ABSTRACT:
An exact distance between the rotating knives and the stationary die plate of a pelletizer can be set and maintained during the entire pelletizing process. The drive shaft for the cutting beams and cutting knives can be heated or cooled and is supported on the knife side in a mobile bearing. As a result of the heating/cooling of the shaft, the shaft is allowed to extend through the mobile bearing in the direction of the knife head, whereby the distance between the die plate and the cutting knives rotating above the plate can be adjusted precisely and within the My range.
