Abstract:
1. Comminuting device for comminuting material components, comprising a housing; at least one rotor that is supported in the housing and has rotor blades or rotor teeth mounted thereon; at least one stator blade configured to be supported on the housing; and at least one screen device configured to be moved separately from an operational state of the comminuting device, downward to a maintenance state by swinging about an axle at a linked end of the screen device such that another end of the screen device that is connected to the comminuting device in the operational state is disconnected from the comminuting device in the maintenance state, wherein in the operational state, the at least one stator blade and the at least one screen device are connected to each other at the other end of the screen device that is connected to the comminuting device in the operational state and is disconnected from the comminuting device in the maintenance state; and the stator blade and the screen device are configured to be selectively moved together from the operational state to the maintenance state or relative to each other with the stator blade being connected with the housing of the comminuting device in the maintenance state.
