Abstract
A closed mixing machine includes a pair of nonintermeshed rotors rotatable in chambers at a predetermined differential rotation ratio and having respective rotor tips set at a predetermined differential phase angle. The predetermined differential rotation ratio is set to be 1.0 and the predetermined differential phase angle is set to be 0 to 45 degrees so that the mixing machine performs improved macro-dispersion.
