摘要

A mixing device having at least one rotor supporting mixing blades that is also capable of being rotated. The device further includes an annular ring surrounding the rotor and having at least one axial opening and radial mixing openings associated with the mixing blades so as to allow the passage of the mixture therethrough. At least one particle-conveying line leads to the inside of said ring. The annular ring has a recirculation stage placed between the conveying line and the radial mixing openings and further includes at least two axially consecutive rows of radial openings.
