Tamis vibrant

This invention relates to a vibrating screen of the type comprising a base positioned in a lower part and a vibrating structure positioned in an upper part, with a plurality of elastic elements interposed between them, for connecting them and allowing the vibrating structure to elastically oscillate relative to the base. A vibrating unit is mounted on the vibrating structure to make the latter vibrate relative to the base. The upper structure comprises a plurality of sieves that are angled or parallel relative to a horizontal plane. They are positioned in such a way as to cause the outfeed of the material divided into different particle size measurement ranges.
