12.Regenerating rubber.The mixing is often done on a two-roll mill (open mill). A mill consists of two horizontally placed hollow metal cylinders (rolls) rotating towards each other. 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 one roll, preferably the front one. A friction ratio of 1.25:1 is common.
Mastication Operation
Set the roll nip opening to 2 mm. Adjust and maintain roll temperature at 70 ± 5 degrees C. Add rubber into the mill nip and band, as a continuous sheet, onto the front roll. Using a hand knife, make two ¾-cuts from each side and allow the rubber to move through the nip quite a few times until a smooth rolling bank is formed on the nip. Now the rubber is sufficiently masticated and thus becomes softer at a reduced viscosity.
Initial Addition of Ingredients
Set the nip opening to 2.5 mm. Add activators (and antidegradants if synthetic rubber) to the rolling bank. Make two ¾-cuts from each side. Cut through the rubber at one end of the roll, remove it, and place it in the nip at the other end, to ensure a homogeneous end-to-end blend.Salient Features
