Shale shaker screen mainly classified into soft sieve screen, sieve plate type screen,and frame plate type screen .
Any machinery will give its best performance if maintained properly, so a preventive measure is a prerequisite if an operator wants to ensure the long life of the machinery.
While routine services will take place as part of your preventive maintenance, there is something that operators themselves will be able to take care of and be rewarded with even better results. A simple way is to keep the machinery clean.
In solid control equipment, shaker screen performs that key job of eliminating the solids through the screen. So it is imperative that they are prone to damage if not kept properly clean and that will naturally increase the overall project cost.
Here are some ways to keep the shaker screen clean and safe:
• If the shaker has been idle for some time, it is important that the shaker screen be cleaned before the use. To clean the shaker screen , the best way is to use water gun or water hose.
• Usage of wire brush will actually damage the mesh, so stay clear of brushes in your cleaning process.
• The shaker screen constantly sieves the waste material and likely to get clogged with waste material and as a result the screen holes will be blinded and hamper the process if filtration. To clean the blinded screen holes, use the water hose from back side. You could consider removing the larger particles manually, but never with a brush or stick, as the mesh of the screen is prone to be torn in the process if you use any of these.
• Make sure that the screens are not left with the drilling waste i.e. drill cuttings and mud to be dried while in the screen. This will invariably lead to a pre-mature failure of the equipment.
• Never allow any worn out rubbers to be used in the equipment, this directly lowers the performance of the equipment and damages the shale shaker screen.
• Do not allow any other material to be placed over the shaker screens , either in function or in storage.
With these basic cleaning procedures, you could ensure a longer life for the shaker screen.
Hi-G dryer shaker is used to recover mud from cuttings to reduce the liquid / oil content in the cuttings to about 10% (w / w) and to recover part of the drilling mud to reduce drilling costs and reduce drilling waste Volume, reduce environmental pollution. Drying shaker screen for WBM and OBM.
Hi-G dryer shaker 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.
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.
Hi-G dryer shaker with the help of 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, drying shaker’s main function is to filter the drilling waste with the help of an effective shaker screen and as a result help in economy of overall drilling operations and environmental prevention.
Shale shaker is the first grade of solids control equipment in drilling purification system.
Shale shaker is mainly used in geographical engineering for mining of coal or other diesel products.
Increase shaker screening area- As per screening practices, decrease drilling mud amount in unit shaker screen is favorable to improve screening effect. When filled upto 80% to its capacity it performs as much as it could.
So make sure that the shaker screen is big enough to conduct screening drilling mud which always think 2:1 rate for the length to width of the screen is the best design. Thus improving shaker screen will facilitate better working of it.
Size of shaker screens matters too! When a bigger size shaker screen is used in shale shaker it not only increases the vibration strength and amplitude but also improves the hitting force and shearing force reacted by shale shaker screen to drilling mud and decreasing adhesive force between solid particles. Meanwhile, this measure is good at avoiding block of the screen to some extent, realizing drilling mud shearing and separation.
Basket angling mechanism-proper angling control the drilling mud flowing speed. Generally, big angle is faster than that of small angle. Although this practice is with big volume of shale shaker, it really does low efficiency. So, according to experience, it’s fine to keep cutting fluids speed <0.6m/S and 15 degrees for the screen.
Adding many layers screens to shale shaker- different particles are resent with different sizes thus to eliminate these multi-layer screen it can be used. Setting several layers of screen with bigger mesh form low to upper screens help to improve the shaking screen efficiency.
Proper cleansing and maintenance of it- If cleaned by brushes or sticks it can lead to damage of the screen. It is must to use proper cleansing solutions . Never use water with an oil or synthetic based mud. For maintenance of the shaker ensure the shaker components are in good order; rubber supports, tensioning mounts etc.
