A Shale Shaker Screen is a component of a drilling rig that acts as the first point of contact or first phase by which drill cuttings come in contact while entering into the shale shaker equipment. A shale shaker is a solid separation tool that helps in the removal of the large portions of cuttings from drilling fluids. Shale shaker screens are important to the shale shaker equipment used in the mining, oil and gas and coal cleaning industries for grinding and controlling drill cuttings from mud.
Shale shakers are considered to be vital components of drilling equipment. These are not only used in the upstream sector of the oil and gas industry, but also in other industries, such as ore mining and cleaning, coal mining and cleaning, etc. A shale shaker forms the very first phase of the solids control system on a drilling rig.
A typical shale shaker tank consists of the following components:
-Basket Angling Mechanism
Shale shaker screens come with a variety of frames such as steel frames, composite frames, hook strip flat type screens, pyramid shaped screens, etc. The specification of a shale shaker screen varies as per the mesh size and the mesh size is designed as per the various API screen number specifications. For example, mesh size >7801.0 TO 925.0 microns is designed as per API 20 and mesh size > 550.0 TO 655.0 microns is designed as per API 30 and so on.
KOSUN Shale shaker screen are wear part of the shale shaker, mainly classified into soft sieve screen, sieve plate type screen,and frame plate type screen.Product characteristics are wear resistance, wearability, rating of temperature, low cost, easy disassembly, conductivity ( powder ) liquid, good trapping ( dreg ) effect, etc.
Shaker screen plays a very important role in the initial stage of the solid control system. If the shaker screen is correct, then you can be assured that the process is on the right track.
With the continuous development of innovation, the further development of technology, human found a new discovery, improved the previous existence. Likewise, the shale shaker screen has undergone modification, improvement and witnessing the new presentation. There are many types of shaker screens on the market.
This is the old Derrick shaker screen model. And pyramid shaking screen is cheaper.
This is an improved version of the flat screen. Has a higher drilling fluid handling capacity than the flat screen more effective.
-Hookstrip Soft Shaker screen
This is the early use of the vibrating screen. Has been surpassed by the newer models.
Hookstrip flat screen
The Hookstrip flat screen has a vibrating screen for easy sorting, screening and screening. It is usually used by the driller. Layer 2 to 3 layers of hooks and layered screens used in plastic enhancements enhance screen saver.
This screen is commonly used in the industry. It is made of 2 to 3 layers of stainless steel, tightly tied to the frame, to make it strong. Rubber stoppers can be used to repair gaps or breaks.
This makes the screen cost-effective.
The composite screen is an improved version of the steel frame. The vibrating screen is lighter and more durable and can withstand high temperatures.

Drilling fluids shale shaker is a kind of filterable mechanical separation equipment, compared with other mechanical solids control equipment, its unit cost is kinda of economic. And it is a highly efficient separation equipment which obtains solid removal amount. Drilling fluids shale shaker is made of screen body, machine rack and gearing. Accordingly, mechanical vibration will make solid phase which is bigger than screen hole and the adhesive attraction will screen the solid phase particles which is smaller than screen hole. But all mud can’t be processed in circulating process because of the limit of shale shaker mud permit.
Usually the material of drilling fluids shale shaker is stainless knitted. Usually this kind of screen uses mesh to express the specification. Mesh is the number of screen holes, for example, a square screen that has 12 holes is called 12-mesh screen. Screen with a special outfit screen holder will screen into flake tension type fixed on the screen frame. Screen body is fixed to the rack based on spiral spring, and rubber articles’ bumper adopts the bottom-fixed type.
Oil Rig Shaker Screen Frame-Much like a canvas for painting a screen has to be supported on a frame in order to do its job, this frame differs between manufacturers in both material and shape. Screen frames can be made from materials, such as, square steel tubing, flat steel sheets, plastic type composites or they can just be supported on the ends with strips of steel ( similar idea to a scroll ). These frames consist of a rectangular shaped outer perimeter which is divided into small individual inner panels. These smaller panels differ in shape from manufacturer to manufacturer and have been known to come in shapes such as square, hexagonal, rectangular and even triangular.
These differing panel shapes are used in an attempt to reduce the quantity of panels on each frame but still provide maximum rigidity and support for the mesh attached to them. The purpose of reducing these panels is to maximize usable screening area as the walls of each panel get in the way of the mesh and prevent it from being used, this is known as “blanking”. The non-blanked screening area of a shaker screen is widely used as a selling point, the more screen surface you have available to work, the more efficient your shaker becomes and therefore can handle a higher quantity of fluid.
Screen Mesh-Just like thread is woven together to create cloth, metal wire can be woven to create a metal cloth. Screen Mesh has evolved over many years of competitive screen manufacturing resulting in very thin yet strong cloth designed to maximize screen life and conductance as well as to provide a consistent cut point. To increase the conductance of a mesh screen you have to minimize the amount of material in the way, this is done by either reducing the wire diameter or weaving the cloth to produce rectangular openings. Rectangular openings increase the screens conductance while minimizing the effect on its cut point where as square openings provide a more consistent cut point but offer a lower conductance.
To maximize screen life most manufacturers build their screens with multiple layers of mesh over a very sturdy backing cloth to further protect the cloth against solids loading and wear. The multiple layers of mesh act as a de-blinding mechanism pushing near sized particles, which may get stuck in the openings, out of the mesh reducing blinding issues and keeping the screen surface available for use.
Binding Agent-The binding agent is the material used to bind the mesh to the screen frame, it is designed to maximize adhesion to both materials while being able to handle high heat, strong vibration, abrasive cuttings and corrosive drilling fluids.
Plastic composite screens tend not to use adhesives but rather heat the mesh and melt it into the screen frame to form a bond.
3D Screen Technology-One of the more recent advances in oilfield screen technology has brought us the “3D screen”, this technology is an innovative method for increasing the screening area of a shale shaker without the need to build larger machines. When seen from the side, these screens look like corrugated cardboard, having a flat bottom and wavelike shapes on top. These waves are designed to increase the surface area of the screen panel by building up instead of out, thereby maximizing the surface area of the screen without the need to build larger shaker screens and in turn larger, heavier and more expensive shakers.

In the oilfield drilling industry, drilled solids within the drilling fluid must be removed in order to allow re-use of the drilling fluid. Efficient removal of these drilled solids results in considerable cost savings to energy companies through proper Oilfield Solids Control, reducing the treatment cost of drilling fluid, as well as protecting against catastrophic downhole tool damage and failures.
KOSUN Industries centrifuge is designed to remove the drilled solids from the drilling fluid, which allow for:
-Increased penetration rates
-Minimal drilled solids concentration
-Substantial cost savings through reduced drilling fluid maintenance, disposal costs and downhole tool protection.
-Separation of environmental and oilfield drilling fluids allowing for less environmental impact.
KOSUN has the experience that is required to design custom tailored strip sites for various applications.We understand that each application is unique and has different variables. By doing an engineering design we are able to identify target process rates, fluid parameters into and out of the site, surface equipment size restraints and deliver our clients with custom packages to suit their specific needs.
