· The distance/gap between the mill rolls (nip) can be varied, typically between 2 to 20 mm. Rolls Friction Ratio. The speeds of the two rolls are often different, the back roll rotating faster than the front. The difference in speed between the two rolls is called the friction ratio. The friction ratio allows a shearing action (friction) at the nip to disperse the ingredients and to force the compound to stay on .
