and will be the next step in solids removal after an initial scalping shaker pass. Desanders are capable of handling large flow rates, up to 500 gpm per cone, but do not offer as fine of a cut. The underflow will be recirculated over a shaker and processed again while the overflow will be free to move on to the next stage, typically a desilter.


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. The Underflow will be recirculated over a shaker and processed again while the overflow will be free to move on to the next stage, whether it’s a centrifuge, chemical treatment, or a finished product.
