In the rubber mixing process, two roll open mixing mill mainly relies on two relatively rotating rollers to produce squeezing and shearing effects on the rubber. The molecular chain is broken so that the various ingredients in the formula are blended uniformly. Finally, the purpose of rubber mixing is achieved.
The film discharged from the roller gap is wrapped on one roller due to the difference in surface speed and temperature of the two rollers, and then returns between the two rollers. In this way, it reciprocates many times to complete the rubber mixing effect.
When plasticizing, two roll open mixing mill promotes the molecular chain of rubber from long to short, and its elasticity from large to small. During mixing, the surface of each group of molecules of the rubber compound is constantly updated and mixed evenly. On the open mill with intermittent operation, the rubber compound passes through the roller pitch several times after feeding, and finally cuts the pieces.
