Abstract: The invention relates to a mixing device (1) for intermixing powder particles and/or granular particles, or a similar free-flowing solid with at least one liquid. The mixing device comprises a feed duct (5) for a solid, an inlet (17) for the liquid, at least one mixing implement (8) that is rotatable about an axis in a mixing chamber (7), and an outlet for the mixture. The device is characterised by a delivery pump (14) which is arranged between the inlet (17) and the mixing implement (8).

Abstract: A device (1) which includes a dispersing and/or homogenizing tool (2) and a pump (7) located on the same shaft (10), wherein a pumpable material can be fed from a receptacle, especially a container (3) or a pipe, to the dispersing and/or homogenizing tool (2). This material can be mixed in the dispersing and homogenizing tool (2) with an additive, which is led through a feeding line (5) and a region (5a) arranged concentric to the supply line (4) to an opening (6) before the dispersing and homogenizing tool (2). The pump (7) arranged at a distance before the opening (6) and before the dispersing and homogenizing tool (2), and has a pumping pressure in the flow direction, which, in the region of this opening (6), is less than the suctioning pressure of the tool (2).
