Definition Screen Size Of Ore Copper

  • Understanding Mesh Sizes

    A powders mesh size can at times be somewhat confusing. A -6 mesh powder contains particles that pass through a 6 mesh screen. A -6 mesh powder has particles that measure less than 3360 microns. A powder that is -325 mesh has particles that measure less than 44 micron. As you can see, the larger the mesh number the smaller the particle size ...
