Abstract
L'invention concerne un broyeur à projection sous vide dans lequel le matériau à broyer est projete par force centrifuge sur une surface d'impact. L'arbre du rotor comporte un dispositif de support d'entraînement et de guidage constitué par au moins un palier magnétique radial actif, une butée magnétique axiale active, des detecteurs radiaux et des détecteurs axiaux reliés à un circuit de commande des paliers et butée magnétiques, un moteur électrique et un ensemble de paliers à billes montés avec jeu autour de l'arbre. L'invention s'applique en particulier aux broyeurs de ciment et de minerais.
