ROTOR

The heart and soul of the internal mixer are its rotors.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 arrangements. This ongoing commitment to research and development has resulted in the highest performance rotors available.
One of the features of the KOBELCO rotors, the Hyper-Cooling structure 3 series, suits best for the modern tire compounding and the low temperature mixing for rubber goods.

5THR

5THR Hybrid Tangential Rotor5THR Hybrid Tangential Rotor

  • High shear and reaction mixing
  • One of the best applications for Silica mixing with coupling agent
  • Kobelco Hyper-Cooling structure 3 Series
  • Providing intermeshing technology with tangential Mixers
  • Interchangeability with Kobelco 4-wing or 6-wing rotors
  • Even speed or friction ratio is possible
KIR IIKIR II

Intermeshing Rotor KIR IIIntermeshing Rotor KIR II

  • High energy input and mixing efficiency
  • Better intake than other intermeshing rotors
  • Excellent dispersion
  • Excellent for silica compounding in tire production
  • Most appropriate for rubber goods compounding
  • Kobelco Hyper-Cooling structure 3 Series
  • Even speed only
  • Request approx. 25% more drive power than 2-wing rotors
Remark : Hyper-Cooling Structure 3 Series, either 5THR or KIR-II, is not available for medium and small size mixers.
