    On A Roll Examining The Principles Of Roller Compaction

    Dec 12, 2018 Roller compaction is a method of powder compaction of dry powders into a solid mass known as the ribbon. This process is achieved by feeding powder through a set of directly opposed, counter-rotating rollers. The process avoids the use of liquids and high temperatures. The ribbon is broken down into a specific granule size via a milling system ...
