KOSUN patented shale shaker is an equipment with welded structure. Vibration motor & screen plate base are installed into screen basket with special parts. Screen basket is fixed on the adjustment beam. At each of the four vertexes of the screen basket there is a vibration damping spring, which can prevent the adjoining parts and devices from being affected by the vibration. There are several screen panels on screen basket, and they are fixed and adjusted by snap-on screw bolts and hooking tensioners so that the combined effect of horizontal and vertical supporting bars may provide enough strength for screens basket. And the panels appear in an arched shape, thus making the panels more easily tensioned and more intimately connected with the frames, blessing them with longer service life as well as increasing the processing efficiency of particles.

The Economy of Linear Motion Shale Shaker
KOSUN Linear Motion Shaker is especially effective while drilling top-hole sections where heavy and high-volume solids are usually encountered. In these intervals, shakers may generate powerful G-forces and its effective vibrating motion can quickly remove the dense solids from screens and particles from wells.

The Economy of  Elliptical Motion Shale Shaker
KOSUN Balanced Elliptical Motion Shaker has a remarkable advantage in treating high viscosity drilling fluid. Under this working condition, the optimized balanced elliptical motion can effectively remove viscous solids and eliminate larger particles in drilling fluid. Meanwhile, the relatively moderate vibration strength can effectively reduce the screen consumption.

Shale shaker screen is fine mesh (single, dual or triple layered) used for filtering and separating drilling cuttings from mud (drilling fluid). It is of great importance to drilling efficiency. The shale shaker screen is a mesh screen that is created out of woven metal that goes inside the shale shaker. Whenever solids or cuttings are produced from drilling equipment, they are coated in drilling liquid. When those cuttings are shaken over shale shaker screens, the screen is able to capture all of the solid particles and allow any excess mud to drip through the screen where it can then be deposited back into the tank.

When it comes to a solid control system on any type of drilling equipment, the shale shaker is arguably the most important pieces of equipment. With drilling fluid being so important to maintaining drill performance, being able to utilize fluid efficiently is crucial. A shale shaker is what separates any drilling liquid, commonly referred to as mud, from solids, also known as cuttings. On a shale shaker, one of the most important components is the shale shaker screen. The shale shaker screen is actually what separates liquids from solids so having the correct screen can determine how effective drilling equipment operates.

There are many different types of shale shaker screens available on the market today, each with different types of weaving to create the screen and different sizes of mesh. Ultimately choosing the best screen comes down to choosing the finest mesh you possibly can that doesn’t result in drilling liquid being lost from the front of the shaker screen that match the type of shaker equipment you are using.

If you are looking for replacement shaker screens for your drilling equipment, you may consider KOSUN. All of the shale shaker screens that we offer are high quality but extremely affordable. With a wide range of mesh designs and customizable screen options available, we can provide the perfect screen for your equipment at a price you can afford. (Editor:Kosun Lily.Wang)

Separation Size and Type of KOSUN Shale Shaker

The separation size of shale shaker depends on shaker screen size. We call it API size or mesh size. The API defers from API 20 to API 325 per API RP13 standard.Through changing different API size shaker screen, the shale shaker can separate solids size min. above 40μm (at API 325 shaker screen).

If you do not need to separate so fine solids, you can choose more fine shaker screen, like 800μm.The common screen API size for shale shaker is API60, API80, API100, API140, API160. Customer can choose the suitable size per drilling mud condition.

Shale shaker is the first stage separation equipment for oilfield drilling mud cleaning system. It utilizes vibrating motor to generate vibrating strength. The vibrating strength drives the drilling mud to go through the shale shaker. When the drilling mud goes through the shaker screen, clean mud will filter into mud tank. Not allowable bigger solids will pass the screen surface and be discharged.

Types of KOSUN Shale Shaker:

Linear motion shale shaker. It is the most common shaker model for oil and gas drilling solids control system.

