<p>The screen includes rollers (1), each having an axis (1.1) with plates (1.2) parallel to one another and perpendicular to the axis itself. Between the various rollers of an axis there is an anti-clogging element (1.3) in the shape of a cylindrical tube. The anti-clogging element is free to travel and is parallel to the axis. The diameter of the anti-clogging element in the shape of a cylindrical tube is longer than the axis and shorter than the diameter of the plates.</p> |
