ABSTRACT:
A trash shredding device (10) includes an annular drum (41) which carries vertically spaced segmented blade members (47) in tracks (48) formed therein. A paddle (44) rotates within the drum (41) with its radially outer end (46) being adjacent to the blade members (47). Trash is introduced at one axial end of the paddle (44) and is forced against the blade members (47). The trash shredded by this action is discharged from the device (10) at the other axial end of the paddle (44). The average overall sharpness of the blade members (47) is maintained by placing a new blade member (47) in the first of the tracks (48) while at the same time removing the oldest of the blade members (47) from the last of the tracks (48).
