Woven wire mesh

Conveyors may be of parallel-chain, mat, slat, woven wire-mesh belt, or cast-alloy type. Automatic tensioning devices are used to maintain belt tension during heating and cooung. The product may rest directly on the conveyor or on special supports built into it. RoUer-conveyors are used for large pieces. Flame curtains are provided for sealing the ends and for protection of special treating atmospheres. 

The woven wire mesh type are formed to control the open space between the wires, thereby limiting the maximum size particle that can pass through. The cartridge is installed in cases or small vessels to facilitate quick replacement, or they can be arranged for backwash by use of proper piping connections. The wire wound units have consistent spaces for uniform particle size filtering.

The pressure drops for these units are typically low, ranging from 0.2 to 10-15 psi. The woven wire mesh runs even lower in pressure drops for the same or larger flow rates. Consult the manufacturers for specific application data.

Ferrous reinforcing (rebar rods and woven wire meshes). 

The use of metal reinforcement embedded in the slab increases its strength. Woven wire mesh is the most common material for residential applications. For slabs on grade the Council of American Building Officials,32 One and Two Family Dwelling Code recommends 6x6 in.-W2.9 x W2.9 woven wire mesh. To help control cracking, it has been suggested that this is appropriate for a basement slab as well. 

Purpose of the screens is primarily twofold (1) to change the melt s spiraling motion, caused by the screw rotation and (2) to filter contaminants out of the melt. Most plastics contain contaminants and these particles can be conveniently removed by means of a screen placed after the extruder barrel and before the melt flow reaches the extrusion die. The simplest means for filtering plastic melts are woven wire mesh disks of about the same diameter as that of the extruder barrels. Several...

According to the authors in the Encyclopedia of Chemical Technology, "The Scheibel column (A) was developed in 1948. Alternate compartments are agitated with impellers, whereas the others are packed with an open woven wire mesh. Columns up to 2.6 m in diameter are in service. 

It is often found that the sintered metal and porous ceramic supports that have been used for many academic membrane studies are very expensive, sometimes even exceeding the cost of the palladium alloy membrane by several fold. This situation cannot be accepted for commercial membrane modules, especially when a large membrane area of up to several hundred to several thousand square meters is required. Some of the least expensive membrane supports include tension springs for tubular membranes and woven wire mesh for planar membranes, but even these supports can be costly, and further development of exceptionally low cost membrane supports is needed. 

As stated above, a typical medium for the fittration of coarse materials is a woven wire mesh which will retain certain particulates on the sui ce of the screei. As the tize of the particulates decreases, other screens are required, e.g. wovai cloths, membranes, etc. these are constructed with smaller and smaller rpenings or pores. Flow fhrou such a system is shown in Figure 1.3. Where the particulates are extremely miall and in low concmtration, deposition may occur hr the dqifhs of the medium, such as in water clarification by sand...

To increase the efficiency for the electrochemical treatment of effluents rotating three-dimensional electrodes were also tested. Thus, a rotating packed bed electrode [44] and a vertically moving particle bed electrode were proposed [45, 46]. Plater barrels were also adapted for the removal of metals [47,48]. Likewise, rotating cylinder electrodes made of reticulated vitreous carbon [49], expanded metal sheets [50], woven wire meshes [51] and wedge wire screens [52] were also examined.

The current cell employs vertical DSA coated titanium anodes, vertical cathodes of woven wire mesh bolted to a perforated steel backplate, and a vacuum-deposited modified asbestos diaphragm. A single bipolar element may have 100 m of both anode and cathode active area. The anode of one element is connected to the cathode of the next by copper spring clips. This connection is immersed in the cell liquor during operation. Figures 33 B and 34 show these internal cell parts.
