Interseroh operates five modern scrap-shredder plants throughout Germany with various outputs to process car bodies and lightweight mixed scrap.
How a scrap-shredder works
The material to be shredded is fed into the scrap-shredder by a feed belt and/or hydraulic shovel. This material is then passed over the edge of an anvil where it is broken down into small, hand-sized pieces by rotating hammers.
The hammer mill rotates with an output of 500 to 2000 BHP depending on the location of the plant.
The scrap-shredder breaks down the material so that the optimum size and a sorted, homogeneous fraction can be produced by the downstream separation technology.
Production of shredder steel scrap
The iron shares are removed from the remaining materials directly after shredding by means of magnetic separation. The shredder steel scrap produced in this way has an iron share of approx. 95% and can be used directly in steel production thanks to its good quality.
The non-ferrous residual fraction produced by the scrap-shredder process contains not only the lightweight and heavy shredder fractions subject to mandatory waste disposal but also large shares of NF metals. In order to recover these valuable raw materials our scrap-shredder plants have further downstream processing technologies. NF metals are separated from other components (e.g. rubber, wood, plastic, etc.) here with the aid of eddy current separation, for example. These are joined by further processing technologies such as drum sieves or permanent magnet drums depending on the plant.
With the help of its powerful and ultramodern scrap-shredder plants and the downstream processing technology, INTERSEROH SE makes a further contribution to environmental protection. All plants are of course approved in accordance with the Bundesimmissionsschutz-Gesetz (German control of pollution act).
