Sieving results are expressed in terms of "mesh". A minus (-)before the number indicates material passing "through" a screen. A plus (+) before the number means "retained" on a screen. For example, "50% -200 +325" means 50% by weight of the material passes through a 200 mesh screen but are retained on a +325 mesh screen or 95%-100 means 95% by weight of the material passes through a 100 mesh sieve.
Screen analysis is of particular importance when using powdered, atomized or granular aluminum for pyrotechnic manufacture. As a general rule the following expressions classify aluminum screen analysis:
COARSE................. 4 to 30 MESH
MEDIUM................. 30 to 80 MESH
FINE................... 80 to 120 MESH
Other definitions for coarse, medium, fine and extra fine:
COARSE.................. 40 to 50 MESH
MEDIUM.................. 50 to 100 MESH
FINE.................... 100 to 200 MESH
EXTRA FINE.............. 200 MESH AND DOWN
