Waste Shredders :: Limator

concasor de impact limitator

Impact Crusher for Processing of Substrates for Biogas Plants

The Limator is a versatile modular impact crusher to break up renewable resources, waste and foods for Biogas Plants. The substrates charged are broken up by the movable crusher plates and the crusher tools, as well as the momentum of the rotating substrates. This system accomplishes gentle, yet maximum possible break-up of substrates and therefore a high gas yield. The Limator can be operated continuously or in batch processing mode.

*Throughput depends on substrate and mode of operation (continuous or batch processing)


  • Increase of gas yield by improved pulping of substrate
  • Extended range of substrates can be processed because of improved pulping
  • Lower stirring times result in lower energy consumption
  • Extensive prevention of floating layers
  • Shorter pauses and therefore shorter fermentation times
  • Increase of substrate throughput without change of plant technology
  • Stabilized processing in fermentation tank by more homogenous substrate feed
  • Fewer additives for fermentation process required
  • Reduction resp. prevention of floor residue in fermentation tank
  • Improved handling of digestate in fermentation tank and at discharge
