‘High Efficiency Material Grinding Solutions for Industry & Research.

Fine metal powders are high value products that may be produced with the
Szego Mill by wet or paste grinding in a "locked cycle", with product recycled to
the mill inlet until the desired fineness is achieved. Softer metals such as
aluminum and copper may be ground. Cooling may be necessary for paste
grinding, for which the mill can be equipped with a cooling jacket.
Metal Powders
Aluminum

Aluminum must be ground wet since fine dry aluminum particulate can be
explosive. This material is ground as a paste in oil, mineral spirits or other
solvents. Applications include paint and other reflective coatings. Chopped
aluminum wire has been ground in the Szego Mill as a paste in mineral oil, with
stearic acid added to prevent agglomeration.
