The heart and soul of the internal mixer are its rotors.

KOBELCO is on the leading edge of innovative rotor design. Our research and development engineers continue to design, evaluate and test numerous cross-sectional profiles and wing configurations. This ongoing commitment to research and development has resulted in the highest performance rotors available.

5THR Hybrid Tangential Rotor

  • Designed for high shear and reactive mixing
  • Silica mixing with coupling agent is one of the best applications
  • Kobelco cooling system 3.0 (Super high cooling system) applied
  • 5THR provides intermeshing mixing technology with tangential mixers
  • 5THR has interchangeability with Kobelco 4-wing or 6-wing rotors
  • Even speed or friction ratio

Intermeshing Rotor

  • Designed for high shear and reactive mixing
  • Silica mixing with coupling agent is one of the best applications
  • Kobelco cooling system 3.0 (Super high cooling system) applied
  • Mixes highly filled/technical compounds
  • High fill factor
  • High output and mixing efficiency with stable quality from batch to batch
  • KIR II provides better intake and improved dispersion over other intermeshing rotors available today

4-Wing N Tangential Rotor

  • Avoids excessive temperature build up during mixing
  • Better uniformity of batch temperature
  • Exceptional for “final mixing”
  • Excellent for silica mixes
  • Rubber flow is more aggressive than other 4-wing rotors
  • Slimmer profile yields increased output / throughput
  • Reduced energy consumption
  • Even speed or friction ratio
  • Requires approx. 25% more drive power than 2-wing rotors

6-Wing VCMT Tangential Rotor

  • High output and mixing efficiency
  • Shorter mixing times
  • Varying wing tip to chamber side clearances
  • Varying wing tip widths
  • Excellent ingredient dispersion
