Thanks to the heavy gyrating mass, the flail drum with appr. 1200 rpm and the free-swinging flail holders with replaceable flail tips, this grinder is unrivalled. The quickly replaceable high speed shredding system is unique and the final product can be changed in less than 15 minutes.


  • Maintenance-friendly thanks to large side doors and central lubrication.
  • A replaceable grinding basket closes the grinding chamber at the rear end; the mesh size determines the material grain size.
  • The load-sensing scraper floor leads the material to be grinded to the heavy roller with oscillating bearing which forwards the material securely to the grinding chamber.
  • Short set-up times (< 10 min.) thanks to the hydraulically foldable discharge conveyor with optional magnetic pulley.
  • The heavy gyrating mass (1,3 t / 2,866 lb) ensures a profitable and efficient material treatment.
  • The free-swinging flail holders of the flail drum are provided with easily replaceable flail tips that can be adjusted to the materials to be grinded (e.g. hard metal, armoured tips).
  • Easy machine operation, remote control, the machine can be moved by the wheel loader bucket with grab and slip-on coupling or by the hydraulic drive.
