Effect of carbon black dispersion on carbon black and ...

Usually, the three-roll mill grinds carbon black for dispersion. Commonly used dispersion media are glass beads, steel beads, and ceramic beads. The working principle of the three-roll mill grinding carbon black is to disperse and pulverize the carbon black by the shearing force and pressure against the cohesive force of the carbon black.
