摘要：

Mixing apparatus (100) for dosing an additive (200) into a pumpable mixture (400), in particular a hydraulically setting pumpable mixture, in particular into a liquid shotcrete composition, in which the mixing apparatus (100) it has a transport line (110) for transporting the mixture (400) through the mixing apparatus (100), and a dosing device (101) that communicates with the transport line (110) is arranged for the introduction of the additive (200) in the mixture (400), characterized in that the dosing device (101) has a device (125a, 125b) for the dispersion of the additive (200) in a support medium (300), so that the additive (200) can be introduced into the mixture (400) finely distributed distributed in the support medium (300), the device (125a, 125b) for dispersing the additive being an atomizing nozzle, in particular a spiral nozzle.
