Shredder light fraction (SLF)

Today, processing shredder light fraction (a common example being ASR: automotive shredder residues) requires compliance with a growing number of regulations. At the same time, cost-effectiveness for operators must be ensured. Cost-effectiveness depends on several parameters:

• Price trends in the commodities market
• Costs of landfill disposal or incineration
• Quality of final products
• Costs of operating the recycling plant

The goal of our plant technology, which is based on our Rotorshredder (type RS), is to separate heavily tangled composites and recover metal components. Next, the remaining fraction can be separated into mineral and organic components.

Our rotor impact mill (type RPMV) is a proven solution for processing particles up to approx. 25 mm. It ball-shapes metal components and subsequently enables extensive separation of throughput material into metal fractions and other materials.

Sorting shredder light fraction without first exposing it to mechanical stress will not produce the desired results. Fine-grained and dusty material have a high tendency to clog in foam or adhere to plastic or metal. Sorting or screening alone is not enough to counter these adhesion forces. In addition, these impurities are often extremely problematic for a range of disposal procedures.
