Abstract

La présente invention concerne un appareil de criblage constitué non seulement d'un carter extérieur équipé de raccords d'admission de la matière à traiter et d'évacuation de la matière traitée, mais aussi de pièces d'extrémités, et également d'un tambour stationnaire de criblage (5) monté dans le carter (1) et dont la collerette (14) d'extrémité supérieure est boulonnée (20) sur une structure annulaire intermédiaire (16) de sorte que le carter (1) soutient le tambour via la structure annulaire intermédiaire (16). L'appareil comporte enfin un rotor à mouvement rotatif (6) monté à l'intérieur du tambour de criblage. La caractéristique de l'appareil de criblage est que les têtes de boulon (20) sont verrouillées en position de non rotation au moyens d'organes (18, 22) en appui sur un côté au moins d'une telle tête de boulon.
