Abstract
Joint destiné à assurer l'étanchéité d'un broyeur dont l'enveloppe cylindrique rotative est percée d'une rangée circulaire de trous d'évacuation. Ces trous débouchent entre deux brides annulaires espacées de l'enveloppe dans un logement annulaire dont les parois latérales sont partiellement en contact coulissant avec les brides rotatives et comportent des rainures circulaires qui permettent d'injecter dans l'enveloppe un gaz inerte. Application aux broyeurs de matières dangereuses.
