Abstract

Pour l'inversion du sens de rotation des rotors de machines de broyage, un ensemble de moteurs d'entraînement (26, 28) est relié, par l'intermédiaire d'un mécanisme de changement de sens de rotation (70) avec l'ensemble de rotors (26, 28). La commande du mécanisme de changement de sens de rotation (70) a lieu de façon analogue à celle connue pour l'inversion du sens de rotation par le changement de l'alimentation de l'ensemble de moteurs d'entraînement, par conséquent par exemple, par la surveillance du courant d'alimentation tiré de l'ensemble de moteurs d'entraînement.
