  • Mobile due to the semitrailer chassis and maintenance-friendly thanks to large side doors and central lubrication.
  • A replaceable grinding basket closes the grinding chamber at the rear; 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 into the grinding chamber.
  • Short set-up times (< 10 min.) thanks to the hydraulically foldable discharge conveyor, the standard equipment includes an overband magnet.
  • The swivelling radiator is easily accessible. For self-cleaning, the large fan is reversible. The low speed of the fan keeps the noise level down.
  • The free-swinging flail holders of the flail drum (2,5 t / 5,512 lb) 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 handling by remote control and hydraulic drive. The machine can be moved by the wheel loader grab and slip-on coupling
