Abstract

1. Screening vane (1) for a rotor with drum-like base body of a screen, which are arranged on the base body distributed over the circumference and staggered over the length, with the radial outer contour of the screening vane (1) steadily increasing in direction of rotation as circular arc up to a maximum end height (H) over the rotor shell surface (15) and then abruptly dropping in the form of a concave circular arc (8) up to the rotor shell surface (15) or to 1/10 of the maximum end height (H), so that a front portion (7) is formed, whose circumferential extension (L 2) corresponds to 1.0 to 1, 5 times the maximum end height (H), and a rear portion (2), whose maximum initial height (h') at the rear edge (12) amounts to 0.2 times the maximum end height (H) and whose length (L 1) amounts to 3 to 8 times, preferably 3 to 7 times the maximum end height (H) and, characterized in that the tangent placed onto the outer contour of the screening vane (1) in the point of the maximum end height (H) runs normal to the radius passing through this point.
