Overview

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.

2-Wing S Tangential Rotor
  • General purpose
  • Temperature sensitive mixing
  • Low energy consumption
  • Good dispersion
  • Even speed or friction ratio
 

4-Wing H Tangential Rotor
  • High output and mixing efficiency
  • High long to short wing ratio,
  • Excellent ingredient dispersion
  • Smooth material flow within chamber
  • 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
  • Excellent for silica mixes
  • Increased material movement improves homogeneity
  • Even speed or friction ratio
  • Requires approx. 25% more drive power than 2-wing rotors
 

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
 

Intermeshing Rotor
  • High output and mixing efficiency
  • Good material pull-in ability
  • Excellent ingredient dispersion
  • Excellent for silica mixes
  • Even speed only
  • Requires approx. 25% more drive power than 2-wing rotors
