Abstract (en)
[origin: CA2848911A1] The invention relates to a device for comminuting feedstock with a rotor (14) which is disposed within a housing (7), rotates about an axis of rotation (13), and is equipped over its circumference with comminuting tools (19). A ring disc (21) is attached to the front sides of the rotor (14) in each case concentrically to the axis of rotation (13). The removal of the sufficiently comminuted material occurs via a screen deck (23) extending over part of the rotor circumference. The invention provides that on the axial front sides of the screen deck (23) an arcuate sealing element (31) following the outer circumference of the ring disc (21) is disposed in each case, said element which to form a sealing gap in the plane of the ring disc (21) lies radially opposite to said disc. The sealing effect of the sealing gap between the screen deck (23) and rotor (14) uniformly over the entire length is successfully achieved in this way. It is possible further to be able to adapt the geometry of the sealing gap to the type of feedstock and its processing.
