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
How to order wire screen sections:
Quantity required with all dimensions

Length of the screen (in mm or feet)
Type of crimping or weave style
On slotted screen (i.e., holes are rectangular), the direction of the slot to be specified.
Edge preparation or clamping (refer diagram B)
