Le bord terminal externe de chaque aube à palette est placé entre le niveau de liquide contenu dans le bol (20) et la surface périphérique interne du bol, et l'aube en spirale est mise en rotation le long des bords terminaux externes des aubes à palette. L'espace entre des aubes à palette adjacentes du côté du diamètre interne de l'aube en spirale est constitué par un passage (R) de transport de la matière en suspension. En outre, la partie proche d'un barrage (24) sur la surface périphérique interne du bol est décroissante de section, pour que son diamètre se réduise progressivement en direction de la partie frontale. En outre, une région (25) de drainage de la matière en suspension est décroissante de section, pour que son diamètre augmente progressivement en direction de la sortie de matière en suspension (26) à l'extrémité avant.
