The apparatus for injecting one or more additives (4) into a flow (5) of a highly viscous liquid into which the additives are to be admixed comprises a supply member (3) for each additive. This supply member is releasably connected to a tube section (2) conducting the flow. Each of the supply members has a supply channel (30) for the additive which stands transversely to the direction of flow. The additives temporarily form separate phases which coexist with the phase of the highly viscous liquid after having been fed in. A wall section (1) which is oriented in the direction of flow and can be flowed about on both sides by the highly viscous liquid is associated in each case with at least some of the injection members. Its inner side (10), that lying nearer the center of the tube, spans a surface on which the exit opening (35) of the supply member at least approximately lies. The wall section is provided downstream from the discharge opening as a spreading means (11) for the additive supplied.

A mixing device for mixing a low-viscosity fluid into a high-viscosity fluid comprises the following parts: a main line for carrying the high-viscosity fluid and having inbuilt static mixing units of a main mixer; a branch line for a branch flow which is routed from the main line to the inlet of the main mixer, the main line and branch line of the main mixer being constructed from pipe sections with essentially parallel axes; a pump located in the branch line; a static auxiliary mixer at the end of the branch line; and a nozzle at the inlet to the auxiliary mixer for feeding in the low-viscosity fluid.

The static mixer for viscous media comprises a tube and at least one mixing element arranged in the tube. The tube defines a main flow direction of the fluid to be mixed. The mixing element is formed as a monolithic structure with bars crossing one another and the bars each have an essentially rectangular cross section with a large and a small side. Crossing points of the bars are reinforced by local thickened portions. As a result of these thickened portions a common boundary surface between the bars which lies parallel to the main flow direction is at least about twice as large as the square area formed by the small side.
