A shale shaker is a screen mesh or a sieve that vibrates. The vibrating shaker screen mesh strains the slurry and liquid out of the mud. This mud is further sent to the mud tank. When the drilling equipment processes finer cuttings, they can usually be collected and recycled by a shale shaker.
The different need for a shale shaker screen is based on different mesh sizes and could be adjusted following the various API mesh number standards.
Mesh size usually is connected with the mesh number (a US measurement standard) and its relationship to the size of the openings in the screen and the size of particles that could pass through the openings. It is very easy to figure out the mesh number. All you need to do is count the number of openings in one linear inch of screen. This count is called the mesh number. A 4-mesh screen mesh means there are four small square openings across 1 inch of the screen. A 100-mesh screen means 100 openings per inch, and so on.
GN Solids Control manufactures shale shakers and screen meshes in the oil and gas industry. We provide API standards shale shaker screens for solids control shakers and mining shakers. GN shale shaker screens are compliant with API RP 13C.

How many types of shaker screens does GN have?
According to the factory stock, there are at least 3 kinds of screens: flat stainless-steel screen, wave stainless screen, and Polyurethane sieve plate. We don’t use API to describe a sieve plate. But Polyurethane sieve plates are also widely used in exploring industries.
Now, GN is able to provide replacement screens for nearly all widely known international shale shaker brands in the drilling industry.
1. GN uses robots to weld the internal steel frame to ensure consistency.
2. GN has its 3-layer design of API 60, while other suppliers in China use API 120.
3. The outer plastic material is 100% new and clean, not recycled materials.
4. The wire mesh is pre-tensioned so that the surface of the screen is stronger.
5. GN screen can be repaired with a screen rubber stopper when the damage is less than 10% of screen mesh.
All in all, GN screen meshes are well-designed and welcomed around the world. If you have a solids dewatering project and need replacement screens, don’t miss GN Solids Control!
