Jul 05, 2020 One of the rollers is run by a motor and the others are rotated by friction as the material is drawn through the gap between the rollers. Roller mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or …
3. Four High Rolling Mills: In this type of mill, there are four parallel rolls one by another. In this operation, the rotation of the first and the fourth rolls take place in the opposite direction of the second and the third rolls. The second and third rolls are smaller to provide rigidity in necessity. So those are known as back up rolls.
