The three-roll planetary rolling mill mainly consists of three uniform distributed conical rollers, the external ring and the mandrel as shown in Fig. 1a. The axes of the rollers have a certain inclined angle and an offset angle with the rolled copper tube, which make the copper tube generate plastic deformation and move forward as the rollers rotate.

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.
