When
dealing with metal powders as well as powder fineness, the purity or
cleanliness of the powder is a decisive criterion for judging powder
quality. Powders recovered from the grinding process must be of
maximum purity. To meet these criteria, Hosokawa designed equipment
offers wear and contamination free grinding with handling under
inert conditions.
Practical
examples include :-
-
Ultrafine
size reduction for materials such as metal oxides.
-
Air
classification for dedusting, fractionation and separation of
coarse materials.
-
Ultrafine
sieving.
-
Cleaning
of metallic alloys such as welding powder.
