Production stage of shale shaker in DC Workshop

Shale shaker is a common used product for water well drilling, HDD, Oil&gas drilling, CBM and ect. We have many types of shale shakers, such as linear motion, elliptical motion, dual motion accoridng to the movement locus.

Recent days, DC Machinery manufacturing a linear motion shale shaker for a India clients who are focus on Horizontal directional drilling. So far, we finished the shaker box production.


The model of the shale shaker is DCS630-3, which has 3 panel shaker screens whose dimension is 630x1250mm. Inlet flow is 120m3/h. The models is the hot sale unit in HDD industry.

All of DC shale shakers adopt Italy OLI brand motors which have the advantages of high strength vibration, large screening area, adjustable screen box angle, little noise and high efficiency. Heat treatment of the complete shaker deck.Surface painting with heavy anticorrosion to extend the service life of shale shaker.

Feeding pump- screw pump for decanter centrifuge in drilling mud process stage

Screw pump is an ideal pump for drilling mud feeding to decanter centrifuge without shearing or agitating the drilling mud. Compared to centrifugal pumps, screw pumps can move drilling mud axially without turbulence. They are also able to pump fluids of higher viscosity without losing flow rate. Also, changes in the pressure difference have little impact on screw pumps compared to centrifugal pumps.

screw pump

The main parts are screw shaft (rotor) and screw shaft bushing (stator). Because of the special geometry shape of the two parts, they form pressurize capacity separately. The fluids flow along with the shaft, inner flow speed is slow, capacity remains, pressure is steady, so it will not generate vortex and agitating. The shaft of the pump is made from Stainless steel, DC Screw pump is available for option with complete stainless steel body. It can drive by coupler, or adjust the speed by using variable speed motor, Triangle V-belt, gear box, etc.

DC is a professional oilfield drilling fluid screw pump supplier and manufacturer in China oil drilling mud solids control and drilling waste management industry.As the pioneer in this industry.

DC is capable of providing customers with series products ,such as oil & gas drilling fluid solids control equipment, decanter centrifuge, drilling waste management equipment and drilling security equipment.

Desander group manufactured for piling project

To retrieve the bentonite used in construction for engineering foundations (like diaphragm wall, piles, etc..) and some underground works, Desanders provide with a reliable and compact design which allow reuse bentonite mud after use and contaminated with sand and silt. The laws of each country requires a maximum percentage of sand in the sludge before starting concreting.


There are basically two types of Desanders: simple and double cyloning:

Desander of simple cycloning: land recommended for sandy or sandy little bit thin. Sludge only happen once the cyclone after passing through a phase of screening in order to remove larger material.

Desander of double cycloning: need for sand or fine sand with many. Similar to single cycloning, with the difference that the sludge pass twice through the cyclone so as to separate the finest sand and silt even.

Main Applications:

1- By fully purifying slurry, it is favorable to control slurry index, reduce drill stucking phenomena, and improve drilling quality.
2- By thoroughly separating the slag and soil, it is favorable to enhance drilling efficiency.
3- By realizing the repetition use of slurry, it can save slurry making materials and thus reduce the construction cost.
4- By adopting the technique of closecycle purification and low water content of removed slag, it is favorable to reduce environmental pollution.

DC solid control has the 60 m³/h, 240 m³/h size avaiable for your foundation bored pile bentonite recycling.

DCS630-3 shale shaker used for water well drilling

DC Machinery Manufacturing designs and manufactures portable mud management (shale shaking) machines for water well drilling companies. Shale shakers are often simply called “shakers.”

The model of DCS630-3 shale shaker is a professional unit for water well drilling whose treating capacity is about 120m3/h and with linear motion movement locus.

3 Panel Linear motion DCS630 shale shakers meet the needs of solids separation in a large number of different industries. To name a few, Drilling, (whether it be used in Oil and Gas as a primary or drying shaker, Water Well, or HDD), Dredging, Mining and Dewatering for waste disposal.

For water well drilling, the 3 phase solids control normally is enough, but for oil drilling especially the deep well drilling, after mud cleaner, the solids control system will fit with one middle speed decanter centrifuge for barite recovery and High gravity solids separation, and one high speed decanter centrifuge for fine and ultra fine solids (Low Gravity solids) separation.
