Weave In Motion process belts from GKD – Gebr. Kufferath AG are used in a wide range of applications, from the processing of minerals and sewage sludge dewatering, to the production of nonwovens and laminates.
Four types of belt are offered in the Weave In Motion product range: plastic woven belts; metal woven belts; process belts made from a combination of metal and plastic; and process meshes for the wood-processing industry. All belts are manufactured on heavy-duty looms for metallic meshes and go through finishing processes like thermal fixing, edge welding and individual edge treatments.
Here at Achema, GKD will present the Vacubelt 2015, a new polyester monofilament mesh for vacuum belt filters. The Type 2015 has been found to be particularly effective for gypsum filtration after flue gas desulphurization. It is made purely of polyester monofilaments, unlike previous mesh products that contained additional multifilament weft wires (Type 2035) or staple fibers (Type 2025). The pure monofilament design of the Type 2015 prevents it from blocking up like multifilament mesh often does. Furthermore, its smooth surface makes it easier to clean.
The Type 2015 belt provides excellent cross-stability and filtration efficiency. Laboratory tests have shown a residual-moisture content of less than 10% and significantly faster dewatering in applications using the Type 2015. Its unique mesh construction allows for an increased number of pores per area. Even with a small mesh aperture size of only 50–60 μm, air permeability is greater than that of the Type 2025 or Type 2035. This allows faster dewatering at a constant filtration rate.
Since February 2009, the Type 2015 has been used for first time, with success at a Czech coal-fired power station. “We are convinced that the belt will successfully prove its efficiency in practice with a long service life and a consistently good filtration rate,” says Kurt Widdau, the business unit manager.
