Title: MIXING OR DISPERSING DEVICE AND MIXING OR DISPERSING ASSEMBLY
Abstract:
The mixing or dispersing device (1) and the mixing or dispersing assembly (36) equipped with such a device are proposed for optimising the processing of mixed or dispersed substances, in particular tablets and/or capsules for medicinal drugs. The mixing or dispersing device (1) comprises in the mixing chamber (3) a motor-driven rotor (4) comprising at least one cutting projection (8) that is bent upwards from the bottom (7) of the mixing chamber (3) and has at least one cutting edge (10). A flow-disturbing element (12) if further provided on the inner circumferential wall (11) of the mixing chamber that surrounds the axis of rotation (R), in such a way that is tapers from its first end (12), which faces the bottom (7), to its second end (13), opposite the first end (12). Furthermore, the deflection surface (15) for deflecting the mixed or dispersed substance and/or liquid being processed towards the rotor (4) is provided between the inner circumferential wall (11) and the bottom (7) of the mixing chamber (3). The at least one flow-disturbing element (12) is spaced apart from the bottom (7) of the mixing chamber (3), from the at least one cutting projection (8) and from the circular path (16) on which the at least one cutting projection (8) is movable about the axis of rotation (R) (cf. figure 7).
