Woven wire mesh dimensions

The key dimensions of wire mesh are illustrated in Figure 2.8, for plain weave and square mesh (the usual form for plain woven wire meshes). Aperture width, w, is the distance across the aperture, between the bounding wires, measured in the projected plane at the mid positions. The wire diameter, d, is the diameter of the wire forming the mesh. The pitch, p, is the distance between the middle points of two adjacent wires and therefore is the sum of the aperture width and the wire diameter ... 

SCREEN ANALYSIS STANDARD SCREEN SERIES. Standard screens are used to measure the size (and size distribution) of particles in the size range between about 3 and 0.0015 in. (76 ram and 38 pm). Testing sieves are made of woven wire screens, the mesh and dimensions of which are carefully standardized. The openings are square. Each screen is identified in meshes per inch. The actual openings are smaller than those corresponding to the mesh numbers, however, because of the thickness of the wires. The characteristics of one common series, the Tyler standard...
