This invention relates to a shredding device having a driving unit driving a rotor including shredding tools on its periphery which for comminuting a material such as waste material and/or industrial residues, interact with a least one counter knife assembly that is arranged in a stationary fashion with respect to the machine housing during the shredding operation. The shredding device is characterized in that the counter knife assembly includes at least two counter knife bars which run approximately parallel to each other and are arranged one above the other in the rotating direction of the rotor, the counter knife bars, for the compensation of wear at the shredding tools and/or at the counter knife assembly, being arranged for an adjustment radially to the rotor axis by a mutually different degree by means of an adjustment device. A process for operating a shredding device is also described.
Shredding device, comprising a driving unit driving at least one rotor, the rotor being rotatable about a rotor axis and having a periphery and having shredding tools on the periphery for comminuting shredding material such as waste material and/or production residues, the shredding tools being arranged to interact with at least one counter knife assembly that during the shredding operation of the device is arranged in a stationary manner with respect to a machine housing of the device,
Process for operating a shredding device in which a driving unit drives a rotor provided on a periphery thereof with shredding tools for comminuting shredding material such as waste material and/or production residues, the shredding tools being arranged to interact with a counter knife assembly that is stationary with respect to a machine housing during the shredding process, characterized in that for the counter knife assembly at least two counter knife bars are provided which extend approximately parallel to each and are arranged one above the other, wherein for the compensation of wear at the shredding tools and/or the counter knife assembly the at least two counter knife bars are arranged for displacement radially to an axis of the rotor by a mutually different degree.
Process according to claim 11, characterized in that pre-shredding takes place by the interaction of the upper counter knife bar in the rotating direction of the rotor with the shredding tools acting on the shredding material and re-shredding takes place by the interaction of a lower counter knife bar in the rotating direction of the rotor with the shredding tools acting on the coarsely comminuted shredding material.
