RUSSELL FINEX MESH

1. RUSSELL FINEX MESH

2. Low Cost Mesh 75micron/250mesh Standard market grade 75micron/250mesh Varied apertures – poor product cut Damaged wire due to poor wire drawing techniques and/or low quality stainless steel – Reduced mesh strength & Limited mesh tension Mesh defects – Major compromise on product quality Close up of wire after it has been drawn. Left picture shows surface defects. Right picture is as supplied by RF.

3. ISO 9044 The above standard allows up to 40 blemishes per standard roll. (36 M2) The above standard allows 6 aperture in every 100 to be between 25% and 50% different to the arithmetical aperture size. Material does not have to lie flat. Material can be supplied with a film of oil. Material and wire can show weaving/drawing marks.

4. The Russell Quality • Uniform apertures • No Defects • High Quality Drawing techniques – maximising wire strength • Maximum sieving efficiency – Mesh selection based on ‘Aperture & Wire diameter’ rather than ‘Mesh count’ • Sieving accuracy – optimum product cuts, consistently • Improved mesh life – High precision mesh manufacture • Reduction in frequency of re-meshing

5. 25.4mm Mesh Count = Aperture Size (mm) + Wire Dia (mm) Micron vs Mesh Count MESH COUNT The number of apertures which are counted in a row, one behind the other per inch 1 inch Aperture size (Micron) The distance between two adjacent warp or weft wires

6. Example 100 mesh (100 apertures/inch) Russell Can offer a variety of meshes dependant on the actual hole size or product cut the customer is looking for: • Selection Dependant on: • VDS • Sieve throughput (mesh loading) • Screen size • Product Characteristics
