摘要

The shredder (2) has a rotatably driven roller (20) provided with a peripheral-sided toothing (23), and a gap (28) provided between the roller and a guide plate (24), where breath of the gap is variable such that the guide plate is elastically fastened at a housing (1). The guide plate is supported at the housing in an area of an end against force of a compression spring (25), where the end is turned towards a crushing mill (3). A gas pressure damper is arranged between the guide plate and the housing and fastened at the guide plate in an area of an end.
