The invention relates to a sifting device comprising a sieve box which is moved in oscillation by means of a drive (4), as a basic oscillation system having first horizontal, transversal carriers (1.3), and an additional oscillation system (2) which is fixed to the sieve box (1) and has second horizontal, transversal carriers (2.3) which are arranged parallel to said first transversal carriers. Said horizontal, second transversal carriers are respectively arranged between two first transversal carriers (1.3) and are connected to the same by means of extensible sieve lining strips (3). In the case of two successive transversal carriers, the transversal carrier which is located nearer to the feeding side (A) is positioned higher than the following transversal carrier which is nearer to the discharge side (B). The sifting device is provided with at least two sections, the difference in height between the centres of gravity of two successive transversal carriers (1.3, 2.3) being larger in the section on the feeding side than in the section on the discharge side.
Dispositif cribleur qui comporte une caisse de criblage (1) mise en oscillation par un entraînement (4) en tant que système oscillant de base, dotée de premiers supports transversaux horizontaux (1.3), et un système oscillant auxiliaire (2) fixé sur la caisse de criblage (1), doté de seconds supports transversaux horizontaux (2.3) placés parallèlement aux premiers supports transversaux. Lesdits seconds supports transversaux horizontaux sont chacun placés entre deux premiers supports transversaux (1.3) et sont reliés à ces derniers par des bandes (3) extensibles de toile métallique de criblage. Pour deux supports transversaux successifs, le support transversal qui est plus proche du côté alimentation (A) est situé plus haut que le support transversal suivant, qui est plus proche du côté évacuation (B). En outre, ce dispositif cribleur comporte au moins deux segments pour lesquels la différence de hauteur entre les centres de gravité de deux supports transversaux adjacents (1.3, 2.3) est plus importante dans le segment coté alimentation que dans le segment côté évacuation.
