Laboratory Dispersion Kneader

The Lab Dispersion Kneader composed of a ∞ shaped mixing chamber and a pair of counter-rotated mixing rotors with differential speed of 2 to 3. Four kinds of rotor available: Roller, Cam, Banbury, and Signa. Dispersion Kneader

Main Features of the Dispersion Kneader


  • Independent heating and cooling of three side walls of the chamber
  • Easy operation, dissemble, and cleaning
  • Testing condition close to real working environment
  • High precision, sensible for minor differences of formula composition
  • Mechanical and electrical dual overload protection
  • High performance material for anti-corrosion and wear resistance
