By comparison, in the Fig. 1b 3roll mill process, the samples are moved from the firstsecond roll to the secondthird 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 efficiently [30,31,32,33].
