A three-roll mill is used mostly for dispersion, but does some grinding as well. It uses three rollers of different speeds and directions to cause the sheer force between them to disperse and grind particles. The three-roll mill is used to disperse material within a media, which is usually some type of semi-viscous material such as cream.
