    Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was added to the rubber compound in the second stage. For the M-MLG route, the MLG was added directly at this stage of compounding. Finally ...

    27/04/2015  One school of thought advocate an open two-roll mill for second-stage mixing because the dispersion of the batch and the mastication is higher (than an internal mixer). Open mills, though slower, are safe for short scorch compounds. A traditional mixing line comprises of an internal mixer above a dump mill then one (or two) mill before the batch off cooling line.

    Mixing mills (also rolling mills) are used for the manufacture of rubber compounds. A rubber base material is mixed with several additives, such as fillers, softeners, processing aids and colourants here. The two rolls of the rolling mill rotate in the opposite direction. For the purpose of mixing, one roll runs faster than the other one (friction). Therefore, shearing forces act on the rubber ...
