CA 2743939

A gyratory crusher has a crushing head (22) on which a first crushing shell (30) is mounted, a frame on which a second crushing shell is mounted, and a driving device, which is arranged by means of a rotating eccentric to cause the crushing head (22) to execute a gyratory movement for crushing of material. The crushing head (22) is connected to the frame by way of a rotation-restricting arrangement (40), which comprises a beater (44) in a tank (42). Spinning of the crushing head (22) is restricted by the beater (44) being braked, during operation of the crusher, by a liquid contained in the tank (42).

L'invention concerne un broyeur giratoire présentant une tête de broyage (22) sur laquelle est montée une première coque de broyage (30), un cadre sur lequel est montée une seconde coque de broyage, et un dispositif d'entraînement, agencé de manière à amener la tête de broyage (22) à effectuer un mouvement giratoire afin de broyer un matériau, au moyen d'un excentrique rotatif. La tête de broyage (22) est reliée au cadre au moyen d'un agencement limitant la rotation (40), comprenant un batteur (44) dans un réservoir (42). La rotation de la tête de broyage (22) est limitée par le batteur (44) qui est freiné, pendant le fonctionnement du broyeur, par un liquide contenu dans le réservoir (42).
