Product Description
Product Description
Production Name:  Heavy Duty Two Roll Mixing Mill, Rubber Mill with ABB Motor
Model: XK-560
Application: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.

STEPS IN MASTICATION AND MIXING
Mastication Operation
Set the roll nip opening to 2 mm. Adjust and maintain roll temperature at 7±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-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-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.
Addition of Fillers
Increase the nip size to 3 mm. Add fillers. If large amount of fillers is to be added, divide it into 2 or 3 equal parts and add sequentially. For large amount of filler formulation pour on processing aids/plasticisers (oils) incrementally (as are the fillers), after most of the fillers have been mixed in. After each addition of filler portion make three -cuts from each side and again cut through the rubber at one end of the roll, remove it, and place it in the nip at the other end.
Note well that antioxidants may inhibits oxidative breakdown of rubber, they should be added late during mixing of natural rubber. It is advisable to add antioxidant just before the addition of sulphur and accelerator. But with synthetic rubbers an early antioxidant addition can avoid cyclization. (Reference: Moneypenny H, Menting K, Grag F. General Compounding, Rubber Compounding Chemistry and Application 2004 (373); Ed., Brendan Rodgers.)
Addition of Curatives
Add sulfur and accelerator toward the end of the mixing process to avoid premature cross-linking reaction. Make two -cuts from each side and again cut through the rubber at one end of the roll, remove it, and place it in the nip at the other end.
Sheet Out
Sheet out the compound by pressing it with your hands against the roll and allow it to roll back into itself to become a long cylindrical roll. Set the nip size to 8 mm and maintain the roll temperature at 70±5 degrees C . Pass the rolled batch endwise through the mill nip 6 times. This is a homogenization step.
Weigh the rolled batch to measure actual batch weight and % weight loss.
% wt loss = {(theoretical batch wt - actual batch wt) /theoretical batch wt} x 100
Adjust the nip size to give a sheet with minimum thickness of 6 mm when the compound is sheeted out of the mill.
