Abbreviations and definitions for vibrating screen:
W : Aperture width distance between two adjacent wharf or weft wires.
D : Wire diameter / diameter of the wire in the wire screen.
P : Pitch
Distance between the middle points of the adjacent wires. Nominally the sum of the aperture width w and the wire diameter d (p = w + d).
K : Warp All wires running lengthwise in the screen as manufactured.
S : Weft All wires running crosswise in the screen as manufactured.
AO : Open screening area percentage of the surface of all the aperture in the total screening surface. Ratio of the square of the nominal aperture width w and the square of the nominal pitch p = (w + d), rounded to a full percentage value: Ao = 100 * (w : p)2
