Zwei hinsichtlich Form und Keilwinkel verschiedene Rotormesser werden eingesetzt, um den Einfluß unterschiedlicher Schnittwinkel und Messerspalte zu zeigen. Mit Zeitdehnung.

Collective cutting of OVC into small pieces in a commercially available cutting mill. The operation of two different rotors is shown. These differ from each other in respect of their shape as well as the blades fitted. In one of them, blades with a smaller lip angle are used which enable a smaller cutting angle to be employed. Close-ups show the cutting process at the stator blades and the screening of the cut material on the screen surface.
