<p>A shredding device comprises a rotor having a plurality of blades mounted radially thereto, the rotor being supported within a generally cylindrical housing centered about the axis of the rotor and spaced apart from the tips of the rotor blades, and the cylindrical casing presenting an uneven interior surface to the rotor for at least a part of its circumference extending from the region of a tangentially disposed outlet duct so that material introduced into the casing is repeatedly directed back and forth between the rotor blades and the surface before being discharged from the casing.</p> |
