This class consists of two-roll or three-roll open mills. A two-roll mill consists of two counter-rotating rolls that can be adjusted to move closer to each other. The nip is the distance of closest approach between the two rolls. In this type of compounding, extensive elongation mixing occurs due to the extentional flow that takes place at ...
The two-roll mill is perhaps the simplest disperser. It consists of two heated (or cooled) cylinders (also called drums or rolls) that rotate at high speeds in opposite directions, that is, toward one another (Fig. 12.9). Dispersion occurs in the space between them, termed the nip gap, or simply gap, in a manner similar to the three roll mill ...
