Fabrication of aluminum flake powder by the wet ball milling of aluminum foil scraps and the effect of related factors were studied. As foil thickness decreases from 60 to 6.5 mm, mean size of powder milled for 30 h decreases from 107 to 17 mm. It is impossible to mill the foil without oleic acid to fabricate the flake powder.
Jan 01, 1997 Wet grinding of aluminum hydroxide in a tumbling mill was conducted to investigate the effect of abrasive powder worn from the ball media on the preparation of low temperature sinterable -alumina powder. The abrasive powder worn from high purity alumina balls reduces the transformation temperature to -alumina during the calcination process.
Aluminum flake powder having high specular reflectivity is produced by wet ball milling aluminum powder in the presence of a lubricant using a volume ratio of grinding balls to powder of at least 151 and a volume ratio of grinding balls to milling liquid e.g., a light liquid hydrocarbon which preferably is substantially equal.
Within the ball mill, aluminum is shaped in to flake-like particles. The process is referred to ass wet-milling, as lubricants are added to perform as a grinding aid. The milling parameters and the lubricant are determined by the application for which the pigment is intended.
Sep 01, 2016 3.2. Methods and procedures. A stainless steel bowl was loaded with 200 g Al and 4 vol. of Al 2 O 3 powders with a ball-to-powder weight ratio of 51 meanwhile, to identify the effect of the nanoscale Al 2 O 3 reinforcements on the ball-milled composite powders, 200 g of Al without Al 2 O 3 was loaded into another stainless steel bowl. To prevent excessive cold-welding, 3 wt. of stearic ...
The process can be performed at room temperature and homogeneous nanocomposite powders can be produced. In this paper, we investigated the effect of different ball milling parameters and operating conditions milling time, ball size, processing control agent PCA and speed in mechanical alloying of aluminum powder to achieve particle size.

Nov 02, 2008 Milling aluminum without good techniques is a GREAT way to get seriously hurt and make a useless product. See, aluminum is very ductile, and when you smash two tiny bits together between anvils hard media they will squish together into a LARGER particle. I think I read the smallest youll get from ball milling Al is about 200-250 mesh.
