In the prior art, aluminum flake has been produced by various methods. Some of these methods include rotary ball mills wherein the milling media is lifted by the rotation of the mill and permitted to drop on the metal particles, thereby providing metal flake. In this method of milling, the charge can be dry or wet.

Nano-flake microstructure of Al < 45 μm powder was obtained after ball milling at 250 rpm for 2 h with an average thickness of 1.7 μm and the mean diameter of 85 μm. The flaky shape of Al < 20 μm powder was observed after ball milling at 200 rpm for 2 h with a thickness of 800 nm and diameter of 100 μm. 3.

Aluminum pigments are produced almost exclusively using the Hall process which is a wet milling process utilizing mineral spirits. Dry milling is not done due to safety concerns. Typically, mineral spirits and a fatty acid lubricant are added to the ball mills along with the aluminum powder. The slurry concentration of aluminum is only 4%.

20,257 make aluminum powder products are offered for sale by suppliers on Alibaba.com, of which aluminum powder accounts for 1%, building coating accounts for 1%, and herbal extract accounts for 1%. A wide variety of make aluminum powder options are available to you, such as halide (except chloride), chemical auxiliary agent, and alumina.

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.

In addition, dry blended powder coatings containing uncoated aluminum flake create a number of application issues. The significantly different specific gravity of powder coatings (1.2 to 1.7) compared to aluminum flake (2.7) causes particle segregation in fluidization and transport of a dry blended powder.

Granular aluminium powders, produced in a ball mill or from a jet of molten aluminium, therefore acquire a protective coat of surface oxide and are inert. With stamped aluminium powders, however, surface oxidation is prevented by lubricants added to aid the separation of these flake-like particles.

U.S. Pat. No. 3,389,105 (Bolger) describes the production of metal flake from metal powder in a ball mil or stamping mill using a fluorocarbon resin as a grinding agent, optionally in combination with a material such as stearic acid. The milling technique may be wet or dry.

milling, that differentiates one grade from another. The oversized flakes are returned to the ball mill for further processing, while remaining aluminum flakes pass into a filter press. Excess solvent is removed in the process, resulting in a filter cake having a volatile content of approximately 20%.

Aluminum flakes with metallic shine effect were thus produced. Typical properties of the produced aluminum flakes are listed in Table 1.
