Design considerations in single and multi-layered woven wire mesh combinations in solid-liquid separation

F. Edelmeier*, F. Meyer, Haver & Boecker Wire Weaving Division, Germany

The effect of different gradient structures on the load-dependent fractional separation efficiency and its dirt hold capacity have been subject of design considerations in single and multi-layered woven wire mesh combinations in solid-liquid separation.

In cooperation with the Institute of Mechanical Process Engineering in Stuttgart (IMVT) Haver & Boecker has investigated different gradient structures of wire mesh filtration media as to their influence on the load-dependent fractional separation efficiency (FAG) as well as their dirt holding capacity. In addition, different offline measurement techniques and particle systems and their influence on the result of the FAG and the dirt hold capacity were investigated and evaluated.

Square mesh fabric with opening sizes between 38 µm to 60 µm as well as filter fabric in twilled and plain weave in the pore size range between 35 µm to 45 µm and their combinations in sintered and unsintered condition have been described.

It was confirmed that by means of a specifically selected gradient structure and layer orientation, the load-dependent fractional separation efficiency as well as the dirt holding capacity are favorably influenced. This in turn has positive effects on the service life and efficiency of multi-layered metal wire mesh combinations. Blocking tendency is significantly reduced. The throughput characteristics are optimized.