KOSUN Linear motion shale shaker are ideal for high-capacity processing and the compact and easy-to-service design makes them a perfect choice for fast conveyance and heavy loading in tough drilling conditions.When drilling top-hole sections or while heavy-volume solids are encountered, in these intervals, shakers are required to generate high G-forces to effectively move high-capacity drilled solids across the screens.

Balanced elliptical motion shale shaker. It is not recommended for oil and gas drilling since the flow capacity is big. If the mud flow is not equal, the motion of shaker will be changed. And performance will not be good. Mostly, professional users prefer linear motion for wide application.

KOSUN Balanced elliptical motion shale shaker are the best choice for max retention time and frequency for highly need of dryer drilled cuttings in light-loading drilling conditions.The unique balanced elliptical basket and  easy-to-service design makes them a wonderful choice for reducing solids control operation cost.When faced with gentle light-loading drilling fluids, the ES shale shakers are required to reduce G-forces and maintain longer screen residence time, this results in drier solids,better drilling fluid recovery, longer screen life andreduced operating costs.

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.

The Parts of the Shale Shaker Screen Panel

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.

Brandt Shaker Screen Replacement from Kosun

Brandt Shaker Screen

Shale shaker is a very important equipment that is used in the first stage separation of drilling liquids and the solid materials obtained from drilling oil, gas or water wells. This shale shaker consists of a shaker screen that does the separation process.

Brandt Shaker Screen comes in various types and different mesh sizes. Its two main types are the hook type and pretension type. Also the amount and the size of the solid that will get separated depends upon the size of the mesh.

Brandt Shaker Screen
Brandt Shaker Screen

Because of its importance, it is very important that the shaker screen is cleaned regularly. Cleaning it regularly will increase its efficiency and will delay the wear and tear of the mesh.
Various methods of cleaning the screen are;
1) Self Cleaning:
– This methodology involves the use of small folded or creased wires.
– These wires are arranged on a surface in such a way that small gaps are created resulting in a mesh like structure. This is usually supported using Support bars so that they are free to vibrate. These vibrations prevent the blocking or jamming of the mesh.
2) Water based cleaning:
– In this method a high pressure water pipe is used that cleans the screen by pouring water on it at a very high speed. This is a very traditional method that cleans the screen when less cleaning is required.
3) Screen cleaning machines:
– These machines are fully enclosed machines. The screen is placed inside this machine where a powerful water gun, releasing water at a very high pressure, is used that cleans the screen.
– The advantage of this machine is that it is fully automatic and no effort is needed at the workers part.
– Also this machine reduces the time required for cleaning a screen there by increasing the overall cost effectiveness.

Shale Shaker Screen Many Types | Kosun Manufacturer

Shale Shaker Screen

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.

Shaker Screen—API Standardizes Criteria for Solids Separation

Shaker Screens

Shaker Screens are the wear part of shale shaker, mainly classified into soft sieve screen, sieve plate type screen,and frame plate type screen.

The American Petroleum Institute is a trade association in the oil and natural gas industry in US. API works in collaboration with number of stake holders in the industry for the betterment of the industry.

It also conducts research and help in standardizing the industrial practices. One such guideline related to drilling industry was the standardization of criteria for solids separation. It mainly attributes to the size of shaker screens across the industry that determines the quality of fluid.

The purpose of this standardization was to simplify the screen selection process and provide the users with the screens that will make the solid separation process more efficient.
The API first came up with a Recommended Practice of drilling fluid processing system evaluation (RP 13C & E). Which was also approved by ISO 13501. This RP 13 C broadly covers the tests that describe the openings on the screen of a shale shaker screen in comparison of known standards. It should be considered that this test only describes the openings in the shaker screen but doesn’t talk about its performance.

Conformity to API standards by a manufacturer by providing the information on the labels will help the users determine their choice in best manner. A buyer will use his discretion as to which screen to use to get best conductance or increased life and so on and so forth.

Based on the standardized labeling of shale shaker  screens the buyers are likely to make a more informed decision as to what is likely to work for their needs without leaving it guess-work.
Now as it happens with any change process, not all companies might embrace the system and continue to resist, while others do label the screens with the new standards. It is the end users prerogative to ask the manufacturer to provide the test related data for the screen that they intend to purchase.

