where can i buy a fine mesh screen for separating aluminium powder?
i have discovered my ball mill with its large (2cm) grinding media, cant mill 100% of my aluminium powder, however it does mill roughly 50% after 8 hours, so i want to know where i can find a super thin aluminium mesh flake separator which i can periodically sift out my powder, from the powder /flake mixture.
the powder size i am looking to sift, is sufficient for use in thermite and flash powder, essentially just standard super fine aluminium powder that stains whatever it touches silvery.
i have seen one before for sale on diversehobbies before, but now its gone, and i cant find one anywhere else. does anyone here know where i can find one online?
