Abstract

Tambour rotatif et système de convoyeur vibrant comprenant un tambour rotatif mono-paroi (1) positionné au-dessus d'un ensemble de convoyeur vibrant (7). Le tambour rotatif peut être segmenté, chaque segment (2, 25, 26, 27) étant doté de brides d'extrémité (14, 15) qui sont connectées à un segment adjacent par des boulons (11). Un segment ou des multiples segments du tambour rotatif présentent des perforations couvertes par un capot anti-poussière (20) qui permettent au sable et aux produits de tomber du tambour à travers une structure en entonnoir (5, 19, 20) sur l'ensemble de convoyeur. L'ensemble de convoyeur vibrant comprend des convoyeurs supérieur et inférieur (28, 29), où le convoyeur supérieur collecte les produits qui tombent du tambour et fait passer le sable au convoyeur inférieur. Les produits peuvent être redirigés vers l'entrée du tambour pour être réutilisés.
