Development histry of DC Solid control shale shaker
Shale shakers are the first line of defense for a properly designed solids control system. Shakers have been used on drilling rigs since the 1940’s and are a significant part of the drilling process.
Shale shakers work by removing solids from drilling fluid as the mud passes over the surface of a vibrating screen. The liquid portion of the mud and solids pass through the screen while larger solids fall off the back end and are thus discarded.
Drilling fluids are a key aspect of the drilling process and often lubricate & cool the drill bit and take drilled cuttings from the borehole. Shakers still remain the backbone of any solids control system. As time has progressed, so have these technologies; more advanced and efficient designs have been cultivated including screen technology.
For more than 10 years, DC Solid control has manufactured effective solids control and waste management equipment. DC’s driving principal is to provide quality, dependable equipment. DC Solid control is an original equipment manufacturer (OEM) of shaker screens focused on today’s drilling contractor needs. Cleaner mud, increased productivity and screen life are key to any drilling operation.

They visited many manufactures in China, seeing is believing, after the comparison on the factory capability and fabrication processing machine, finally, they chose DC as their supplier.
What Equipment Included in the Order
This order is mainly consisting of shale shaker, mud cleaner, decanter centrifuge and centrifugal type vacuum degasser. Following is the detailed speficaition of several equipment in the order.
1. The shale shaker DCS700-3 is customized design with simple shaker deck structure, easily operation on replacing the screen panels.
2. The mud cleaner is DCQG200X2/100X12 with large treating capacity. The cyclone mixer is made of wear- resistant special polyurethane material , which has good performance in fluid erosion resistance .
3.The decanter centrifuge DCLW355-1258-VFD is widely accepted by DC’s clients and there are many site level performances that could be clients’ reference. Equipped with VFD control panel, the centrifuge unit could used for both barite recovery and ultra solids dewatering process.
DC Solid control provides the main solids control equipment like shaker, decanter centrifuge, and degasser unit with control panel. For the pump unit and the mud agitator unit, if you have any requirements of solid control system, please contact us, there you will getting lowest line price and best quality product.
Which industry can use the Jet mud mixer
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. Jereh 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.
DCS700-3 Linear motion shale shaker use specification
DCS700-3 Shale shaker is a most salable model of all DC shale shakers, which is the linear motion movement locus and with the large treating capacity and low maintenance cost.
DC manufactures is a wide variety of shakers. Whether it is a standalone unit or combined with our packaged recycling systems, DC Manufacture’s shakers are built to be reliable and durable. Although the shakers differ in geometric configuration, such as physical size, number of decks, number of screens, etc., the basic operations and maintenance principles remains the same.
The Linear Motion Shaker is the backbone of a primary solid/liquid separation system. It is designed to remove course solids from a liquid to be recovered or recycled. This can take the form of dewatering coal tailings in a mining operation, separation of cuttings from drilling mud,and/or the cleaning of wastewater in a waste treatment facility. It accomplishes this by using Linear Motion Vibrator Motors and a tight screening surface.
Linear Motion Shale Shaker is designed for various solid conditions. With advantages of high G-force, wide screen area, cost-effective, Linear motion shale shakers is an ideal facility to separate the drilling fluid in petroleum industry. There’re 4 models of linear motion shale shaker for options; DCS630-3, DCS850-2, DCS700-3, DCS585-1.
DC Machinery manufactured 2 sets mud cleaner for a foreign client
This month, another 2 sets mud cleaner will arriving to Xin Gang Tian Tin port. The model of the mud cleaner is DCQJ200x2/100×4 and will used for oil& gas drilling.
Mud Cleaner is the second class and the third class solids control equipment which is the newest type to treat the drilling fluid. DC drilling mud cleaner are combined from Desander, Desilter and an Underflow Screen, at the same time Mud cleaner has the higher cleaning function compared with separated desander and desilter.
The first step in using a mud cleaner is to send the mud through a hydrocyclone, because it would be too thick for the cleaner to effectively work with. A hydrocyclone is a device that uses force to push purified mud through the top of the cyclone as thicker particles pass through the bottom section. Anything that goes through the bottom section then meets the mud cleaner.
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.
Small flow decanter centrifuge for waster water processing
Sludge dewatering is the separation of a liquid and solid phase whereby, generally, the least possible residual moisture is required in the solid phase and the lowest possible solid particle residues are required in the separated liquid phase.
DCLW Small flow decanter centrifuge is a professional unit for waster water processing unit. DC Machinery can supply treating capacity from 3-10m3/h samll flow decanter centrifuge.
In this case, the residual moisture in the dewatered solids determines the disposal costs and the centrate quality determines the pollution load returned back to the treatment facility. Minimizing both must be achieved at the lowest possible cost, with the lowest possible polymer and energy consumption, with low maintenance costs and with the lowest possible number of required operating staff.
In practice, the operator quickly realizes that there is no clearly defined operating point given daily and seasonal fluctuations; changes in system input or process configurations, as well as malfunctions of every sort always present new challenges that must be met.
The DCLW model decanter centrifuge is a highly engineered piece of process equipment designed to separate insoluble suspended solids from a liquid. The centrifuge can be used to produce a relatively dry cake from the separated solids and are flexible enough to cope with a wide fluctuation in the feed material and still achieve excellent clarification and dewatering performance.
