<p>The invention relates to a blade mill for grinding plastic material comprising a rotor cylinder (17) which rotates in a grinding chamber and has several cutting blades (7) arranged around its periphery and extending radially to the exterior, as well as several fixed stator blades (9),which extend radially to the interior, project into the grinding chamber and together with the cutting blades form a cutting space. According to the invention, the blade mill is characterized in that, in the direction of rotation of the rotor cylinder (17), in front of the stator blades (9), cutting chambers (23) are formed which enlarge radially towards the exterior in a sickle shape, and which are positioned radially on the outside of the circle (29) described by the rotating cutting blades (7). In this way, the proper movement of the material to be ground is stabilized and the grinding process occurs in a relatively controlled fashion, allowing for considerable savings of driving energy.</p> |
