Abstract

L'invention concerne une table de déshydratation (11) notamment pour déshydrater un mélange d'une boue et d'un matériau minéral, comprenant : une bande poreuse (18) présentant une face inférieure (20) et une face supérieure (19) sur laquelle destiné à être déposé ledit mélange (44); au moins deux rouleaux d'entraînement (22, 24), entre lesquels est tendue ladite bande poreuse (18), lesdits rouleaux d'entraînement (22, 24) entraînant en translation ladite bande poreuse (18) dans un sens d'entraînement (27); un moyen d'aspiration (26) installé en dessous de ladite bande poreuse pour aspirer, par dépression, l'eau contenue dans ledit mélange (44) à travers ladite bande poreuse (18), Selon l'invention, ladite table comprend en outre au moins un moyen de roulement subsidiaire (25) s'étendant transversalement au sens d'entraînement (27) et étant monté libre en rotation autour d'un axe (31), et en ce que ladite face inférieure (20) de ladite bande vient tangenter ledit moyen de roulement subsidiaire (25) de manière à entraîner en rotation ledit moyen de roulement subsidiaire (25) dans le sens d'entraînement (27).The invention relates to a dewatering table (11) in particular for dewatering a mixture of mud and mineral material, comprising: a porous strip (18) having a lower face (20) and an upper face (19) on which for depositing said mixture (44); at least two drive rollers (22, 24), between which is stretched said porous strip (18), said drive rollers (22, 24) driving said porous strip (18) in translation in a drive direction ( 27); a suction means (26) installed below said porous strip for sucking, by vacuum, the water contained in said mixture (44) through said porous strip (18), According to the invention, said table further comprises at least one subsidiary rolling means (25) extending transversely to the drive direction (27) and being mounted to rotate freely about an axis (31), and in that said lower face (20) of said strip comes to tangent said subsidiary rolling means (25) so as to rotate said subsidiary rolling means (25) in the drive direction (27).
