Sieve Granulation Description:
Powders and granular materials are sometimes described as having a certain mesh or micron size. By itself, this type of description is somewhat ambiguous. More precise specifications will indicate that a material will pass through some specific mesh or micron screen (that is, have a maximum size; larger pieces won't fit through this mesh or micron) but will be retained by some specific tighter mesh or micron (that is, a minimum size; pieces smaller than this will have passed through the mesh or micron). This type of description establishes a range of particle sizes.
