The MR 40-140 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.
