To understand the difference between mesh and microns we first need to explain how you determine the mesh. Everyone is familiar with the terminology 110 mesh, 60 mesh, 40 mesh, etc., but how are those numbers determined?
Mesh count is the number of openings in one inch of screen. For example, an 80-mesh screen has 80 openings; a 110-mesh screen has 110 openings and so forth. As the mesh number increases, the size of the openings decreases. There will be a point where you won’t be able to count those openings, and that’s where microns come into play. Beyond a 400-mesh screen, the opening size can only be defined in microns due to the fine weaving of the mesh.
