Shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling.

They are considered to be the first phase of a solids control system on a drilling rig, they are used to remove large solids also called cuttings from the drilling fluid, more commonly called “Mud” due to its similar appearance.

Drilling fluids are integral to the drilling process and, among other functions, serve to lubricate and cool the drill bit as well as convey the drilled cuttings away from the bore hole. These fluids are a mixture of various chemicals in a water or oil based solution and can be very expensive to make.

For both environmental reasons and to reduce the cost of drilling operations, drilling fluid losses are minimized by stripping them away from the drilled cuttings before the cuttings are disposed of.

This is done using a multitude of specialized machines and tanks.

Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it.

DCS700-3G shale shakers are the linear motion type of shale shakers, which is mainly used in oil and gas drilling field. Today, DC Solid control shipped 12 sets DCS700-3G shale shakers to Malaysia drilling company.

The drilling mud shale shaker is the first phase solids removal equipment used in the drilling mud circulation system. The KAZS Series shale shaker are dual-motor, high frequency, linear-motion vibrating screen machines designed for fine particle separation in the oil and gas drilling mud circulation and waste slurry separation industry. It may differ in the number of screen panels and sizes according the drilling site requirement.

The DCS700-3 shale shakers have 2 long vibration motor from OLY. Treating capacity is 110m3/h, 3 pannels hookstrip shaker screens whose dimension is 700x1050mm(40- 120mesh). Dimension is 2700×1620×1500mm, weight is 1580Kg.

Besides DCS700-3 shale shakers, DC Solid contol also can design manfufacturer all models of shale shakers, such as DCS630-3. DCS850-2, DCS585-4, DCS830-3 or manufacture it according to users’ request. Hope can get your inquires of shale shakers.

 

The first line of defense for a properly designed solids control system has been and will continue to be, the shale shaker. Without proper screening of the drilling fluid during this initial removal step, reduced efficiency and effectiveness of all downstream solids control equipment in the system is assured. The downstream hydrocyclones will simply be overloaded beyond their designed capacity.

Because of their greater efficiency & complexity the use of finer mesh screens is essential. This requires more attention than the standard scalping shale shaker screen.Besides periodic lubrication, fine screen use requires the following care:
1.Wash down screens with power washer regularly
2.Check screens for tear or rips
3.Make sure screens are properly mounted
4.Make sure shaker is at proper angle
5.Check wiring or a regular basis high speed shakers tend to wear through wiring insulation

In addition, frequent checks must be made for plugging or blinding screens. The shale shaker angle can be increased or decreased to help eliminate this problem. For blinding screens a more coarse or finer screen may be installed to help solve the problem.

Remember your shale shaker is your first line of defense in your solids control system, Choose a shale shaker that is correct for your application and have rig personnel learn to use it correctly.
