Shaker Screens are used in Shale Shakers as part of solid control system in drilling operations of various industries, such as oil and gas drilling, mining, coal cleaning, etc. They primarily serve the purpose of separating drilling cuttings from the drilling fluids.
A shaker screen is the key component in shale shaker equipment. They function as a sieve to block the solid drilling waste and let the precious drilling fluid to be carried to a separate channel for further treatment.
Drilling fluid is a cocktail of number of chemicals that help in the drilling process. Drilling fluid is prepared in two variations – water based and oil based, and they are very costly to obtain. They serve as lubricant agent to keep the drilling waste management equipment efficiently functioning. They keep the drilling bit cool and clean to penetrate deeper into the borehole. And because of these reasons, operators invest in technologies to lower their overall operational cost and also for the environmental purpose. Shale Shaker are one such equipment to achieve that goal.
Shaker Screens have two integral parts – a screen Panel and a screen Mesh. A screen panel will hold the mesh in place, to efficiently serve its purpose. It is much like a larger frame that holds smaller sections of the mesh with help of intersections. The frame itself comes in different material and shape. One key differentiator among them is the area of mesh between these intersection, that could be utilized for the screening. These intersections are known as “blanking”. The lower the blanking better the shaker screen’s performance.
The screen mesh could be understood as a piece of cloth woven with the wires to form fine rectangular openings. The screen mesh comes into variety in terms of its durability and conductance. Then there is a binding agent that joins the screen panel with the screen mesh.
The most modern development in shaker screen field is introduction 3D screen technology.
