Selecting the right shaker screens is critical during the use of shale shaker. Firstly, be clear about what material to be screened, then choose the right mesh screen that meet the screening purpose according to the particle sizes. Screen mesh is not the number of sieve pore. The parameter describing a screen includes mesh, wire mesh diameter, mesh design, conductance, non-blanked area and etc. Generally, Mesh is a measure of the number of holes in a linear inch (such as 100 mesh) or in a linear inch in each direction (such as 100 x 60 mesh).

·Eg. 200 mesh means the material get throng a screen of 200 screen pore per square inch

·Eg. 100 mesh means the material get throng a screen of 100 screen pore per square inch

·Eg. 100 mesh means the material get throng a screen of 50 screen pore per square inch

Therefore, the bigger the mesh number, the more screen pores there will be. The material to be screened is finer. The smaller the mesh number, the less screen pores there will be. The material to be screened is more coarse.
