The MR 40-120 singe-shaft equipped shredder is particularly suitable to shred high quantities of industrial wastes.
The heavy structure makes the machine suitable to realize an heavy use.
A hydraulic control unit allows driving the pusher drawer. Thus, the product to be grinded is pushed towards a tools-holder rotor causing its crushing.
Thanks to a screen it is possible to select the final dimension of the shredder material.

  • Rotor diameter: 400 mm
  • Rotor length: 1200 mm
  • Number of reversible tools: 55
  • N° of usable tools sides: 4
  • Average number of rotor revolutions per min: 85
  • Weight: 5.000 kg
  • Production: 1,8-2,5 t/h.
  • Safety devices: emergency stop, drawer reversal system
  • Manufactured according to EC standards.
