Abstract:
      The asymmetric rotor for the mixer was designed，and the simulation analysis and application research on the mixing processes of two asymmetric rotors and two synchronous four-wing rotors in 0°，90° and 180° phase relationships were carried.The simulation analysis showed that，when the mixing time were 5，10，15 s，the two asymmetric rotors in 90° and 180° phase relationships exhibited nearly identical dispersion effects on natural rubber （NR） particles and carbon black N330 particles.The application research showed that，when the filling coefficient of mixer was identical，the discharge temperatures corresponding to the two asymmetric rotors and the two synchronous four-wing rotors in 0°，90° and 180° phase relationships displayed negligible differences.When the filling coefficient of mixer was 0.65，the Mooney viscosity of the compound corresponding to the two asymmetric rotors in 180° phase relationship was the minimum，thet90 was shortest，the carbon black dispersion，Fmax－FL，Shore A hardness，modulus at 100 %，modulus at 300%，tensile strength and tear strength were the maximum，and the elongation at break of the compound corresponding to the two asymmetric rotors in 90° phase relationship was the maximum.
