Three Roller Grinding Mill Operation Principles. News Introduction:Jul 17, 2017 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.Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing and compression are the primary forces used.
