parison, in the Fig. 1b 3-roll mill process, the samples are moved from the rst–second roll to the second-third roll. Because of the opposite spin directions of each roll, shearing forces are generated in the space between the roll and the rolls. This force allows the sample to mix, milling, and dispersion eciently [30– 33].
