- Recycling Plants for Waste Wood



The ClassiSizer reduces input materials to the desired particle size in one step. The material is fed from above into the impact chamber, where it is resized with high kinetic energy by the fast rotating rotor and interaction of the particles itself. The final calibration of material is realized by screens, perforated according to the application. Further the product is collected in two discharge boxes and fed out by screws.

  • Polygonal design of the impact chamber with wear-resistant flat screens for optimal impact effect, easy exchange of individual screen segments
  • Rotor with impact elements; different adjusting angle and shape of impact elements depending on application
  • Different drive concepts (direct drive, drive via gear box), according to the application
  • Fulfilment of ATEX requirements due to different safety concepts (Q-boxes or explosion vans)
  • Stand-alone unit; on floor installation

  • Input material from small wooden particles up to offcuts
  • Feeding of inhomogeneous material mix possible
  • Variable particle size and geometry of final material due to use of screens with different mesh sizes
  • Energy-efficient size reduction due to impact technology (high kinetic energy)
  • Easy maintenance due to direct access to the impact chamber
  • Essential parts of the machine are wear protected and easy exchangeable

  • Particle board industry
  • Pellet and briquette industry
  • Biomass and renewable fuels (e.g. substrates for biogas production)
  • Dust for combustion (energy and heat generation)
  • WPC/WFC industry
  • Recycling industry (wood and non-wood)
  • Refuse-derived fuel (RDF)
