  • Roller Mill: Components, Designs, Uses, Advantages and

    11/1/2016· Roller mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or ointments, and some solid materials. The rollers rotate at different speeds and the material is sheared as it passes through the gap.
