Title (EN) MATERIAL SIZING APPARATUS WITH ROD-VIBRATING DECKS
(FR) APPAREIL DE TRIAGE DE MATIERES A SURFACES VIBRANTES A TIGES
Abstract:
(EN) The present invention relates to a material separation apparatus and method. The majority of prior art devices have woven screens or straight rod screen decks that tend to clog easily. The present invention overcomes this deficiency by providing multiple screen decks, one of which has angled tines. The separating apparatus and method comprise an upper vibratory screen deck (26) and a lower vibratory screen deck (28). The upper screen deck comprises a plurality of comb-like, removable, straight elements (38), and the lower screen deck comprises transverse cross-members (56) with small diameter finger elements (58). The separating apparatus has an eccentric rotating shaft (34) secured to the upper and lower decks to impart vibratory motion thereon so that the free ends of the vibratory fingers vibrate in a generally vertical direction.
(FR) Appareil et procédé de séparation de matières. La majorité des dispositifs de l'art antérieur sont dotés de tamis tissés ou de surfaces criblantes à tiges droites tendant à se boucher facilement. L'invention résout ce problème par des surfaces criblantes mutliples dont une est pourvue de dents en angle. L'appareil et le procédé de séparation comprennent une surface criblante vibrante supérieure (26) ainsi qu'une surface criblante vibrante inférieure (28). La surface criblante inférieure comprend une pluralité d'éléments (38) en forme de peigne, amovibles, droits, et la surface criblante inférieure comprend des éléments croisés transversaux (56) pourvus de doigts de faible diamètre (58). L'appareil de séparation comporte un arbre rotatif excentrique (34) fixé aux surfaces criblantes supérieure et inférieure afin de leur conférer un mouvement vibrant de manière que les extrémités libres des doigts vibrants vibrent en sens vertical.
