Electronic equipment and household appliances Electronic scrap often contains valuable raw materials such as copper, tin or silver. If these are to be recovered, harmful materials such as mercury (found in electronic components) and CFCs (which damage the ozone layer but are found in refrigerators) must be separated and removed, safely and reliably. Many other household appliances also contain raw materials which can be recycled. As in most recycling processes, shredding is the critical stage in this case too. Our patented four-shaft system allows us to offer a cost-effective, customer-specific shredding solution for each of the applications listed.
UNTHA four-shaft shredders are frequently used in refrigerator disposal plants where shredders reduce complete fridges to granules of no more than 40 mm in just a few seconds. The patented four-shaft system not only enables the physical separation of metal and foam so that the materials can be sorted at a later stage, but also ensures that the CFCs contained in the foam are extracted at the same time. The UNTHA four-shaft shredder can be relied on to shred electric cookers, washing machines, dish-washers, TV sets, computer monitors, complete computers including the casing, circuit boards and many other electrical and electronic appliances. The uniform, small granule size is particularly advantageous for the recovery of valuable precious metals in re-melting furnaces.
