ABSTRACT:
A mixing apparatus having a mixer unit (7) which includes a cup-shaped stator (24, 33) and a rotor (17) located in the mixing chamber (18). Two inputs (6, 8) and an output (13) are provided. The mixing chamber (18) is divided into a plurality of mixing regions by a separating disc (20). Inner blades (21) and outer blades (22) are provided. An edge rail (37) is positioned in the plane of the separating disk (20), between the inner (21) and outer (22) blades. The stator (24, 33) has a different configuration in the various mixing areas of the mixing chamber (18). As a result, different yield and mixing ratios can be obtained in the mixing areas of the mixing chamber (18).
