Shale shaker screen sizes selection is based on original shaker screen size. Such as the overall dimension. Shaker screen dimension, usually means the overall size of screen panel. If the screen is framed one, dimension include length, width, height or thickness. If the screen is hook strip, dimension means the length, width, and hook height or hook size.
Besides screen overall size, there are detail size on screen panels. Such as holes shape and size. The screen cloth mesh size. Effective screen area, the non blanked area, and so on.Users should also consider the certain drilling condition or mud property. The main function or achievement we need.

Almost shaker screen demand is the replacement shaker screen for present shaker. Screens replacement should be completely interchangeable with original or existing one. If user are not sure about screen mesh size or API size selection. Please toward to mud engineer, shaker screen manufacturer. Take their suggestion as reference or guidance.
Usually, at the beginning of well drilling the screen cloth request coarse opening. Thus we’ll enjoy higher frequency. When the well drilled deeper and deeper, we request finer and finer screen. As the drilling mud property and cuttings are different.
The popular shale shaker screen sizes including 700x1050mm, 630x1250mm, 585x1165mm, 710x1250mm, and so on. Mesh sizes for oilfield solids control shaker are usually from API 40-API325.
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:
-Hopper
-Feeder
-Screen Basket
-Basket Angling Mechanism
-Vibrator
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.

Shale Shaker Screen is main spare parts for shale shaker. Shale Shaker Screens are easy to be broken during the shaker operation when drilling well.
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.
Shale Shaker Screen happens to be the most dynamic part of the shale shaker equipment, as this performs the most important part of separating the solid waste from fluid in a drilling process. At the same time it is the most vulnerable part of the equipment also because it constantly deals with solid particles and chemical rich fluid that makes it prone to wear and tear easily.
Shale shaker screen has also evolved over time in design and performance. Shale shaker is the primary part of a solid drilling waste management system . The latest development in the field is the introduction of 3D screen technology.

The basis of differentiation among various types of shake shaker screen remains to be their conductance. The manufacturers apply their innovation in shapes and designs to improve it’s performance. A few common types of shale shaker screens out there are –
Flat Screen
A flat screen type is the most common and traditional type of the shaker screens that could be mounted to most of the shale shakers. A flat shaker screen is also very cost effective. This contains the steel panels that are bound together by steel plank.
Pyramid Screen
Pyramid screens are an improvised version of flat screens. A pyramid screen effectively increases the screening area without the need of changing the structure of the shaker. With help of more screening area the fluid quantity increases and results in better
production.
Metal Framed & Composite Framed Screen
Shaker Screens are usually metal framed and that standard is widely accepted in the industry. Composite frames are an extended version of the screen frames and since the introduction of composite frames, it has become quite popular among contractors due to their light weight and durability.
Hook Strip Screen
The hook strip screen comes in variations of sizes and designs and is used for straining and sieving etc. The mesh is secured with the help of clamping rails and the tension is applied with the help of woven wire cloth referred to as a hook strip.
Shale shaker screens come in variety of sizes and shapes based upon shale shaker’s make and model. A Rectangular Heavy Duty Shaker Screen is mainly used for handling heavy solid drilling cuttings taken out during oil field drilling projects.
Shale shaker screens with high quality low price was attacted by clients around the world. Shaker screen design is unique inthis industry.
Drilling as such is widely used not only in oil and gas industry but in mining and coal cleaning industries also. Wherever the project demands handling heavy duty solid drilling waste management system , rectangular heavy duty shaker screens are deployed for use.
The main purpose of using shale shaker equipment is to separate out the drilling fluid from drilling solids i.e. drilling waste cuttings.
A Rectangular Heavy Duty Shaker screen uses two layers of finely knitted mesh material and one layer of a coarse mesh to enable the handling of the heavy duty solid waste to provide it better durability and better conductance.

There had been number of incidents where during the solid control system process, while shale shaker was deployed to separate drilling cuttings from drilling fluid, some thicker parts of solid would get stuck in the circulation and make their way through multiple layers of mesh of the shaker screen and over time burst the shaker screen’s mesh cloth. To prevent such incidents, rectangular heavy duty shaker screens came into existence.
RHD shaker screens follow proprietary multi layered technology, that enhances the overall permissibility of drilling fluid through the screen with much less resistance, which naturally enhances the performance of shale shaker equipment.
The shaker screens in RHD line are available in different variations, based on the particulate size they allow to permit through and these are standardized by the America Petroleum Institute through their labeling practice. API has labeled different shaker screens based on the holes size distribution measured with the help of light.
As the technology advances, the drilling industry is all set to go through much more modernized with start to finish automation.
