Powder metallurgy – basics applications

2016-5-4  alumina, zirconia. During rolling of vessel, the grinding media powder particles roll from some height. This process grinds the powder materials by impact/collision attrition. • Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid.
