dry ball milling process of powderThe wet milling process is a safe and efficient alternative to dry milling. Unlike dry milling wet milling does not cause dust to form so elaborate technical solutions such as dust removal systems inert gas purging and dedi ed containment are not necessary.
Powder properties of hydrogenated ball-milled graphite — …After milling for 40 h the graphite became significantly more disordered and the amount of desorbed hydrogen decreased. After milling up to 10 h the BET surface area increased while particle size decreased; however there is no apparent correlation between these parameters and the hydrogen storage properties of the hydrogenated ball-milled graphite.
