Abstract
a. Epurateur ou séparateur du type centrifuge. b. Epurateur caractérisé en ce qu'il comprend des éléments définissant une chambre de séparation par centrifugation dans laquelle on fait passer, en fonctionnement, une suspension en un flux de type tourbillonnaire, cette chambre possédant une entrée et une sortie, cette entrée et cette sortie étant axialement à une certaine distance l'une de l'autre, en ce qu'il comprend également des organes produisant une réduction de la section transversale de la chambre en un emplacement intermédiaire entre les emplacements de l'entrée et de la sortie, ces organes formant une surface qui se trouve sur le trajet de la portion périphérique de la suspension. c. L'invention s'applique aux épurateurs ou séparateurs du type centrifuge, en particulier pour l'industrie du papier.
