Fragments of a raw material often remain in shredders. To recover the valuable material without major outlay and without having to go through a labor-intensive, time-consuming process opening and cleaning the equipment, Bavarian company Erdwich Zerkleinerungssysteme GmbH has equipped its tried-and-tested M400 and M600 single-shaft shredders with a hydraulic Easy Cleaning system. The engineers from Erdwich are in Hannover to show for the first time how the machines can be opened and cleaned safely in minimal time.
M400 and M600 single-shaft shredders are used successfully in many different sectors. They don't just break up plastic and metal chips, castings, stamping parts, hospital waste and electrical scrap but also zinc slag, aluminum, steel and plastic. They can also prepare substitute fuels at cement plants for analysis in the laboratory. The shredders have now been revised once again for use in especially sensitive areas and optimized with the new Easy Cleaning hydraulic system. First and foremost, this will deliver benefits in sectors where sensitive or very costly materials are processed - for example in research, environmental and pharmaceutical laboratories.
Since there is in particular a growing focus on energy efficiency for exceptionally valuable materials such as gold and silver - which are used, for instance, to produce luxury goods - raw materials are increasingly being broken up before being melted and processed further, as this accelerates subsequent processes. "However, it may be that the material is not completely removed and residues remain in the machine," explains Jürgen Graf, Sales Director at Erdwich. "In the case of gold, silver or other scarce raw materials, losses of just a few grams can become an expensive matter. The newly developed hydraulic solution improves workflows and efficiency considerably and cuts material losses."
