For example, a 36 mesh screen will have 36 openings while a 150 mesh screen will have 150 openings. Since the size of the screen (one square inch) is constant, the higher the mesh number the smaller the screen opening and the smaller the particle that will pass through. Generally, US Mesh is measured using screens down to 325 mesh (325 …
