Abstract

A shredding apparatus for files and similar waste material, in which the waste material passes through a first cutting mechanism (3) which is designed as a "low-speed shredder" as the coarse-grade stage and afterwards passes through a second cutting mechanism (5) as a fine-grade stage. In order to eliminate problems arising from faults, to improve the shredding capacity and to improve the shredding quality, said shredding apparatus is designed in such a way that a disaggregation tool (15) is connected between the coarse-grade stage (3) and the fine-grade stage (5) in order to break up lengths of material. <IMAGE>
