ABSTRACT:
A comminuting unit of a comminuting machine for comminuting material has a plurality of knife carriers with a longitudinal axis. The knife carriers are arranged along a comminution path of the comminuting unit and have a leading longitudinal edge. The knife carriers are aligned with the longitudinal axes transversely to the comminution path and parallel to one another. The knife carriers have an axis-parallel slicing knives arranged at the leading longitudinal edge. The slicing knives have a cutting edge extending at a predetermined angle and a predetermined projecting length into the comminution path. Axial passage slots are formed between the knife carriers allowing passage of material comminuted by the slicing knives such that a rearward longitudinal edge of a preceding knife carrier and the slicing knife of the following knife carrier together define the axial passage slot in the form of a guide channel.
