Abstract:
1. Blade mill for grinding plastic material with a rotor roller which is driven in rotation inside a grinding chamber and has a plurality of radially outwards-pointing cutter blades distributed around its circumference and a plurality of stationary, radially inwards-pointing stator blades projecting into the grinding chamber and forming a blade gap with the cutter blades, wherein cutting spaces widening radially outwards in a crescent shape and located radially outside the turning circle of the rotating cutter blades are formed ahead of the stator blades in the direction of rotation of the rotor, characterized in that the motion path of the rotor blades is eccentric with respect to the axis defined by the screen baskets and in that the crescent-shaped cutting spaces are configured as relaxation spaces for the plastic material to be ground.
