dry milling metallic pigments

US20110179971A1 - Platelet-shaped, copper-containing ...

In longitudinal extent, the metallic effect pigments of the invention, produced in particular by wet milling of copper or brass powder, are basically no different from commercially traded gold bronze pigments produced by dry milling of copper or brass powder. On an individual basis, the pigment sizes are dependent on the intended use.

Pigments & Powder | The Aluminum Association

Pigments are produced from aluminum powder and almost exclusively manufactured through a wet-milling process. Mineral spirits, an acid lubricant and aluminum powder are placed in a mill. When the mill is rotated, balls within the rotation chamber cascade the aluminum slurry in a manner that flattens and breaks the resultant flakes on impact.

Our Second - spmorell.com

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%. The mills are rotated at a speed that allows the balls ...
