The BHS rotor impact mill (type RPMV) is a high-performance, vertical-shaft crusher designed for the recycling industry. The rotor is circular with horseshoe-shaped impellers. This unique impeller rotor, combined with the anvil ring, selectively crushes composite materials. Materials that have different physical properties are separated; entangled materials are singled out. At the same time, ductile metals are pelletized and cleaned:

  • Hard and brittle materials are highly reduced in size
  • Composites are separated
  • Entangled material mixtures are singled out
  • Metals are shaped to balls and cleaned
  • Elastic materials are shredded

You can fine-tune this machine to your requirements by adjusting the rotor speed and the annular gap. Several different sizes with different capacities are available.

At our BHS technical center in Sonthofen, we can perform industrial tests on customer-specific materials using the RPMV rotor impact mill. In this way, we can find solutions to even the most challenging problems.

Impact Stresses for Selective Comminution - For processing slag, incineration ash and dross

Impact Stresses for Selective Comminution - For processing slag, incineration ash and dross

Metal-containing waste, e.g. slag, incineration ash and dross, are formed during the production of metals and are to be recycled as waste-derived materials. To obtain an optimal and marketable separated product from the processing of these material groups, the process parameters must be individually adjusted depending on the required final product, but series of tests conducted at the BHS test centre have shown that the above-mentioned wastederived materials can be processed in the same machine systems despite different their material properties.

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.
