Abstract
A mixing device comprising cooperating rotor and stator elements wherein a stator blade is arranged at the inlet to the stator element for cooperation with an axially outer end of at least one rotor blade. In use, fibrous material which is drawn into the stator element by rotation of the rotor element is shredded by the action of the cooperating rotor and stator blades. The material is then expelled radially outwardly from the stator element and is subjected to high shearing forces, which effect further mixing and disintegration, as it passes between a radially center edge of a rotor blade and the stator elements.
