STEPS IN MASTICATION AND MIXING. 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 ¾cuts from each side and allow the rubber to move through the nip quite a few times until a smooth rolling ...
