Dry Granulation using a Roll Compaction Machine is the process of compacting primary particles into larger granules in order to: . lock in blend ratios to prevent segregation later in the manufacturing process. improve powder flow so that …
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. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed.
