<p>The invention is a new screen with rollers (1) for sorting solid waste, each roller comprising an axis (1.1) with plates (1.2) parallel to one another and perpendicular to the axis itself, wherein between the rollers of the same axis there is an anti-clogging element (1.3) in the shape of a cylindrical tube, free to travel and substantially parallel to the axis, and wherein the diameter of said anti-clogging element in the shape of a cylindrical tube is longer than the axis and shorter than the diameter of the plates. The edge of said parallel plates (1.2) is provided with a strip (1.21) perpendicular to the plate itself, or a with an inclined double strip, so that the plate has arrow-shaped or T-shaped section along its entire perimeter. The plates may have polygonal, circular or elliptic section. <IMAGE></p> |
