Abstract (en)

A wood chipping machine (1) is shown for disintegrating material (10), mainly biological material such as whole tees, branches and other forms of wooden material. The machine comprises a cutter disk (15) with one or more cutter knives (16) arranged with their cutting edges in a substantially radial plane of the disk. The cutter disk is arranged in a disk housing to be rotatable about its central axis and has a front side oriented towards a feed inlet (2) of the machine. Furthermore, the machine comprises a peripheral disintegration device (29,32-35,39-40) including one or more fixed parts that are stationary with respect to the disk housing, and one or more rotating parts that are arranged to rotate with the cutter disk during operation of the machine. The rotating parts and the fixed parts are arranged to interact with each other to sieve and disintegrate material passing towards the periphery of the disk housing.
