Perforated plates are also used in the field of recycling and processing technology. They are used, among other things, in screening drum technology, sorting plants, defibering plants and washing or drying devices. In the recycling industry, the robust, individually formable and durable material has proved particularly successful. It defies mechanical wear and corrosion in a wide variety of recycling processes and materials – whether plastic, wood, paper, cardboard, leaves or glass. Sheet metal is particularly suitable for recovering the valuable material glass in the area of processing technology, for example in the form of an automated screening plant. Perforated plates and sheets can also be used for numerous functions in the loading of melting furnaces.
