Process grinds the powder materials by impactcollision 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. for wet milling, 30-40 vol of powder with 1 wt of dispersing agent such as water, alcohol or hexane is employed.
Toxic material, a totally enclosed milling system is recom-mended. enclosed systems are available for both hammer mill and jet mill operations. a product collection bag filter and a fan system are typically part of the milling system, and the negative pressure inside the milling system prevents any material from leaking out.
