Normaly working flow of hydrocyclone desander
A hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shakers and degassers, but before the desilters or mud cleaners.
A volume of mud is pumped into the wide upper section of the hydrocylone at an angle roughly tangent to its circumference. As the mud flows around and gradually down the inside of the cone shape, solids are separated from the liquid by centrifugal forces.
The solids continue around and down until they exit the bottom of the hydrocyclone (along with small amounts of liquid) and are discarded. The cleaner and lighter density liquid mud travels up through a vortex in the center of the hydrocyclone, exits through piping at the top of the hydrocyclone and is then routed to the mud tanks and the next mud-cleaning device, usually a desilter.
Various size desander and desilter cones are functionally identical, with the size of the cone determining the size of particles the device removes from the mud system.
Multiplicity mud cleaner manufactured by DC Solid control
With the combination of a desander and desilter mounted over a powerful multi-functional shale shaker, DC Solid control’s line of mud cleaners offer both high performance and versatility for the operator.
This integration of advanced equipment puts forth a unit that can handle large volumes of circulating fluids and is able to retain fluid integrity. Features such as our wedge-lock fastening system, mud bypass gate, and explosion proof enclosures all allow for ease of use. Our pride is truly expressed in our work through our craftsmanship, research, design, and the overall practicality of our equipment.
With our in-house engineering and design capabilities, DC Solid control can integrate any number of hydrocyclone arrangements with any of our shakers. In all cases, DC Solid control’s hydrocyclones come with polyurethane bodies, where erosion resistant inserts are available. Standard hydrocyclone cone sizes available include 4”, 5”, 10”, and 12” and can be provided in arrangements of one to 20 cones.
You are welcome to call Dachuan Machinery to get more infos about the mud cleaner and we are appreciated to supply the cost-effective products and service for you.
A DCSLH jet mud mixer delivery to foreign clients
Jet mud mixer is an auxiliary equipment of drilling mud system which is the equipment to match with the drilling solids control equipment, regularly used to mix and adjust the proportion of drilling fluid, changing the density and viscosity etc.
Today, DC Solid control shipped a DCSLH150 jet mud mixer for a French clients. DC jet mud mixer is made up of one set(or multi-set) centrifugal pump and one set(or multi-set) jet mixing hopper installed in a base with pipe valves. Its hopper and centrifugal pump either can be combined to use or be installed separately.
DCSLH series jet mud mixer is matched with other drilling solid control system. It’s safe and reliable, and easy to move. It can enhance dispersion effect of material, improve pressure head of mixed liquid, make the material recycle and mix enough in the mud tank.
Four models of jet mud mixers can be provided By DC Solid control. DC Solid control also can provide jet mud mixer as per customer requirements.

Why vertical cutting dryer can used for drilling cutting management system
The vertical cuttings dryer is aimed to reduce the liquid content of drill cuttings which is safe to discharge to the environment or as preparation for bio-remediation. The criteria may be set at a local/national level by economical or legislative requirements.
The purpose designed cuttings dryer is an absorption of advanced technologies at home and abroad. It has very strong structure and excellent separation result. The drier is reliable and trustful for your choice of cuttings management applications.
1.“G” force of 420 G’s
2. Proprietary screen design minimizes particle plugging
3. Air knife around the unit assists in screen basket cleaning to reduce screen blinding / caking
4. Improved rotational balance minimizes wear on rotating parts and lowers noise
5. Individual oil lubrication system allows it to work in high temperature environment
6. Screw pump is used to clean the dryer unit, preventing the solids accumulations
7. Screw conveyor installed under the dryer to pick up the dry solids for continues operation
Vertical cuttings dryer could be regarded as a vertical centrifuge, the discharged cuttings transfered by the auger get into the Vertical cuttings dryer from the opening on the top, under the function of centrifugal force produced by rotation of the screen module. Liquid flow out from the opening at the flank side while the solids discharged out from the outlet at the bottom of the cuttings dryer.vertical cuttings dryer moisture percentage, 6-10%, that means there is no flowing water, so it could be transported easily.

DC compact Solid control system for HDD project
Relative to the use of drilling fluids within the oil and gas industry, the use of drilling fluids within the horizontal directional drilling (HDD) industry is new.
Even today, the amount of research and development aimed at HDD drilling fluids is considered a rounding error in the oligopoly of drilling fluid manufacturers.
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. Though still considered rare, centrifuge-enable solids control systems are becoming more popular. By adding a centrifuge, the solids control system will achieve the highest level of cut available within the market today.
Before choose HDD system,we need make sue how much capacity the drilling will need,and the material we need do solids control,to do recycling more and reduce the waste,also friend for environment.
DCSLH series Jet mud mixer designed by DC Solid control
Jet mud mixer is an important auxiliaries part and special equipment to prepare and increase the drilling fluids weight by adding and mixing bentonite, change the fluid density, change the mud density, viscosity, and dehydration.
DCSLH series compact structure jet mud mixer connected by manifold valve, jet mud mixer is composed of sand pump, jet hopper and mixer. Four models of jet mud mixers are available as below. DC can provide jet mud mixer as per customer requirements.
Jet mud mixer can be mounted on one base including the pump and hopper. We also can set hopper on tank top but the pump on one separated base on the ground then the pump and hopper will be connected with one hose or an steel pipe with elbows.
Jet mud mixer can be used in onshore and offshore oil&gas drilling, CBM exploration, HDD,waste management, etc. process system. Jet mud mixer is a popular device to mix drilling fluid. If there is blow out or other emerge accident the mud mixing pump can configure large quantity weighted fluid very soon.
DC’s new Jet mud mixer specializes in simple structure and easy manipulation which can satisfy the drilling fluid’s need on weighting and compounding from 1500m to 9000m depth. DC’s jet mud mixer can be customized to be double jet mud mixer based on customer’s need.
