Mesh (scale) - Wikipedia

Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material.For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
