Abstract:
1. Mixing device ( 1 ) comprising a rotating drive shaft ( 2 ) that carries a pulverizing tool ( 6 ) that is formed as a rotor and has pulverizing edges ( 7 ) on an outside thereof in a radial direction and can be moved in a rotating manner relative to a stationary stator ( 8 ) that is carried by a shaft tube ( 3 ) and has pulverizing edges ( 9 ), the pulverizing edges ( 7 ) of the rotor ( 6 ) and the pulverizing edges ( 9 ) of the stator ( 8 ) apply a force to, process, or pulverize at least one of a medium located between the pulverizing edges or solids located in the medium when the rotor ( 6 ) rotates and feed the medium out from a region of the rotor ( 6 ), the pulverizing edges ( 9 ) of the stator ( 8 ) define grooves ( 10 ) or slots that are closed in the radial direction and are oriented in an axial direction, the rotor ( 6 ) has a pumping or feeding effect from an axial inlet region thereof in the axial direction, and, in an axial feed direction behind a mixing region formed from the rotor ( 6 ) and stator ( 8 ) there is at least one rolling bearing ( 12 ) through which the medium is feedable and behind which there is an outlet ( 13 ) for processed medium.
