Electrical & electronic waste

Outstanding selectivity

In the recycling of waste from electrical and electronic equipment (e-scrap), the goal is to gain marketable secondary raw materials that are as pure as possible, while safely extracting harmful components. Again and again, our Rotorshredder (type RS) has proven to be the important centerpiece of many new recycling plants. The Rotorshredder uses intense impact and shear forces to treat almost all categories of electronic and electrical waste, from small devices to washing machines, and achieves an outstanding selective disaggregation effect.

It has the following advantages:

  • Variable and adjustable crushing effect
  • Outstanding selective disaggregation
  • Low wear-related costs
  • Continuous operation
  • No melting of plastics
  • Laying open of harmful components (e.g. batteries, capacitors)
  • High availability

Following the separation of the ferrous metal fraction, the input material is further processed in the Granulator (type NG) in order to achieve a maxium particle size of 30 mm. The resulting fraction allows for the safe separation of the non-ferrous metals from the residual fraction, in particular from plastics.

In a further treatment stage, the non-ferrous metals are shaped into balls in our rotor impact mill (type RPMV) to achieve clean separation into the different non-ferrous metals (e.g. aluminum, copper, brass).

Flexible mechanical approach

The Rotorshredder RS and RPMV Rotor Impact Mill from Germany based BHS Sonthofen achieve the main objectives of processing waste from electrical and electronic equipment (WEEE), namely the effective size reduction and gentle "disintegration" of composites in order to liberate individual components. This approach is regarded by the manufacturer as extremely flexible and cost efficient.

Mechanical Processes for Recycling Waste Electric and Electronic Equipment with the Rotorshredder and Rotor Impact Mill

In plants for the recycling of waste electric and electronic equipment (WEEE) as well as for conven-
tional mineral processing, the comminution equipment dictates whether and how the specifications for the separation and sorting of the feed material are achieved. For the comminution of WEEE, the machi-
nes must meet specific requirements in respect of size reduction, insensitivity to solid components and flexibility for adapting to different feed materials. To liberate single components, composites must be broken up, but harmful components that are contaminated with pollutants should not, however, be destroyed completely. With the Rotorshredder RS and Rotor Impact Mill RPMV presented here, BHS Sonthofen supplies two machines to achieve the main objectives of WEEE processing ­ i.e. effective size reduction and gentle desintegration of composites to liberate the individual components. The achievement of these aims in combination with an extremely flexible and at the same time costeffi-
cient operation represents a leap in technology compared to conventional systems.
