Abstract
A heavy-duty shredder, in particular for use in forestry, has a frame; a rotor, which is mounted on the frame so that it can rotate about an axis of rotation and has a drum coaxial with the axis of rotation; a plurality of annular discoidal sectors extending around the drum, integral with the drum and distributed along the axis of rotation so as to form annular cavities between the adjacent annular discoidal sectors; a plurality of first teeth integral with the drum and arranged in the annular cavities between two adjacent annular discoidal sectors; and a plurality of second teeth integral with the drum and aligned with the annular discoidal sectors.

A heavy-duty shredder for use in forestry, the shredder comprising:
- a frame;
- a connection for connecting the heavy-duty shredder to a vehicle;
- a rotor pivotably mounted on the frame about an axis of rotation and comprising:
- a drum coaxial to the axis of rotation;
- a plurality of annular discoidal sectors extending around the drum, integral with the drum and distributed along the axis of rotation so as to form annular cavities between adjacent annular discoidal sectors;
- a plurality of first teeth comprising a base attached to the drum and an insert, wherein each of the plurality of first teach has a cutting profile and is selectively mountable in a seat of the respective base and arranged in annular cavities between two adjacent discoidal annular sectors;
- and
- a plurality of second teeth comprising a base attached to the drum and an insert, wherein each of the plurality of second teeth has a cutting profile and is selectively mountable in a seat of the respective base and aligned with the discoidal annular sectors in a circumferential direction;
- wherein the first teeth are arranged along two first helical paths mirrored with respect to the drum centerline and the second teeth are arranged along two second helical paths mirrored with respect to the drum centerline and angularly offset by about 180° with respect to the first helical paths.
