Making Aluminum Powder - Chemistry - APC Forum

Nov 01, 2008  If you put it in the ball mill for a few days, all you're likely to get is unusable and pyrophoric aluminum. A bag full of hurt, if you will. Grinding the aluminum seems like just about the hardest and slowest way you could choose to produce it. Milling aluminum without good techniques is a GREAT way to get seriously hurt and make a useless ...

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

US4629512A - Leafing aluminum pigments of improved quality ...

Aluminum pigments are produced by wet milling in the presence of water, employing a coupling agent to allow miscibility of water in the milling slurry, in order to compensate for inefficient aeration of commercial ball mills. Hydrogen peroxide may be employed to the same purpose without a coupling agent. This process assures the production of high quality leafing aluminum pigments.

Leafing aluminum pigments of improved quality - KONDIS; TOM

Air is typically blown into open trunnions, located at each end of the ball mill on the axis of rotation, to satisfy the oxygen demand for the newly-formed aluminum surfaces and to prevent the accumulation of pyrophoric aluminum powder. This air is also the source of oxygen necessary for the production of leafing aluminum pigments.

Aluminum powder (Arno Hahma; Gerald L. Hurst; Tom Perigrin)

Milled aluminum is made by performing the same process in a ball mill. The action is less compressive. It is said that stamped aluminum is denser, and gives a different reaction than the milled. ¥ Flake aluminum can also be made by the expensive process of gluing aluminum foil to sheets of paper and hammering it flatter and flatter.
