DCQJ mud cleaner is a normal model of our company,we can design customized cost-effective mud Cleaner for customers special needs.Our mud cleaner can meet almost all needs for oil & gas well drilling fluids treatment system and HDD Mud Recycling System.

mud cleaner

Traditional mud cleaners use multiple 4 or 5cyclones, mounted over a vibrating screen, and are able to effectively process 400-600 GPM. DC solid control can design many sets desander and desilter hydrocyclones according to different using request.

DC Machinery used at home and abroad the most advanced mud cleaner production process, to ensure that the production of powerful, compact structure, convenient operation, easy maintenance of drilling fluid mud cleaner.

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.

Dewatering of sludge centrifuge from DC Solid control

DC Solid control company can design and manufacturer the centrifuge specialized in Dewatering of sludge.

Working pinciple:

The sludge is concentrated in the concentration section and then transported to the dewatering section. During the progress of the sludge,the pressure and the pitch are gradually reduced, and the back pressure plate is blocked, resulting in a great internal pressure, To achieve the purpose of full dehydration.Centrifugal sludge dewatering machine through the conditioning agitation tank, concentration system, sludge alarm distribution, sludge dewatering, filter cloth cleaning, sludge cake removal complete just sludge dewatering process.

Sludge dewatering machine is a continuous operation of the sludge treatment equipment, due to the mud moisture content is low, stable operation, with a small energy consumption, control and management is relatively simple, easy maintenance.

Best Quality HookStrip Flat Shaker Screen of DC Machinery

The hook strip shaker screen has many advantages. Due to the difference in mesh number of the screen meshes, the user can get more excellent screening effect by using the screen meshes with rational and correct arrangement.

hookstrip shaker screen

The metal lining is designed with different hole size to match with screen mesh of different mesh number. On the basis of ensuring adequate strength, we strive to obtain the maximum effective area of the screen mesh. Meanwhile, the integration of the bottom coarse wire mesh with small mesh number and metal lining enhances the strength of the whole product and prolongs its lifetime effectively.

Features of HookStrip Flat Shaker Screen of DC Machinery
Provides improved energy transfer from the shaker basket to the screen, thus faster solids separation
Improves screen life, thereby providing replacement cost savings and downtime minimization
Eliminates the need for crown rubbers, which eliminates the cost of replacements
Individual seals around the perimeter of the screen:Eliminates leakages
Patented pin-and-hole screen securing system

Besides, Hook strip shaker screens have many different type, soft hook strip, metal back (back bounded) hook strip; the metal back hook strip can be flat type or Pyramid (PMD) type. And the hook can be any structure according the design of the shale shaker.

Mexico drilling service company examine shale shaker in DC workshop

In the early winter, We welcomed our new business cooperator from Mexico who is in a influential drilling service company. They want to change their ZJ50 drill rig solid control system in 2017. So they placed a trial order to us.

They only orderd a shale shaker and a mud cleaner in this trial order want to know more our service and technology level. According to about 1 month communication and production, they were very satisifed with our professional technology level and All-wave service.
So they are planing the ZJ50 orders once they coming back to Mexico.

Decanter centrifuge used in piling construction fields

Decanter centrifuge is a separation equipment used in many fields, such as, oil& gas, HDD, and piling constrction field. Recent days, DC Solid control got an order of decanter centrifuge used in piling construction in Indonesia.

The one that we proposed is a professional model for piling construction wastewater process system, which already has the mature technical guidance and rich experience in the fields. So the Indonesia client was very satified with our decanter centrifuge process effect and after sales service.


Besides, I detailed introduce the work principle of the professional decanter centrifuge to the customer. Separation takes place in a horizontal cylindrical bowl equipped with a scroll conveyor. The processing material is fed into the bowl through a stationery inlet tube and is smoothly accelerated in the accelerate chamber.

Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl.

You are welcome to contact Tangshan Dachuan Machinery to get more detailed infos, we will supply our best service for you.

DC parts solid control equipment at TianJIn Railway station

At the begaining of Nov, DC deliveried batch solid control equipment to Kyrghyzstan. The order placed by our old partner who is a big contract company in Kyrghyzstan.

Performance characteristics of mud gas separators

In a well-controlled situation, well bore fluids are directed through the choke and kill manifold to circulate hazardous gas in a safe and controlled manner using the Mud Gas Separator.

In the oilfield, the mud gas separator is sometimes known as ‘poor boy degasser’ or ‘gas buster’. They may be vertical or horizontal in design.

A Vertical separator is normally used for high fluid throughput, while a horizontal separator provides a longer retention time and superior gas separating capacity. Internal design and configuration (e.g. blast chamber, baffle plate etc.) governs the individual efficiency of the equipment.

mud gas separator

Performance characteristics
The limitation to the efficiency of a mud gas separator is dedicated by:
(i) Separating Capacity – the capacity to separate gas from the liquid is determined by the internal configuration and fluid dynamic characteristics of the separator.
(ii) Venting Capacity – the capacity to vent gas through the derrick vent is subject to the backpressure of the vent line and the hydrostatic head of the liquid seal.
(iii) Liquid re-entrainment Capacity – the capacity when the liquid droplets break away from a gas/liquid interface to become suspended in the gas phase. The term re-entrainment is used in separator design because it is assumed that droplets have settled to the liquid phase and are then returned to the gas phase.

It should be noted that the capacity of the separator to separate gas from the liquid may be considerably less than the capacity to vent gas within the limit of the liquid seal.

3-Phase centrifuge produced by DC Machinery

DC Machinery is a profession manufacturer of design and produce two and three phase centrifuges. The DCLW series is a screw decanter centrifuge with a special specification. It enables three-phase separation of Oil, Water and Solid matter based on previous two-phase separation using the difference in specific gravity between solid and liquid.


Three-phase centrifuge separation by unique structure:

Separation of light and heavy liquid has been made possible by adopting the special structure of a liquid outlet dam. We also have various options available, and have good advancements for palm oil manufacturers with our high-G and anti-wear specification machines.

Working Principle:

Using two different size dams for liquid outlets, light liquid and heavy liquid separated using the centrifugal effect can be discharged separately.



1. Disposal volume is in the case of press water for fish meal, and can be altered according to the liquid disposed.
2. Motor Output can be altered according to the adopted centrifugal effect. *= On the condition of no common bed
