Title (EN) WOOD PARTICLE SCREEN
(FR) TAMIS POUR COPEAUX DE BOIS
Abstract:
(EN) A wood particle screen (10) particularly useful for separating fines from wood chips in which a bed of flexible foraminous material (50) having holes therein sized to permit fines to pass therethrough is flexibly mounted for receiving a flow of wood chips and fines thereon. Beater rolls (60, 62, 64, 66, 68, 70, 72) are disposed beneath the screening bed, each including a plurality of spaced beater bars (92, 94, 96) so positioned as to contact the bottom of the screening bed as the bars rotate through the uppermost position of the rolls.
(FR) Est présenté un tamis pour des copeaux de bois (10) tout particulièrement utile pour séparer les fines des copeaux de bois, dans un lit de matériau foramineux souple (50) possédant des trous d'une taille permettant le passage des fines, le tamis étant monté de manière souple afin de recevoir un courant de copeaux de bois et de fines. Des cylindres de pile (60, 62, 64, 66, 68, 70, 72) sont placés sous le lit de tamisage, chacun comportant une pluralité de frappeurs espacés (92, 94, 96) et positionnés de manière à se trouver en contact avec le fond du lit de tamisage lorsqu'ils passent par la position la plus élevée des cylindres.