How to Install Shaker Screen for Shale Shaker?

Shaker Screen

Shale screen and Shale shaker are critical in the drilling process. Despite this, the shaker screens are delicate and prone to damage by drilling solids which occasionally break them. Having equipment that meets the industry standards and maintaining it well is inescapable.

What use is there in having a good equipment that you cannot install? Due to the crucial role they play in the solid control process, understanding how to install the shaker screen is critical.

Perhaps when you first purchased, the screen was already installed in the equipment. However, because the screen is fragile and gets damaged in the course of working, it requires occasional replacement and re-installation. The steps outlined below have been incorporated with general observances that equipment users are familiar with. They will guide you about how to install a shaker screen.
i.    As soon as it is damaged shut down the equipment, close the feeder and provide tag.
ii.    Use your hands or appropriate tools to uninstall the screen.
iii.    Clean the screens in the drilling mud using water.
iv.    Transfer drilling solids from the shale shaker by using the centrifugal sand pump and the shear pump to cut the drilling solids into smaller sizes to ease transportation.
v.    Extract the screen from the equipment.
vi.    Put the screen carefully on the table. Tighten the screen carefully using screws. For multiple-layered screens go, through the process again for each of the layers of screen.
vii.    Bolt the screen on the side with the locating bar with the cuttings outfall on the outside and plug it into the generator trailer.

Your shaker screen is now installed and you are ready to resume work. Remember that much as it is imperative for the user to know how to install the screen, choosing the screen that meets industry standards is as paramount.

Shaker Screens for Sale of Rectangular Heavy Duty (RHD)

Shaker Screens

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.

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 drilling waste management system , rectangular heavy duty shaker screens are deployed for use.

shaker screen

The main purpose of using shale shaker equipment is to separate out the drilling fluid from drilling solids i.e. drilling 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.

Derrick Shaker Screens Replacement of Kosun Manufacturer

Derrick Shaker Screens

Derrick Shaker Screens is the key component in solids control equipment used in drilling industry. Drilling operations use a borehole technology to penetrate deep beneath the surface to reach the fossil fuel, in this pursuit the mud-loggers first need to do a sampling to ascertain the depth and quality of rock they are penetrating.

In oil field digging, let’s suppose in an off-shore site, this drilling will be done with the help of drilling rig. As the drilling bit will cut through the rock underneath ocean floor, it will need some lubricant to keep it going, a drilling fluid is used for that purpose.

A drilling fluid is a rich mixture of different chemicals, either oil based or water based, this is commonly known as “drilling mud”. This drilling mud is very expensive to create, and it doesn’t only keep the equipment lubricated but also help in keeping it cool and clean for further operations.

Derrick Shaker Screens
Derrick Shaker Screens

The drilling bit will carry with itself drilling cuttings, essentially the rock shavings, mixed with drilling mud. The mud-loggers will extract these shavings from the drilling bit for their further analysis.

As explained earlier in the article, the drilling fluid is quite expensive so it is imperative for the operators to restore the drilling fluid from the drilling waste . For this purpose various solid control equipments are used, among them a shale shaker is the foremost.

A shale shaker with the help of derrick shaker screens helps in separating the drilling cuttings from drilling fluid, and the separated drilling fluid is channeled to a separate container for further processing and treatment. The dried solid, i.e. drilling cuttings are conveyed to a separate container for further treatment and disposal.

One very important factor in the solid control system is its contribution for environmental balance. If a solid control system is not efficient enough, it is likely that the drill cuttings will still carry some amount of drilling fluid that contains chemicals which could be really harmful for the environment and cause contamination of soil or ground water. The drilling industry follows strict rules on drilling waste management  for the sake of environmental impact.

In conclusion, shale shaker’s main function is to filter the drilling waste with the help of an effective derrick shaker screens and as a result help in economy of overall drilling operations and environmental prevention.
