The MR 17-40 single-shaft equipped shredder is particularly suitable to shred small wastes with high resistance. 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.
