Screening media of a vibrating screen for screening fractions of stone or gravel. The screening media is formed of ribs (2, 5, 10) extending from one end of the screening media to the opposite end. Pins (3, 6) projecting perpendicular from the ribs (2, 5, 10) are placed on opposite sides of the ribs (2, 5, 10). Each pin (3, 6) ends at a distance from the adjacent rib (2, 5, 10). The dimension and placement of the pins (3, 6) are such that there will be formed a continuous aperture between two adjacent ribs (2, 5, 10). Each aperture is formed of a number of rectangular screening areas (12, 13, 14) of identical size. Each screening area (12, 13, 14) is placed perpendicular to each adjacent screening area (12, 13, 14) and end areas of adjacent screening areas (12, 13, 14) coincide. |
